一、前言
前面的几个章节介绍了很多理论基础,如:什么是WCF、WCF中的A、B、C。WCF的传输模式。本文从零开始和大家一起写一个小的WCF应用程序Demo。
大多框架的学习都是从增、删、改、查开始来学习的,我们学习WCF也是一样的。从简单来看(不包括安全、优化等相关问题),WCF的增删改查和WebForm相差无几。WCF只是把具体“实现”写在“Service端”,而“调用”放在了“Client端”。觉得有帮助别忘了点个赞哈,谢谢哦~
二、Demo说明
1)Demo的 “Service端”以本机IIS为宿主,“Client端”以WebForm项目为例。
2)Demo的“Service端”提取数据采用初学者比较容易接受的分层结构进行搭建,分别分为服务层、实体层、数据层。
引用关系如下图所示:
3)Demo以数据库为SqlServer,表User为例(sql语句在下载的压缩包中Init.sql),表结构如下所示:
字段名 |
列名 |
数据类型 |
约束 |
生成方式 |
用户编号 |
UserID |
int |
主键,必须输入 |
自动增+1 |
姓名 |
Name |
varchar(200) |
非必须输入 |
人工输入 |
密码 |
Password |
varchar(200) |
非必须输入 |
人工输入 |
描述 |
Discribe |
varchar(800) |
非必须输入 |
人工输入 |
提交时间 |
SubmitTime |
datetime |
非必须输入 |
人工输入 |
三、创建Service端宿主
1)创建WCF应用程序命名为:WCF.Demo.Service,如下图:
2)删除默认文件IService.cs与Service.svc。并分别创建增、删、改、查”Add.svc”、“Save.svc”、“Remove.svc”、“Get.svc,Search.svc”,分别对应4个功能的服务应用程序WCF服务应用程序,并创建数据操作层和数据实体层,如下图:
3)增加实体层和数据操作层代码,如下所示:
1 //用户实体 2 [DataContract] 3 public class User 4 { 5 [DataMember] 6 public int UserID { get; set; } 7 [DataMember] 8 public string UserName { get; set; } 9 [DataMember] 10 public string Password { get; set; } 11 [DataMember] 12 public string Discribe { get; set; } 13 [DataMember] 14 public DateTime SubmitTime { get; set; } 15 } 16 //数据操作,调用SqlHeler 17 public class User 18 { 19 private static readonly string connectionString = "server=.;database=wcfDemo;uid=sa;pwd=123456;"; 20 21 //添加 22 public static bool Add(Model.User user) 23 { 24 string sql = string.Format("INSERT INTO [dbo].[User]([UserName],[Password],[Discribe],[SubmitTime]) VALUES('{0}','{1}','{2}','{3}')", user.UserName, user.Password, user.Discribe, user.SubmitTime); 25 int result = SqlHelper.ExecuteNonQuery(connectionString, CommandType.Text, sql); 26 if (result > 0) 27 return true; 28 else 29 return false; 30 } 31 32 //修改 33 public static bool Save(Model.User user) 34 { 35 string sql = string.Format("UPDATE [dbo].[User] SET [UserName] = '{0}',[Discribe] = '{2}',[SubmitTime] = '{3}' WHERE UserID = {4}", user.UserName, user.Password, user.Discribe, user.SubmitTime, user.UserID); 36 int result = SqlHelper.ExecuteNonQuery(connectionString, CommandType.Text, sql); 37 if (result > 0) 38 return true; 39 else 40 return false; 41 } 42 43 //删除 44 public static bool Remove(int UserID) 45 { 46 string sql = string.Format("DELETE FROM [dbo].[User] WHERE UserID = {0}", UserID); 47 int result = SqlHelper.ExecuteNonQuery(connectionString, CommandType.Text, sql); 48 if (result > 0) 49 return true; 50 else 51 return false; 52 } 53 54 //获取用户 55 public static Model.User Get(int UserID) 56 { 57 Model.User user = new Model.User(); 58 string sql = string.Format("SELECT * FROM [dbo].[User] WHERE UserID = {0}", UserID); 59 DataSet ds = SqlHelper.ExecuteDataset(connectionString, CommandType.Text, sql); 60 if (ds != null && ds.Tables.Count > 0) 61 { 62 foreach (DataRow dr in ds.Tables[0].Rows) 63 { 64 user.UserID = Convert.ToInt32(dr["UserID"]); 65 user.UserName = dr["UserName"].ToString(); 66 user.Password = dr["Password"].ToString(); 67 user.Discribe = dr["Discribe"].ToString(); 68 user.SubmitTime = Convert.ToDateTime(dr["SubmitTime"]); 69 } 70 } 71 return user; 72 } 73 74 //获取用户列表 75 public static List<Model.User> GetUsers() 76 { 77 List<Model.User> Users = new List<Model.User>(); 78 string sql = string.Format("SELECT * FROM [dbo].[User]"); 79 DataSet ds = SqlHelper.ExecuteDataset(connectionString, CommandType.Text, sql); 80 if (ds != null && ds.Tables.Count > 0) 81 { 82 foreach (DataTable dt in ds.Tables) 83 { 84 foreach (DataRow dr in dt.Rows) 85 { 86 Model.User user = new Model.User(); 87 user.UserID = Convert.ToInt32(dr["UserID"]); 88 user.UserName = dr["UserName"].ToString(); 89 user.Password = dr["Password"].ToString(); 90 user.Discribe = dr["Discribe"].ToString(); 91 user.SubmitTime = Convert.ToDateTime(dr["SubmitTime"]); 92 Users.Add(user); 93 } 94 } 95 } 96 return Users; 97 } 98 }
4)修改Add接口的代码和实现,如下所示:
1 [ServiceContract] 2 public interface IAdd 3 { 4 [OperationContract] 5 bool DoWork(Model.User user); 6 } 7 8 public class Add : IAdd 9 { 10 public bool DoWork(Model.User user) 11 { 12 return DAL.User.Add(user); 13 } 14 }
5)修改Save接口的代码和实现,如下所示:
1 [ServiceContract] 2 public interface ISave 3 { 4 [OperationContract] 5 bool DoWork(Model.User user); 6 } 7 8 public class Save : ISave 9 { 10 public bool DoWork(Model.User user) 11 { 12 return DAL.User.Save(user); 13 } 14 }
6)修改Remove接口的代码和实现,如下所示:
1 [ServiceContract] 2 public interface IRemove 3 { 4 [OperationContract] 5 bool DoWork(int UserID); 6 } 7 public class Remove : IRemove 8 { 9 public bool DoWork(int UserID) 10 { 11 return DAL.User.Remove(UserID); 12 } 13 }
7)修改Search接口的代码和实现,如下所示:
1 [ServiceContract] 2 public interface ISearch 3 { 4 [OperationContract] 5 List<Model.User> DoWork(); 6 } 7 8 public class Search : ISearch 9 { 10 List<Model.User> ISearch.DoWork() 11 { 12 return DAL.User.GetUsers(); 13 } 14 }
8)修改Get接口的代码和实现,如下所示:
1 [ServiceContract] 2 public interface IGet 3 { 4 [OperationContract] 5 Model.User DoWork(int UserID); 6 } 7 8 public class Get : IGet 9 { 10 public Model.User DoWork(int UserID) 11 { 12 return DAL.User.Get(UserID); 13 } 14 }
四、部署服务端程序
1)将程序发布,并部署到IIS上,设置端口:8080,如下图所示:
2)以Add.svc服务应用程序为目标,测试部署是否成功,成功后如下图所示:
五、创建Client端Web应用程序
新建WebForm项目WCF.Demo.Client,并创建增删改查文件,Add.aspx,Save.aspx,SearchAndRemove.aspx。如下图所示:
六、使用SvcUtil.exe生成客户端代码和配置
SvcUtil.exe是一个VS命令行工具,该工具位于:C:Program FilesMicrosoft SDKsWindowsv7.0Ain 或 C:Program Files (x86)Microsoft SDKsWindowsv7.0Ain一般情况下我们将SvcUtil.exe添加到VS开发工具中方便以后的运用(也可直接使用该命令行工具)。
1)在VS中的 Tools菜单---选择External Tools,打开管理窗口如下图所示:
在Title中输入SvcUtil,Command中选择SvcUtil.exe全路径,Initial directory栏选择生成的客户端代码和配置文件所放的目录(此处为解决方案所在目录),选上Prompt for arguments,不选上Close on exit。点击OK.
2)添加完成后,在VS的工具下会出现这个菜单。如下图所示:
3)在Client端添加对服务的引用。打开SvUtil工具,在Arguments里填写服务的地址,如下图:
点击OK后出现下图,说明代码类和配置文件生成成功(在解决方案目标下),如下图所示:
此时代理类和配置文件被下载到解决方案的物理目录中,如下图所示:
七、在Client端使用代理类与配置
将代理类从服务端的物理目录拷贝出来,放到Client端,并适当的修改代码,加入自己需要的名称空间,如下图所示:
使用代码如下所示:
1 //增加 2 public partial class Add : System.Web.UI.Page 3 { 4 Service.AddClient addClient = new Service.AddClient(); 5 protected void Page_Load(object sender, EventArgs e) 6 { 7 8 } 9 10 //提交 11 protected void btnSubmit_Click(object sender, EventArgs e) 12 { 13 Model.User user = new Model.User(); 14 user.UserName = this.txtUserName.Text; 15 user.Password = this.txtPassword.Text; 16 user.Discribe = this.txtDiscribe.Text; 17 user.SubmitTime = System.DateTime.Now; 18 addClient.DoWork(user); 19 Response.Write("添加成功!"); 20 } 21 } 22 //修改 23 public partial class Save : System.Web.UI.Page 24 { 25 Service.SaveClient saveClient = new Service.SaveClient(); 26 Service.GetClient getClient = new Service.GetClient(); 27 protected void Page_Load(object sender, EventArgs e) 28 { 29 if (!Page.IsPostBack && !string.IsNullOrEmpty(Request.QueryString["UserID"])) 30 { 31 GetUser(); 32 } 33 } 34 35 protected void GetUser() 36 { 37 int UserID = Convert.ToInt32(Request.QueryString["UserID"]); 38 Model.User user = getClient.DoWork(UserID); 39 this.txtUserName.Text = user.UserName; 40 this.txtDiscribe.Text = user.Discribe; 41 } 42 43 //提交 44 protected void btnSubmit_Click(object sender, EventArgs e) 45 { 46 int UserID = Convert.ToInt32(Request.QueryString["UserID"]); 47 Model.User user = getClient.DoWork(UserID); 48 user.UserName = this.txtUserName.Text; 49 user.Discribe = this.txtDiscribe.Text; 50 saveClient.DoWork(user); 51 Response.Write("修改成功!"); 52 } 53 } 54 //列表及删除 55 public partial class SearchAndRemove : System.Web.UI.Page 56 { 57 Service.SearchClient searchClient = new Service.SearchClient(); 58 Service.RemoveClient removeClient = new Service.RemoveClient(); 59 protected void Page_Load(object sender, EventArgs e) 60 { 61 if (!Page.IsPostBack) 62 { 63 GetUsers(); 64 } 65 } 66 67 protected void GetUsers() 68 { 69 this.repUsers.DataSource = searchClient.DoWork(); 70 this.repUsers.DataBind(); 71 } 72 73 protected void lbtnRemoveCommand(object sender, CommandEventArgs e) 74 { 75 int UserID = Convert.ToInt32(e.CommandName); 76 removeClient.DoWork(UserID); 77 Response.Write("删除成功~"); 78 GetUsers(); 79 } 80 }
将生成的配置文件中的 <system.serviceModel>复制到Client的Web.config中,代码如下:
1 <system.serviceModel> 2 <bindings> 3 <basicHttpBinding> 4 <binding name="BasicHttpBinding_IAdd" closeTimeout="00:01:00" 5 openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" 6 allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" 7 maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" 8 messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" 9 useDefaultWebProxy="true"> 10 <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" 11 maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 12 <security mode="None"> 13 <transport clientCredentialType="None" proxyCredentialType="None" 14 realm="" /> 15 <message clientCredentialType="UserName" algorithmSuite="Default" /> 16 </security> 17 </binding> 18 <binding name="BasicHttpBinding_IRemove" closeTimeout="00:01:00" 19 openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" 20 allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" 21 maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" 22 messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" 23 useDefaultWebProxy="true"> 24 <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" 25 maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 26 <security mode="None"> 27 <transport clientCredentialType="None" proxyCredentialType="None" 28 realm="" /> 29 <message clientCredentialType="UserName" algorithmSuite="Default" /> 30 </security> 31 </binding> 32 <binding name="BasicHttpBinding_ISearch" closeTimeout="00:01:00" 33 openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" 34 allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" 35 maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" 36 messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" 37 useDefaultWebProxy="true"> 38 <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" 39 maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 40 <security mode="None"> 41 <transport clientCredentialType="None" proxyCredentialType="None" 42 realm="" /> 43 <message clientCredentialType="UserName" algorithmSuite="Default" /> 44 </security> 45 </binding> 46 <binding name="BasicHttpBinding_ISave" closeTimeout="00:01:00" 47 openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" 48 allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" 49 maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" 50 messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" 51 useDefaultWebProxy="true"> 52 <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" 53 maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 54 <security mode="None"> 55 <transport clientCredentialType="None" proxyCredentialType="None" 56 realm="" /> 57 <message clientCredentialType="UserName" algorithmSuite="Default" /> 58 </security> 59 </binding> 60 <binding name="BasicHttpBinding_IGet" closeTimeout="00:01:00" 61 openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" 62 allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" 63 maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" 64 messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" 65 useDefaultWebProxy="true"> 66 <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" 67 maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 68 <security mode="None"> 69 <transport clientCredentialType="None" proxyCredentialType="None" 70 realm="" /> 71 <message clientCredentialType="UserName" algorithmSuite="Default" /> 72 </security> 73 </binding> 74 </basicHttpBinding> 75 </bindings> 76 <client> 77 <endpoint address="http://localhost:8080/Add.svc" binding="basicHttpBinding" 78 bindingConfiguration="BasicHttpBinding_IAdd" contract="IAdd" 79 name="BasicHttpBinding_IAdd" /> 80 <endpoint address="http://localhost:8080/Remove.svc" binding="basicHttpBinding" 81 bindingConfiguration="BasicHttpBinding_IRemove" contract="IRemove" 82 name="BasicHttpBinding_IRemove" /> 83 <endpoint address="http://localhost:8080/Search.svc" binding="basicHttpBinding" 84 bindingConfiguration="BasicHttpBinding_ISearch" contract="ISearch" 85 name="BasicHttpBinding_ISearch" /> 86 <endpoint address="http://localhost:8080/Save.svc" binding="basicHttpBinding" 87 bindingConfiguration="BasicHttpBinding_ISave" contract="ISave" 88 name="BasicHttpBinding_ISave" /> 89 <endpoint address="http://localhost:8080/Get.svc" binding="basicHttpBinding" 90 bindingConfiguration="BasicHttpBinding_IGet" contract="IGet" 91 name="BasicHttpBinding_IGet" /> 92 </client> 93 </system.serviceModel>

将代理类从服务端的物理目录拷贝出来,放到Client端,并适当的修改代码,加入自己需要的名称空间,如下图所示:
使用代码如下所示:
1 //增加 2 public partial class Add : System.Web.UI.Page 3 { 4 Service.AddClient addClient = new Service.AddClient(); 5 protected void Page_Load(object sender, EventArgs e) 6 { 7 8 } 9 10 //提交 11 protected void btnSubmit_Click(object sender, EventArgs e) 12 { 13 Model.User user = new Model.User(); 14 user.UserName = this.txtUserName.Text; 15 user.Password = this.txtPassword.Text; 16 user.Discribe = this.txtDiscribe.Text; 17 user.SubmitTime = System.DateTime.Now; 18 addClient.DoWork(user); 19 Response.Write("添加成功!"); 20 } 21 } 22 //修改 23 public partial class Save : System.Web.UI.Page 24 { 25 Service.SaveClient saveClient = new Service.SaveClient(); 26 Service.GetClient getClient = new Service.GetClient(); 27 protected void Page_Load(object sender, EventArgs e) 28 { 29 if (!Page.IsPostBack && !string.IsNullOrEmpty(Request.QueryString["UserID"])) 30 { 31 GetUser(); 32 } 33 } 34 35 protected void GetUser() 36 { 37 int UserID = Convert.ToInt32(Request.QueryString["UserID"]); 38 Model.User user = getClient.DoWork(UserID); 39 this.txtUserName.Text = user.UserName; 40 this.txtDiscribe.Text = user.Discribe; 41 } 42 43 //提交 44 protected void btnSubmit_Click(object sender, EventArgs e) 45 { 46 int UserID = Convert.ToInt32(Request.QueryString["UserID"]); 47 Model.User user = getClient.DoWork(UserID); 48 user.UserName = this.txtUserName.Text; 49 user.Discribe = this.txtDiscribe.Text; 50 saveClient.DoWork(user); 51 Response.Write("修改成功!"); 52 } 53 } 54 //列表及删除 55 public partial class SearchAndRemove : System.Web.UI.Page 56 { 57 Service.SearchClient searchClient = new Service.SearchClient(); 58 Service.RemoveClient removeClient = new Service.RemoveClient(); 59 protected void Page_Load(object sender, EventArgs e) 60 { 61 if (!Page.IsPostBack) 62 { 63 GetUsers(); 64 } 65 } 66 67 protected void GetUsers() 68 { 69 this.repUsers.DataSource = searchClient.DoWork(); 70 this.repUsers.DataBind(); 71 } 72 73 protected void lbtnRemoveCommand(object sender, CommandEventArgs e) 74 { 75 int UserID = Convert.ToInt32(e.CommandName); 76 removeClient.DoWork(UserID); 77 Response.Write("删除成功~"); 78 GetUsers(); 79 } 80 }
将生成的配置文件中的 <system.serviceModel>复制到Client的Web.config中,代码如下:
1 <system.serviceModel> 2 <bindings> 3 <basicHttpBinding> 4 <binding name="BasicHttpBinding_IAdd" closeTimeout="00:01:00" 5 openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" 6 allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" 7 maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" 8 messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" 9 useDefaultWebProxy="true"> 10 <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" 11 maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 12 <security mode="None"> 13 <transport clientCredentialType="None" proxyCredentialType="None" 14 realm="" /> 15 <message clientCredentialType="UserName" algorithmSuite="Default" /> 16 </security> 17 </binding> 18 <binding name="BasicHttpBinding_IRemove" closeTimeout="00:01:00" 19 openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" 20 allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" 21 maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" 22 messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" 23 useDefaultWebProxy="true"> 24 <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" 25 maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 26 <security mode="None"> 27 <transport clientCredentialType="None" proxyCredentialType="None" 28 realm="" /> 29 <message clientCredentialType="UserName" algorithmSuite="Default" /> 30 </security> 31 </binding> 32 <binding name="BasicHttpBinding_ISearch" closeTimeout="00:01:00" 33 openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" 34 allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" 35 maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" 36 messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" 37 useDefaultWebProxy="true"> 38 <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" 39 maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 40 <security mode="None"> 41 <transport clientCredentialType="None" proxyCredentialType="None" 42 realm="" /> 43 <message clientCredentialType="UserName" algorithmSuite="Default" /> 44 </security> 45 </binding> 46 <binding name="BasicHttpBinding_ISave" closeTimeout="00:01:00" 47 openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" 48 allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" 49 maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" 50 messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" 51 useDefaultWebProxy="true"> 52 <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" 53 maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 54 <security mode="None"> 55 <transport clientCredentialType="None" proxyCredentialType="None" 56 realm="" /> 57 <message clientCredentialType="UserName" algorithmSuite="Default" /> 58 </security> 59 </binding> 60 <binding name="BasicHttpBinding_IGet" closeTimeout="00:01:00" 61 openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" 62 allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" 63 maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" 64 messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" 65 useDefaultWebProxy="true"> 66 <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" 67 maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 68 <security mode="None"> 69 <transport clientCredentialType="None" proxyCredentialType="None" 70 realm="" /> 71 <message clientCredentialType="UserName" algorithmSuite="Default" /> 72 </security> 73 </binding> 74 </basicHttpBinding> 75 </bindings> 76 <client> 77 <endpoint address="http://localhost:8080/Add.svc" binding="basicHttpBinding" 78 bindingConfiguration="BasicHttpBinding_IAdd" contract="IAdd" 79 name="BasicHttpBinding_IAdd" /> 80 <endpoint address="http://localhost:8080/Remove.svc" binding="basicHttpBinding" 81 bindingConfiguration="BasicHttpBinding_IRemove" contract="IRemove" 82 name="BasicHttpBinding_IRemove" /> 83 <endpoint address="http://localhost:8080/Search.svc" binding="basicHttpBinding" 84 bindingConfiguration="BasicHttpBinding_ISearch" contract="ISearch" 85 name="BasicHttpBinding_ISearch" /> 86 <endpoint address="http://localhost:8080/Save.svc" binding="basicHttpBinding" 87 bindingConfiguration="BasicHttpBinding_ISave" contract="ISave" 88 name="BasicHttpBinding_ISave" /> 89 <endpoint address="http://localhost:8080/Get.svc" binding="basicHttpBinding" 90 bindingConfiguration="BasicHttpBinding_IGet" contract="IGet" 91 name="BasicHttpBinding_IGet" /> 92 </client> 93 </system.serviceModel>
