一个简单的WCF程序创建过程

1.创建一个空白的解决方案.

2.创建服务主机
  创建WEB宿主做服务主机,用来侦听客户端提交的请求,并创建用于处理那些请求的服务类的实例.

<1>代码掩藏文件方式的服务类.
   创建成功后如下图所示意.

在App_Code下含有一个带事例代码的Service.cs文件.(本过程直接采用现有代码).Service.svc文件相当于WebService的.asmx(本过程此处不做修改).在Web.config中添加一行

1<serviceMetadata httpGetEnabled="true"/>

完整的Web.config文件内容如下.

 1<?xml version="1.0"?>
 2<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
 3  <system.serviceModel>
 4    <services>
 5      <!-- Before deployment, you should remove the returnFaults behavior configuration to avoid disclosing information in exception messages -->
 6      <service name="WCFServiceLibrary.service1" behaviorConfiguration="returnFaults">
 7                <endpoint contract="WCFServiceLibrary.IService1" binding="wsHttpBinding"/>
 8      </service>
 9    </services>
10    <behaviors>
11      <serviceBehaviors>
12        <behavior name="returnFaults" >
13          <serviceDebug includeExceptionDetailInFaults="true" />
14          <serviceMetadata httpGetEnabled="true" />
15        </behavior>
16      </serviceBehaviors>
17    </behaviors>
18  </system.serviceModel>
19  <system.web>
20    <compilation debug="true"/>
21  </system.web>
22</configuration>

<2>引用预编译程序集的服务类.

添加对服务类的引用.

采用此种方式,可以删除App_Code下的Service.cs文件.修改Service.svc文件内容如下:

1<% @ServiceHost Language=C# Debug="true" Service="WCFServiceLibrary.service1" %>

同时Web.confing同步修改如下:

 1<?xml version="1.0"?>
 2<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
 3    <system.serviceModel>
 4        <services>
 5            <!-- Before deployment, you should remove the returnFaults behavior configuration to avoid disclosing information in exception messages -->
 6            <service name="WCFServiceLibrary.service1" behaviorConfiguration="returnFaults">
 7                <endpoint contract="WCFServiceLibrary.IService1" binding="wsHttpBinding"/>
 8            </service>
 9        </services>
10        <behaviors>
11            <serviceBehaviors>
12                <behavior name="returnFaults">
13                    <serviceDebug includeExceptionDetailInFaults="true"/>
14                    <serviceMetadata httpGetEnabled="true"/>
15                </behavior>
16            </serviceBehaviors>
17        </behaviors>
18    </system.serviceModel>
19    <system.web>
20        <compilation debug="true">
21            <assemblies>
22                <add assembly="System.Security, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
23                <add assembly="Microsoft.Transactions.Bridge, Version=3.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
24                <add assembly="SMDiagnostics, Version=3.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
25                <add assembly="System.IdentityModel.Selectors, Version=3.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
26                <add assembly="System.DirectoryServices, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
27                <add assembly="System.Web.RegularExpressions, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
28                <add assembly="System.Transactions, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
29                <add assembly="System.Messaging, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
30                <add assembly="System.ServiceProcess, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/></assemblies></compilation>
31    </system.web>
32</configuration>

3.客户端配置和实现.
 创建控制台程序作为测试客户端程序.
 
 添加服务引用后如下.
 
客户端做简单的如下编程.

 1using System;
 2using System.Collections.Generic;
 3using System.Text; 
 4
 5namespace WCFCon
 6{
 7    class Program
 8    {
 9        static void Main(string[] args)
10        {
11            localhost.MyServiceClient wcf = new WCFCon.localhost.MyServiceClient();
12            Console.WriteLine("请输入数据:");
13            string str = Console.ReadLine();
14            Console.WriteLine("你输入的数据是:{0}", wcf.MyOperation1(str));
15            localhost.DataContract1 da = new WCFCon.localhost.DataContract1();
16            Console.WriteLine("请输入FirstName:");
17            da.FirstName = Console.ReadLine();
18            Console.WriteLine("请输入LastName:");
19            da.LastName = Console.ReadLine();
20            Console.WriteLine("FirstName+LastName={0}", wcf.MyOperation2(da));
21        }
22    }
23}

运行结果输出如下.

至此,一个简单的WCF创建演示过程结束.其它详细请参阅MSDN.
