WCF服务寄宿应用程序

1.先创建一个WCF服务库

 

 2.创建一个Console控制台，服务将寄宿在该应用程序上，该程序一旦关闭，服务将停止。

控制台代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using WcfServiceLibrary;
using System.ServiceModel;
using System.ServiceModel.Description;

namespace wcfConsole
{
    class Program
    {
        static void Main(string[] args)
        {
            //这是将来要引用的服务地址，由你自己定义
            Uri address = new Uri("http://localhost:8123/ServiceDemo/Service");

            //MyService是你WCF服务库里面服务的名称
            ServiceHost selfHost = new ServiceHost(typeof(MyService), address);

            try
            {
                //IService是你服务库里面接口的名称
                selfHost.AddServiceEndpoint(typeof(IService), new WSHttpBinding(), "MyService");

                //设置服务行为
                ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
                smb.HttpGetEnabled = true;
                selfHost.Description.Behaviors.Add(smb);

                //打开 ServiceHost
                selfHost.Open();
                Console.WriteLine("success");
                Console.WriteLine();
                Console.ReadLine();

                // 关闭 ServiceHost
                selfHost.Close();
            }
            catch (CommunicationException ce)
            {
                Console.WriteLine("Error : {0}", ce.Message);
                selfHost.Abort();
            }
        }
    }
}

也可以用 app.config 配置服务信息，代码要略作修改。
app.config内容：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <services>
            <service name="WcfServiceLibrary.MyService" behaviorConfiguration="MyBehavior">
                <host>
                    <baseAddresses>
                        <add baseAddress="http://localhost:8123/ServiceDemo/Service" />
                    </baseAddresses>
                </host>
                <endpoint address="MyService" binding="basicHttpBinding"
                 contract="WcfServiceLibrary.IService"  />
            </service>
        </services>
        <behaviors>
            <serviceBehaviors>
                <behavior name="MyBehavior">
                    <serviceMetadata httpGetEnabled="true" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
    </system.serviceModel>
</configuration>

service.name 是你WCF服务库里服务类的完全限定名

service.behaviorConfiguration 要与 behavior.name 相同

endpoint.contract 是你WCF服务库里接口的完全限定名

 改动后的控制台代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using WcfServiceLibrary;
using System.ServiceModel;
using System.ServiceModel.Description;

namespace wcfConsole
{
    class Program
    {
        static void Main(string[] args)
        {
            //这是将来要引用的服务地址，由你自己定义
            //Uri address = new Uri("http://localhost:8123/ServiceDemo/Service");

            //MyService是你WCF服务库里面服务的名称
            ServiceHost selfHost = new ServiceHost(typeof(MyService));

            try
            {
                ////IService是你服务库里面接口的名称
                //selfHost.AddServiceEndpoint(typeof(IService), new WSHttpBinding(), "MyService");

                ////设置服务行为
                //ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
                //smb.HttpGetEnabled = true;
                //selfHost.Description.Behaviors.Add(smb);

                //打开 ServiceHost
                selfHost.Open();
                Console.WriteLine("success");
                Console.WriteLine();
                Console.ReadLine();

                // 关闭 ServiceHost
                selfHost.Close();
            }
            catch (CommunicationException ce)
            {
                Console.WriteLine("Error : {0}", ce.Message);
                selfHost.Abort();
            }
        }
    }
}

 测试：

先运行控制台，然后新建项目添加服务引用：http://localhost:8123/ServiceDemo/Service

直接调用WCF服务库默认提供的方法：GetData()

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;


namespace InvokeWcfServiceTest
{
    public partial class _default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            ServiceReference.ServiceClient client = new ServiceReference.ServiceClient();
            Response.Write(client.GetData(123789));
            Response.End();
        }
    }
}

结果是可喜的。
