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());
             Response.End();
         }
     }
 }

结果是可喜的。
