1. 打开上一个项目

2. 修改Program.cs, 注意注释掉的绿色部分，因为我们使用配置文件公布EndPoint

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using JackWangWCFService;
using System.ServiceModel;
namespace JackWangServiceHost
{
    class Program
    {
        static void Main(string[] args)
        {
            using (ServiceHost host=new ServiceHost(typeof(JackWangWCFService.Calc)))
            {
                //host.AddServiceEndpoint(typeof(JackWangWCFService.ICalc), 
                //    new NetTcpBinding(), "net.tcp://localhost:9000/Add");
                host.Open();
                Console.Out.WriteLine("calc web service started at:"+DateTime.Now.ToString());
                Console.ReadLine();
            }
        }
    }
}
 
3.添加一个App.Config文件,注意Service 的name是实现服务的类，客户端访问的地址是http://localhost:9000/Add
 
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="JackWangWCFService.Calc" behaviorConfiguration="serviceBehavior">
        <endpoint  binding="basicHttpBinding"  contract="JackWangWCFService.ICalc" address="Add"></endpoint>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:9000"/>
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="serviceBehavior">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>        
    </behaviors>
  </system.serviceModel>
</configuration> 
 
 
4.修改客户端的代码,注意这次使用的是http的传输方式
 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
namespace JackWangServiceClient
{
    [ServiceContract]
    public interface ICalc
    {
        [OperationContract]
        long Add(int a, int b);
    }
    class Program
    {
        static void Main(string[] args)
        {
            ICalc proxy = ChannelFactory<ICalc>.CreateChannel(new BasicHttpBinding(),
                new EndpointAddress("http://localhost:9000/Add"));
            long result = proxy.Add(50, 60);
            Console.Out.WriteLine("result from server is:" + result);
            Console.ReadLine();
        }
    }
}
