wcf 学习1：搭建服务

一：创建一个解决方案

1：分别添加：控制台应用程序：Hosting（宿主）、控制台应用程序：Client（客户端）、类库：Service （服务）、类库：Contract（契约）

2：添加契约：

右击contract项目，添加接口 ICalcultor

 
[ServiceContract(Name = "CalcultorService", Namespace = "http://www.artech.com")]  注意：http://www.artech.com   不能写成 http://www.artech.com/            
    public interface ICalculator
    {
        [OperationContract]
        double Add(double x, double y);
        [OperationContract]
        double Subtract(double x, double y);
        [OperationContract]
        double Multiply(double x, double y);
        [OperationContract]
        double Divide(double x, double y);
    }

　　3：添加服务

右击Service项目，添加类：Calcutor

public class CalcultorService : ICalculator
    {
        public double Add(double x, double y)
        {
            return x + y;
        }

        public double Subtract(double x, double y)
        {
            return x - y;
        }

        public double Multiply(double x, double y)
        {
            return x * y;
        }

        public double Divide(double x, double y)
        {
            return x / y;
        }
    }

　　

4：配置Hosting（宿主）

编程方式配置：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.ServiceModel.Description;
using WCFContract;
using WCFService;
namespace Host3_26
{
    class Program
    {
        static void Main(string[] args)
        {
            using (ServiceHost host = new ServiceHost(typeof(CalcultorService)))
            {
                host.AddServiceEndpoint(typeof(ICalculator), new WSHttpBinding(), "http://127.0.0.1:9999/CalcultorService");
                if (host.Description.Behaviors.Find<ServiceMetadataBehavior>() == null)
                {
                    ServiceMetadataBehavior behavior = new ServiceMetadataBehavior();
                    behavior.HttpGetEnabled = true;
                    behavior.HttpGetUrl = new Uri("http://127.0.0.1:9999/CalcultorService/metadata");
                    host.Description.Behaviors.Add(behavior);
                }
                host.Opened += delegate
                {
                    Console.WriteLine("CalcultorService已经启动，按任意键终止服务！！");
                };
                host.Open();
                Console.Read();
            }
        }
    }
}

　　管理方式配置宿主：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="metadataBehavior">
          <serviceMetadata httpGetEnabled="true"  httpGetUrl="http://127.0.0.1:9999/CalcultorService/metadata"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service name="WCFService.CalcultorService" behaviorConfiguration="metadataBehavior">
        <endpoint address="http://127.0.0.1:9999/CalcultorService"
                  binding="wsHttpBinding"
                  contract="WCFContract.ICalculator"/>
      </service>
    </services>
  </system.serviceModel>
</configuration>

　　5:发布宿主

6：客户端添加服务

在宿主已经运行的情况下，右击客户端添加服务，路径：

http://127.0.0.1:9999/CalcultorService/metadata

cs代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Client3_26.ServiceReference1;

namespace Client3_26
{
    class Program
    {
        static void Main(string[] args)
        {
            using (CalcultorServiceClient pro = new CalcultorServiceClient())
            {
                Console.WriteLine(pro.Add(1, 1));
                Console.Read();
            }

        }
    }
}

　

//客户端调用服务方法2：
1：引用契约 using WCFContract;
2:修改配置文件：
       <endpoint address="http://127.0.0.1:9999/CalcultorService" 
 　　　　　　　　　binding="wsHttpBinding" 
　　　　　　　　　 contract="WCFContract.ICalculator"
　　　　　　　　　 name="defaultEndpoint"></endpoint>
3：开始调用
using (ChannelFactory<WCFContract.ICalculator> channe = new ChannelFactory<WCFContract.ICalculator>("defaultEndpoint"))
{
　　　　　　　　　　WCFContract.ICalculator ca = channe.CreateChannel();
　　　　　　　　　　Console.WriteLine(ca.Add(1, 2));
};
