纯手写wcf代码，wcf入门，wcf基础教程

1、定义服务协定

    =>定义接口

using System.ServiceModel;

namespace WcfConsole
{
    /// <summary>
    /// 定义服务协定
    /// </summary>
    [ServiceContract]
    interface IW
    {
        [OperationContract]
        string HelloWorld();
    }
}

2、实现服务协定

    =>实现接口

namespace WcfConsole
{
    /// <summary>
    /// 实现服务协定
    /// </summary>
    public class W : IW
    {
        public string HelloWorld()
        {
            return "HelloWorld";
        }
    }
}

3、承载和执行服务

    =>打开服务

using System;
using System.ServiceModel;
using System.ServiceModel.Description;

namespace WcfConsole
{
    /// <summary>
    /// 承载和执行主要的 WCF 服务
    /// </summary>
    class Program
    {
        static void Main(string[] args)
        {
            //创建服务网址
            Uri url = new Uri("http://localhost:5210/W/");
            //创建server主机
            ServiceHost host = new ServiceHost(typeof(W), url);
            try
            {
                //加入服务端点
                host.AddServiceEndpoint(typeof(IW), new WSHttpBinding(), "serviceName");

                //启用元素交换
                ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
                smb.HttpGetEnabled = true;
                host.Description.Behaviors.Add(smb);

                //打开服务
                host.Open();

                Console.WriteLine("服务打开成功……");
                Console.ReadKey();

                //关闭服务
                host.Close();
            }
            catch (CommunicationException e)
            {
                Console.WriteLine(e.Message);
                //关闭服务
                host.Close();
            }
        }
    }
}

4、创建client

    =>须要先打开匃

    =>新建项目

    =>加入服务引用

5、配置client

    =>加入时微软自己主动配置

<?xml version="1.0" encoding="utf-8" ?
>
<configuration>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
  </startup>
  <system.serviceModel>
    <bindings>
      <wsHttpBinding>
        <binding name="WSHttpBinding_IW" />
      </wsHttpBinding>
    </bindings>
    <client>
      <!--指定用于调用服务时，端点-->
      <endpoint address="http://localhost:5210/W/serviceName" binding="wsHttpBinding"
            bindingConfiguration="WSHttpBinding_IW" contract="WService.IW"
            name="WSHttpBinding_IW">
        <identity>
          <userPrincipalName value="DUHUIFENG\liman" />
        </identity>
      </endpoint>
    </client>
  </system.serviceModel>
</configuration>

6、使用client

    =>

using System;
namespace ConsoleApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            WService.WClient w = new WService.WClient();
            string result = w.HelloWorld();
            Console.WriteLine(result);
            w.Close();

            Console.ReadKey();
        }
    }
}
