WCF基础(1)

1.WCF服务自承载

[ServiceContract(Namespace = "www.matriax.com")]
    public interface IWCFService
    {
        [OperationContract]
        string Hello(string name);
    }

    public class WCFService : IWCFService
    {
        public string Hello(string name)
        {
            return String.Format("hello {0}", name);
        }
    }

using (ServiceHost host = new ServiceHost(typeof(WCFService)))
 {
          //经过这个endpoint的消息，都有IWCFService这个服务进行处理.注意：这个并没有公布元数据终结点
          //但是客户端还是可以访问。原因是客户端已经知道服务的结构，不需要从元数据终结点下载服务结构
                
           //通过代码绑定终结点
           host.AddServiceEndpoint(typeof(IWCFService), new NetTcpBinding(), "net.tcp://localhost:8081/WCFService");
               
           //参考配置文件
           host.Open();
                
}

服务端使用配置  

  <system.serviceModel>
    <services>
      <service name="WCFServices.WCFService" behaviorConfiguration="servicebehavior">
        <endpoint address="WCFService" binding="basicHttpBinding" contract="WCFServices.IWCFService"></endpoint>
        <!--元数据交换特定绑定方式，以及内建的元数据交换接口-->
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"></endpoint>
        <host>
          <baseAddresses >
            <add baseAddress=">
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="servicebehavior">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

2.客户端

使用代码创建代理

首先要将服务契约结构公布到客户端

[ServiceContract(Namespace = "

www.matriax.com")]
    public interface IWCFService
    {
        [OperationContract]
        string Hello(string name);
    }

通过通道工厂创建代理

//首先需要了解服务的结构。需要将服务接口告知到client

 IWCFService proxy = ChannelFactory<IWCFService>.CreateChannel(new NetTcpBinding(), new EndpointAddress("net.tcp://localhost:8080/WCFService"));

另一种直接添加服务引用或使用命令创建客户端
