如何为WCF编写基于套接字的自定义传输

public class CustomSocketTransportChannel : IDuplexSessionChannel
{
    // 实现 IDuplexSessionChannel 接口的方法和属性
}

public class CustomSocketTransportBinding : Binding
{
    // 实现 Binding 类的方法和属性
}

public class CustomSocketTransportChannel : IDuplexSessionChannel
{
    private Socket _socket;

    // 实现 IDuplexSessionChannel 接口的方法和属性

    public IAsyncResult BeginReceive(TimeSpan timeout, AsyncCallback callback, object state)
    {
        // 使用套接字接收数据
    }

    public IAsyncResult BeginSend(Message message, TimeSpan timeout, AsyncCallback callback, object state)
    {
        // 使用套接字发送数据
    }
}

 <system.serviceModel>
    <bindings>
     <customBinding>
       <binding name="CustomSocketTransport">
         <customSocketTransport />
        </binding>
      </customBinding>
    </bindings>
   <services>
     <service name="MyService">
       <endpoint address="soap.tcp://localhost:8080" binding="customBinding" bindingConfiguration="CustomSocketTransport" contract="IMyService" />
      </service>
    </services>
   <client>
     <endpoint address="soap.tcp://localhost:8080" binding="customBinding" bindingConfiguration="CustomSocketTransport" contract="IMyService" />
    </client>
  </system.serviceModel>
</configuration>
