如何以编程方式编写端点(netPeerTcpBinding)

Question

我需要在c#中以编程方式编写这个端点，这是一个聊天应用程序。

app.config部件

 <system.serviceModel>
        <client>
          <endpoint name="ChatEndPoint" address="net.p2p://chatMesh/ChatServer" binding="netPeerTcpBinding" bindingConfiguration="PeerTcpConfig" contract="Test.IChatService"></endpoint>
        </client>
        <bindings>
          <netPeerTcpBinding>
            <binding name="PeerTcpConfig" port="0">
              <security mode="None"></security>
              <resolver mode="Custom">
                <custom address="net.tcp://192.168.0.147:22222/ChatServer" binding="netTcpBinding" bindingConfiguration="TcpConfig"></custom>
              </resolver>
            </binding>
            <!--<binding name="BindingDefault" port="0">
              <security mode="None"></security>
              <resolver mode="Auto"></resolver>
            </binding>-->
          </netPeerTcpBinding>
          <netTcpBinding>
            <binding name="TcpConfig">
              <security mode="None"></security>
            </binding>
          </netTcpBinding>
        </bindings>
      </system.serviceModel>

C#部件

 InstanceContext context = new InstanceContext(
                        new Home(txtUserName.Text.Trim()));
                    factory =
                        new DuplexChannelFactory<IChatChannel>(context, "ChatEndPoint");
                    channel = factory.CreateChannel();

这对我来说工作得很好。但是，我需要动态更改端点地址。寻找有价值的支持。

使用端点选择逻辑编写您自己的ChanelFactory

或者只需使用另一个接受EndPointAddress对象的DuplexChanelFactory构造函数，您可以在代码中使用所有必要的参数创建该对象
