【问题描述】：

现在在客户端 app.config 中：

<system.serviceModel>
    <client>
      <endpoint name="FileEndPoint" address="net.p2p://ChangingName123/FileServer"
                binding="netPeerTcpBinding" bindingConfiguration="PeerTcpConfig"
                contract="FileClient.IFileService"></endpoint>
     
      
   </client>

    <bindings>
      <netPeerTcpBinding>
        <binding name="PeerTcpConfig" port="0">
          <security mode="None"></security>
          <resolver mode="Custom">
            <custom address="net.tcp://191.14.3.11/FileServer" binding="netTcpBinding"
                    bindingConfiguration="TcpConfig"></custom>
          </resolver>
        </binding>
        
      </netPeerTcpBinding>
      <netTcpBinding>
        <binding name="TcpConfig">
          <security mode="None"></security>
        </binding>
      </netTcpBinding>
    </bindings>
  </system.serviceModel>

在客户端代码中：

InstanceContext context = new InstanceContext(
                        new ChatClient(numberclient);
DuplexChannelFactory<IFileChannel> factory =
                        new DuplexChannelFactory<IFileChannel>(context, "FileEndPoint");
IFileChannel channel = factory.CreateChannel();
                                        
channel.Open();

我尝试这样做：

NetPeerTcpBinding binding = new NetPeerTcpBinding();
            
EndpointAddress endpoint = new EndpointAddress("net.p2p://ChangingName123/FileServer");

InstanceContext context = new InstanceContext(
                        new ChatClient(numberclient);
DuplexChannelFactory<IFileChannel> factory =
                        new DuplexChannelFactory<IFileChannel>(context, binding, endpoint);

但“PeerTcpConfig”有custom address="net.tcp://191.14.3.11/FileServer" 和bindingConfiguration="TcpConfig"

如何在代码中设置绑定自定义地址并为 NetPeerTcpBinding 绑定设置一个绑定 TcpConfig

【问题讨论】：

可以参考：docs.microsoft.com/en-us/dotnet/framework/wcf/samples/…
本文中的 app.config 中有多个端点，但需要示例如何在代码中生成以及在代码中询问您可以看到一个端点的多个绑定
先在ru讨论中发布这个问题，找到解决方案here

【解决方案1】：

  private NetTcpBinding binding = new NetTcpBinding();
  private EndpointAddress endPoint;

  private void initial_binding()
    {
        binding.Security.Mode = SecurityMode.None;
        
        binding.HostNameComparisonMode = HostNameComparisonMode.WeakWildcard;
       
        binding.ReliableSession.Enabled = false;
    }

initial_binding();
endPoint= new EndpointAddress(@"net.tcp://" + 191.14.3.11+ @":4000/FileServer");


 var IAChannelFactory = new ChannelFactory<FileClient.IFileService>(binding, 
 endpoint);
            IFileService Client = new FileService();
            try
             {
                client.anyFunction();
             }
            catch (Exception ex)
             {
                Logger.Log.Error(ex.Message);
             }

第一步，您应该定义 netTcpBinding 和一个端点，然后在这些简单地创建 ChannelFactory 对象并连接到您的服务之后分配您的自定义绑定和您的端点（您应该使用一个端口连接到您的端点）。这段代码在我的项目中工作了一年，我只是根据你的代码自定义它。如果您有任何问题，请尽管问。

【解决方案2】：

完成工作代码：

InstanceContext context = new InstanceContext(new ChatClient(numberclient));
NetPeerTcpBinding binding = new NetPeerTcpBinding();

EndpointAddress endpoint = new EndpointAddress("net.p2p://ChangingName123/FileServer");
binding.Resolver.Custom.Address = new EndpointAddress("net.tcp://191.14.3.11/FileServer");
binding.Security.Mode = SecurityMode.None;
NetTcpBinding ntcp = new NetTcpBinding();
ntcp.Security.Mode = SecurityMode.None;
binding.Resolver.Custom.Binding = ntcp;
factory = new DuplexChannelFactory<IChatChannel>(context, binding, endpoint);
channel = factory.CreateChannel();
