.net - 如何在 .NET 中释放端口....在 TCPListener 从远程客户端收到所需内容后

Question

如何释放 TCPListener 使用的 .NET 中的端口......在 TCPListener 收到所需的东西之后

Answer 1

Just call the Stop-method on the TcpListener.

Answer 2

我们首先建立了第一个Socket：

     Socket socket1; 
     IPEndPoint localEP = new IPEndPoint (IPAddress.Any, 20000); 
     Socket1 = new Socket (AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); 
     Socket1.Bind (localEP); 

然后是第二个套接字：

     Socket socket2 
     IPEndPoint localEP = new IPEndPoint (IPAddress.Any, 20000); 
     Socket2 = new Socket (AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); 
     Socket2.SetSocketOption (SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true); 
    / / Please note this one. True ReuseAddress options will be set to allow the socket to bind already in use in the address. 
     Socket2.Bind (localEP); 

这样就将 Socket1 和 Socket2 捆绑在同一个端口上了。
