c# - C# configuring TCPClient client's port

Question

I have coded TCPClient() in C# to communicate with another device on LAN. I only have to specify the target IP and port number.

Now I am coding something quite similar to it. However, it specifies that the client port from my PC has to be something greater than 1024. How can I configure that? does this mean that VS automatically takes care of that if not specified?

Answer 1

TcpClient(IPEndPoint)可用于指定客户端端口（仅IPAddress.Any用于地址部分）。如Socket.Bind和wikipedia:ephemeral_port中所述，默认情况下将使用高于 1024 的端口。
