c# - RemoteEndPoint 与 LocalEndPoint

Question

作为 C# 网络的初学者，我编写了一个简单的客户端-服务器应用程序。我正在连接到服务器正在监听的本地 IP 地址和端口 8080。

在客户端:

        IPAddress remoteaddr = IPAddress.Parse("127.0.0.1");
        int port = 8880;
        TcpClient tcpclient = new TcpClient();
        tcpclient.Connect(remoteaddr, port);
        NetworkStream networkstream = tcpclient.GetStream();

        IPEndPoint RemAddr = (IPEndPoint)tcpclient.Client.RemoteEndPoint;
        IPEndPoint LocAddr = (IPEndPoint)tcpclient.Client.LocalEndPoint;

        if (RemAddr != null)
        {
            // Using the RemoteEndPoint property.
            Console.WriteLine("I am connected to " + RemAddr.Address + "on port number " + RemAddr.Port);
        }

        if (LocAddr != null)
        {
            // Using the LocalEndPoint property.
            Console.WriteLine("My local IpAddress is :" + LocAddr.Address + "I am connected on port number " + LocAddr.Port);
        }

输出是:

I am connected to 127.0.0.1 on port number 8880
My local IpAddress is :127.0.0.1 I am connected on port number 46715

那么 RemoteEndPoint 和 LocalEndPoint 有什么区别呢？ LocalEndPoint 端口(在我的示例中为 46715)有什么用，它来自哪里？谢谢。

远程端点将向您显示哪个客户端 (ip) 连接到您的本地端点(更有可能是服务器 ip 127.0.0.1)
