我使用TcpListener和TcpClient在C＃中编写了服务器和客户端程序，我希望它们交换字符串。如果两台PC都连接到同一网络并且我使用服务器的本地地址，则可以使用，但是当PC连接到其他网络并且使用公共地址时，会出现以下错误：

Exception: System.Net.Sockets.SocketException (0x80004005): The requested address is not valid in its context
   at System.Net.Sockets.Socket.DoBind(EndPoint endPointSnapshot, SocketAddress socketAddress)
   at System.Net.Sockets.Socket.Bind(EndPoint localEP)
   at System.Net.Sockets.TcpListener.Start(Int32 backlog)
   at System.Net.Sockets.TcpListener.Start()
   at Server___Network_Class.Program.Main(String[] args) in D:\Server - Network Class\Program.cs:line 18

此错误涉及第18行，即myList.Start（）;。但我不知道为什么会引发此异常。我打开了路由器端口，并正确设置了Windows防火墙...这是我编写的服务器和客户端代码：

服务器

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;

namespace Server___Network_Class {
    class Program {
        static void Main(string[] args) {
            try {
                IPAddress ipAddress = IPAddress.Parse("146.241.31.193"); //That's the public IP

                //Initialize the listener
                TcpListener myList = new TcpListener(ipAddress, 51328);
                //Start listening the selected port
                myList.Start();

                
                Socket socket = myList.AcceptSocket();

                
                ASCIIEncoding asen = new ASCIIEncoding();
                socket.Send(asen.GetBytes("Can you read this?"));

                
                socket.Close();
                myList.Stop();

            }
            catch (Exception e) {
                Console.WriteLine("Exception: " + e);

            }

            Console.ReadKey();
        }
    }
}

客户

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;

namespace Client___Class_Network {
    class Program {
        static void Main(string[] args) {
            try {
                //Inizializzo il client
                TcpClient client = new TcpClient();

                //Cerco di connettermi al server
                client.Connect("146.241.31.193", 51328); //IP and Port i want to connect to
                
                //Stream sul quale inviare e ricevere i dati dal server
                NetworkStream stream = client.GetStream();

                Byte[] bytesRecived = new Byte[256];
                int totBytesRecived = stream.Read(bytesRecived, 0, bytesRecived.Length);
                String stringData = System.Text.Encoding.ASCII.GetString(bytesRecived, 0, totBytesRecived);


                Console.Write(stringData);

                client.Close();
            }

            catch (Exception e) {
                Console.WriteLine("Exception: " + e);
            }

            Console.ReadKey();
        }
    }
}

只有服务器程序会抛出该异常，客户端似乎是工作文件...

你能帮我解决这个问题吗？我（几乎）在网上搜索了所有内容，但找不到任何有用的答案。提前致谢！
