我遇到的问题是，我保持获取异常“尝试启动服务器上的TcpListener时，通常只允许每个套接字地址(协议/网络地址/端口)的一个用法。

我试过禁用我的防火墙，更改要使用的端口，移动变量但无济于事(客户端正常工作，但显然无法找到服务器，因为我无法启动它)。

我见过描述使用Socket.Poll()的解决方案，但由于我只使用TcpListener对象，我不知道如何使用Poll函数。

我的代码：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Net.Sockets;

using System.Net;

using System.Threading;

using System.Text;

namespace ServerTutorial {

class Server {

private readonly Thread m_listenThread;

public Server() {

m_listenThread = new Thread(new ThreadStart(ListenForClients));

m_listenThread.Start();

}

public void ListenForClients() {

var listener = new TcpListener(IPAddress.Any, 3000);

listener.Start();

while (true) {

//Blocks until a client has connected to the server

TcpClient client = listener.AcceptTcpClient();

//Send a message to the client

var encoder = new ASCIIEncoding();

NetworkStream clientStream = client.GetStream();

byte[] buffer = encoder.GetBytes("Hello Client!");

clientStream.Write(buffer, 0, buffer.Length);

clientStream.Flush();

//Create a thread to handle communication with the connected client

var clientThread = new Thread(new ParameterizedThreadStart(HandleClient));

clientThread.Start(client);

}

}

private void HandleClient(object clientObj) { //Param thread start can only accept object types, hence the cast

var client = (TcpClient) clientObj;

NetworkStream clientStream = client.GetStream();

var message = new byte[4096];

while (true) {

int bytesRead = 0;

try {

//Block until a client sends a message

bytesRead = clientStream.Read(message, 0, 4096);

} catch {

//A socket error has occurred

System.Diagnostics.Debug.WriteLine("A socket error has occured");

break;

}

if (bytesRead == 0) {

//The client has disconnected from the server

System.Diagnostics.Debug.WriteLine("A client has disconnected from the server");

client.Close();

break;

}

//Message has been received

var encoder = new ASCIIEncoding();

System.Diagnostics.Debug.WriteLine(encoder.GetString(message, 0, bytesRead));

}

}

}

}

在我的主要方法：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace ServerTutorial {

class Program {

static void Main(string[] args) {

var server = new Server();

server.ListenForClients();

}

}

}

任何帮助，非常感激！

注意''mingw-w64'你需要'closesocket()'而不是'close()'来释放端口。 –
