当我尝试关闭表单

时，我遇到问题

当我运行服务器时并且线程启动套接字等待接受然后我打开服务器我尝试关闭服务器这不可以，它堆叠在NewCon.Abort（）;

中请帮助我

代码是：

 private void ServerOn_Click(object sender, EventArgs e)
    {
        sckServerSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        sckServerSocket.Bind(new IPEndPoint(ip, port));
        sckServerSocket.Listen(0);
        bIsOn = true;
        dicStudent = new Dictionary<Socket, Student>();
        NewCon = new Thread(getNewConnection);
        NewCon.Start();
    }

    public void getNewConnection()
    {
        while (true)
        {
                Socket sckReciveConnect = sckServerSocket.Accept();
                dicStudent.Add(sckReciveConnect, new Student(sckReciveConnect, this));
        }
    }

 private void ServerOut_FormClosing(object sender, FormClosingEventArgs e)
    {
        if (bIsOn)
        {
            try
            {
              --->  NewCon.Abort();
                sckServerSocket.Close();

                foreach (Student stu in dicStudent.Values)
                {
                    byte[] Close = Encoding.Default.GetBytes("EXT");
                    stu.scksReciveSocket.Send(Close, 0, Close.Length, 0);
                }

                this.Close();
            }
            catch  (Exception x)
            {
                MessageBox.Show(x.Message);
            }
        }
    }

不要试图杀死线程。只需针对服务器调用Close()，这将导致阻止Accept()调用退出并出现异常：

// NewCon.Abort(); <-- don't do this
sckServerSocket.Close(); // just close it

你可以捕获它并突破你的循环：

    public void getNewConnection()
    {
        while (true)
        {
            try
            {
                Socket sckReciveConnect = sckServerSocket.Accept();
                // ...
            }
            catch (Exception)
            {
                return; // drop out of loop
            }
        }
    }
