在 C# 套接字编程中使应用程序崩溃

Question

我用 C# winforms 编写了这段代码，但它在第 33 行崩溃，并且会被冻结并且没有响应。 我将所有代码放在按钮单击中，以便当我单击按钮时服务器运行并且客户端可以连接到该按钮。 如果您用您的解决方案解决这个问题，我会很高兴。

using System;
using System.Text;
using System.Windows.Forms;
using System.Net.Sockets;
using System.IO;
using System.Net;

namespace Server_SP
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Socket listenerr = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            IPAddress localAddress = IPAddress.Parse("127.0.0.1");
            IPEndPoint localEndpoint = new IPEndPoint(localAddress, 8575);
            listenerr.Bind(localEndpoint);

            IPAddress ipAddress = IPAddress.Parse("0.0.0.0");
            int port = 8575;
            TcpListener listener = new TcpListener(ipAddress, port);
            listener.Start();
            label2.Text = "Serving on Port 8587";
            while (true)
            {
                label1.Text = " Waiting for connection...";
                TcpClient cliend = listener.AcceptTcpClient();
                label1.Text = "Client Accepted";
                NetworkStream stream = cliend.GetStream();
                StreamReader sr = new StreamReader(cliend.GetStream());
                StreamWriter sw = new StreamWriter(cliend.GetStream());
                try
                {
                    byte[] buffer = new byte[1024];
                    stream.Read(buffer, 0, buffer.Length);
                    int count = 0;
                    //////how many bytes
                    foreach (byte b in buffer)
                    {
                        if (b!=0)
                        {
                            count++;
                        }
                    }
                    string reced = Encoding.UTF8.GetString(buffer, 0, count);
                    label3.Text = "Request Reced: " + reced;
                    sw.WriteLine("Hiiii.I am serverrr");
                    sw.Flush();
                }
                catch (Exception errorr)
                {
                    label1.Text = "Errorrrr";
                    sw.WriteLine(errorr.ToString());

                }
            }
        }
    }
}

我删除了 while 循环，并用下面的代码替换了第 41 行，但没有帮助。

TcpClient cliend = listenerr.AcceptTcpClient(); 

实际上，我在控制台中正确完成了这项工作并且可以正常工作，但是当我尝试将该代码移植到 Windows 应用程序时，我遇到了这些问题。

看来你需要将服务器代码移至单独的线程以避免像这样阻塞UI

private void button1_Click(object sender, EventArgs e)
{
    await Task.Run(()=>HandleServer());
}
    
private void HandleServer()
{
    // do your stuff run the server and also the while loop
}
