C#网络编程造成UI卡死的问题

[Tony_Xian]

服务端代码如下

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Net.Sockets;
using System.Net;
using System.Threading.Tasks;

namespace WindowsFormsApplication6
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        TcpListener listen;
        NetworkStream netstream;
        private async void button1_Click(object sender, EventArgs e)
        {
            listen = new TcpListener(9999);
            listen.Start();
            await Task.Delay(0);
            listBox1.Items.Add("服务器启动");
            Socket socket = listen.AcceptSocket();
            netstream = new NetworkStream(socket);
        }

        private void button2_Click(object sender, EventArgs e)
        {
            if (netstream.DataAvailable)
            {
                byte[] getdata = new byte[1024];
                int length = netstream.Read(getdata, 0, getdata.Length);
                string msg = Encoding.Default.GetString(getdata, 0, getdata.Length);
                listBox1.Items.Add("收到客户端消息");
                listBox1.Items.Add(msg);
            }
        }
    }
}

当按下启动时，服务端开始监听，画面会卡死动不了，除非客户端发送消息过来，请问怎样解决?就是在监听的过程中UI不卡死

首先不谈你代码或者逻辑的合理性，单看你的问题，解决UI卡死

listen = new TcpListener(9999);
            listen.Start();
            await Task.Delay(0);
            listBox1.Items.Add("服务器启动");

            new Task(delegate
            {
                Socket socket = listen.AcceptSocket();
                netstream = new NetworkStream(socket);
            }).Start();
