我做了一个与套接字聊天的应用程序：服务器为服务器创建一个套接字连接并等待来自任何客户端的消息：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Xml;
using System.Net.Sockets;
using System.Net;
using System.Threading;
using System.IO;
namespace server
{
public partial class Form1 : Form
{
public static byte[] data;
public static byte[] data1;
public static Socket sock;
public delegate void operation(string s);
public delegate void operation2();
public delegate bool verifier();
public Form1()
{
InitializeComponent();
sock = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
IPAddress adress = IPAddress.Parse("127.0.0.1");
IPEndPoint iep = new IPEndPoint(adress, 4000);
EndPoint ep = (EndPoint)iep;
sock.Bind(iep);
sock.Listen(10);
sock = sock.Accept();
data1 = new byte[1024];
data = new byte[1024];
Thread.Sleep(2000);
this.Show();
if (sock.Receive(data) > 0)
{
Thread t = new Thread(new ThreadStart(aller));
t.Start();
}
}
private void effectuer(String s)
{
textBox1.Text += "serveur: " + s + "\r\n";
message.Text = "";
}
private void effectuer4(String s)
{
textBox1.Text += "Client: " + s + "\r\n";
message.Text = "";
}
private void aller() {
String s = ASCIIEncoding.ASCII.GetString(data);
if (this.InvokeRequired) Invoke((operation)effectuer4, s);
else effectuer4(s);
//Thread.Sleep(2000);
byte[] data2 = new byte[1024];
if (sock.Receive(data2) > 0 && data2 != data)
{
data = data2;
Thread t = new Thread(new ThreadStart(aller));
t.Start();
}
}
private void buttonDisconnect_Click(object sender, EventArgs e)
{
sock.Close();
Application.Exit();
}
private void buttonSend_Click(object sender, EventArgs e)
{
String s = message.Text ;
data1 = System.Text.Encoding.ASCII.GetBytes(s);
sock.Send(data1);
Invoke((operation)effectuer, s);
}
}
}
对于客户端：他向服务器发送一个空消息并等待服务器的响应

if(this.InvokeRequired) Invoke((operation)effectuer4, s);
else effectuer4(s);
// Thread.Sleep(2000);

if (sock.Receive(data2) > 0 && data2 != data)
{
data = data2;
Thread t = new Thread(new ThreadStart(aller));
t.Start();
}
}
private void envoi()
{
String s = message.Text ;
data1 = System.Text.Encoding.ASCII.GetBytes(s);
sock.Send(data1);
effectuer(s);
}
private void effectuer(String s)
{
textBox1.Text += "client: " + s + "\r\n";
message.Text = "";
}
private void effectuer4(String s)
{
textBox1.Text += "Server: " + s + "\r\n";
message.Text = "";
}
private void buttonDisconnect_Click(object sender, EventArgs e)
{

}

sock.Send(data1);
Invoke((operation)effectuer, s);
}
}
}
我的问题是：我不会说服务器或客户端没有义务初始化应用程序，但两次可以这样做+当我将服务器作为控制台应用程序进行时，它可以工作，但是当我将服务器更改为类似应用程序的 winforms 时被屏蔽了！！！！！！所以我需要帮助
