C# 在WinForms中创建用于聊天的客户端应用程序

我正在尝试用C#，WinForms创建简单的聊天

        TcpClient client;
        public MainWindow()
        {
          InitializeComponent();
          client = new TcpClient("192.168.0.100", 1234);
          AppDomain.CurrentDomain.ProcessExit += new EventHandler(OnProcessExit);
          ReadAsync(client,logbox);
        }

    private void sendButton_Click(object sender, EventArgs e)
            {
        string text = textBox.Text;
        byte[] data = Encoding.ASCII.GetBytes(text);
        NetworkStream stream  = client.GetStream();
        stream.Write(data,0,text.Length);
    }
    static async void ReadAsync(TcpClient client, RichTextBox box)
    {
        NetworkStream stream = client.GetStream();
        byte[] buffer = new byte[1024];
        while (true)
        {
            await stream.ReadAsync(buffer, 0, 1024);
            box.AppendText(Encoding.ASCII.GetString(buffer));
        }
    }
    private void MainWindow_Load(object sender, EventArgs e)
    {

    }
    void OnProcessExit(object sender, EventArgs e)
    {
        client.Close();
    }

我有问题，发送按钮点击，发送功能不工作。

我想，它在等着小溪。关闭（）；发送数据，但我需要此流来接收数据。

您应该使用套接字，这是一个简单的聊天winforms示例：

服务器：

using System;
using System.Threading;
using System.Net.Sockets;
using System.Text;
using System.Collections;

namespace ChatServer
{
    class Program
    {
        public static Hashtable clientsList = new Hashtable();

        static void Main(string[] args)
        {
            TcpListener serverSocket = new TcpListener(8888);
            TcpClient clientSocket = default(TcpClient);
            int counter = 0;

            serverSocket.Start();
            Console.WriteLine("Chat Server Started ....");
            counter = 0;
            while ((true))
            {
                counter += 1;
                clientSocket = serverSocket.AcceptTcpClient();

                byte[] bytesFrom = new byte[1000025];
                string dataFromClient = null;

                NetworkStream networkStream = clientSocket.GetStream();
                networkStream.Read(bytesFrom, 0, (int)clientSocket.ReceiveBufferSize);
                dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom);
                dataFromClient = dataFromClient.Substring(0, dataFromClient.IndexOf("$"));

                clientsList.Add(dataFromClient, clientSocket);

                broadcast(dataFromClient + " Joined ", dataFromClient, false);

                Console.WriteLine(dataFromClient + " Joined chat room ");
                handleClinet client = new handleClinet();
                client.startClient(clientSocket, dataFromClient, clientsList);
            }

            clientSocket.Close();
            serverSocket.Stop();
            Console.WriteLine("exit");
            Console.ReadLine();
        }

        public static void broadcast(string msg, string uName, bool flag)
        {
            foreach (DictionaryEntry Item in clientsList)
            {
                TcpClient broadcastSocket;
                broadcastSocket = (TcpClient)Item.Value;
                NetworkStream broadcastStream = broadcastSocket.GetStream();
                Byte[] broadcastBytes = null;

                if (flag == true)
                {
                    broadcastBytes = Encoding.ASCII.GetBytes(uName + " says : " + msg);
                }
                else
                {
                    broadcastBytes = Encoding.ASCII.GetBytes(msg);
                }

                broadcastStream.Write(broadcastBytes, 0, broadcastBytes.Length);
                broadcastStream.Flush();
            }
        } 
    }


    public class handleClinet
    {
        TcpClient clientSocket;
        string clNo;
        Hashtable clientsList;

        public void startClient(TcpClient inClientSocket, string clineNo, Hashtable cList)
        {
            this.clientSocket = inClientSocket;
            this.clNo = clineNo;
            this.clientsList = cList;
            Thread ctThread = new Thread(doChat);
            ctThread.Start();
        }

        private void doChat()
        {
            int requestCount = 0;
            byte[] bytesFrom = new byte[100025];
            string dataFromClient = null;
            Byte[] sendBytes = null;
            string serverResponse = null;
            string rCount = null;
            requestCount = 0;

            while ((true))
            {
                try
                {

                    dataFromClient = dataFromClient.Substring(0, dataFromClient.IndexOf("$"));
                    Console.WriteLine("From client - " + clNo + " : " + dataFromClient);
                    rCount = Convert.ToString(requestCount);

                    Program.broadcast(dataFromClient, clNo, true);
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.ToString());
                }
            }//end while

这会引发异常吗？上面的代码没有明显的错误。所以不管你有什么问题，都是你没有分享的代码。你的问题需要包括一个可靠地再现问题的好例子。对于网络代码，这意味着您需要同时包括客户端和服务器。此外，您需要提供比“不工作”更具体的问题陈述。调试程序什么也不显示。我的服务器端：这不是问题的答案。无论如何，它都无法解释OP的代码为什么不起作用。还要注意，您声称OP应该使用套接字是愚蠢的。他们正在使用

TcpClient

，它只是套接字的包装器，是执行网络操作的完美方式。最后，仅仅是代码转储的帖子，没有任何有用的解释，是没有用的。
