這篇文章主要介紹了C#實現(xiàn)簡單聊天程序的方法,實例分析了C#聊天程序的原理與客戶端、服務(wù)器端的實現(xiàn)技巧,需要的朋友可以參考下

本文實例講述了C#簡單聊天程序?qū)崿F(xiàn)方法。分享給大家供大家參考。具體如下：

假如有服務(wù)器端程序,ChatServer和客戶端程序ChatClient.實現(xiàn)客戶端向服務(wù)器端發(fā)送信息的簡單功能.

運行步驟,

1.先是服務(wù)器端start listen,
2.然后客戶端connect.
3.客戶端發(fā)送消息
 
只要服務(wù)器端start listen了,然后客戶端也connect了.這樣建立起連接后.接受發(fā)送信息就方便了,只要用writer,reader去操作NetworkStream
 
服務(wù)器ChatServer
創(chuàng)建一個WinForm頁面
引用命名空間:

using System.Net.Sockets;
using System.Net;
using System.IO;
using System.Threading;
public class ChatServer
{
private int port = 54321; //端口號
private IPAddress ip = IPAddress.Parse("10.20.30.40"); //ip地址
private TcpListener tcpListener= null;
private TcpClient tcpClient = null;
private NetworkStream networkStream = null;
private BinaryReader reader;
//private BinaryWriter writer;
private string getInfo = string.empty;
//開始監(jiān)聽
private void btnStartListen_Click(object sender, EventArgs e)
{
   tcpListener= new TcpListener( ip , port);
   tcpListener.Start(); //開始監(jiān)聽
   Thread acceptClientMsgThread= new Thread(AcceptClientMsg);
   //運行一個線程去處理客戶端發(fā)來的信息
   acceptClientMsgThread.Start();
}
//處理客戶端發(fā)來的信息
private void AcceptClientMsg()
 {
  tcpClient = tcpListener.AcceptTcpClient();
  if( tcpClient != null)
  {
    networkStream = tcpClient.GetStream();
    reader = new BinaryReader( networkStream);
    while (true){
     getInfo += reader.ReadString();  //讀取客戶端發(fā)來的信息
    }
  }
}
//假如還要顯示信息的話,可以整個顯示按鈕(當(dāng)然最好的辦法是用些線程)
//然后點擊button后讓信息顯示出來txtShowClientMsg.Text = getInfo;
//如果服務(wù)器端想再給客戶端發(fā)信息,就可以整個發(fā)送按鈕.然后添加如下代碼
//string sendMsg = txtSendMsge.Text;
//writer = new BinaryWriter( networkStream);
//writer.write( sendMsg);
}

客戶端ChatClient

using System.Net.Sockets;
using System.Net;
using System.IO;
using System.Threading;
public class ChatClient
{
 private int port = 54321;
private IPAddress ip = IPAddress.Parse("10.20.30.40");
private TcpClient tcpClient = null;
private NetworkStream networkStream = null;
//private BinaryReader reader;
private BinaryWriter writer;
//連接server
private void btnStartConnect_Click(object sender, EventArgs e)
{
 tcpClient = new TcpClient();
 tcpClient.Connect( ip, port);
 networkStream = tcpClient.GetStream();
}
//發(fā)送信息
private void btnStartConnect_Click(object sender, EventArgs e)
{
 string sendMsg = txtSendMsg.Text;
 writer = new BinaryWriter( networkStream);
 writer.Write( sendMsg); //發(fā)送信息
}
//如果還要接受server的消息的話.
//reader = new BinaryReader( networkStream);
//string getInfo = reader.ReadString();
}

希望本文所述對大家的C#程序設(shè)計有所幫助。
