C#网络编程服务器端程序实现源码是怎么样的呢?让我们来看看其中重要的一部分:
由于在此次程序中我们采用的结构是异步阻塞方式,所以在实际的程序中,为了不影响服务器端程序的运行速度,我们在程序中设计了一个线程,使得对网络请求侦听,接受和发送数据都在线程中处理,请在下面的代码中注意这一点,下面是C#网络编程服务器端程序的完整代码:
//server.cs
using System ;
using System.Drawing ;
using System.Collections ;
using System.ComponentModel ;
using System.Windows.Forms ;
using System.Data ;
using System.Net.Sockets ;
using System.IO ;

using System.Net ;
//C#网络编程服务器端程序
//导入程序中使用到的名字空间
public class Form1 : Form

private ListBox ListBox1 ;

}
//C#网络编程服务器端程序
//清除程序中使用的各种资源
protected override void Dispose ( bool disposing )
{

{
if ( components != null )
{
components.Dispose ( ) ;
}
}
base.Dispose ( disposing ) ;
}

label1.Text = "往客户端反馈信息:" ;
//C#网络编程服务器端程序
//同样的方式设置其他控件,这里略去
this.Controls.Add ( button1 ) ;

}
private void Listen ( )
{
//C#网络编程服务器端程序
//创建一个tcpListener对象,此对象主要是对给定端口进行侦听
tcpListener = new TcpListener ( 1234 ) ;
//开始侦听
tcpListener.Start ( ) ;
//返回可以用以处理连接的Socket实例
socketForClient = tcpListener.AcceptSocket ( ) ;
try
{
//如果返回值是"true",则产生的套节字已经接受来自远方的连接请求
if ( socketForClient.Connected )
{
ListBox1.Items.Add ( "已经和客户端成功连接!" ) ;
while ( true )
{
//创建networkStream对象通过网络套节字来接受和发送数据
networkStream = new NetworkStream ( socketForClient ) ;
//从当前数据流中读取一行字符,返回值是字符串
streamReader = new StreamReader ( networkStream ) ;
string msg = streamReader.ReadLine ( ) ;
ListBox1.Items.Add ( "收到客户端信息:" + msg ) ;
streamWriter = new StreamWriter ( networkStream ) ;
if ( textBox1.Text != "" )
{
ListBox1.Items.Add ( "往客户端反馈信息:" +
textBox1.Text ) ;
//往当前的数据流中写入一行字符串
streamWriter.WriteLine ( textBox1.Text ) ;
//刷新当前数据流中的数据
//C#网络编程服务器端程序
streamWriter.Flush ( ) ;
}
}
}
}
catch ( Exception ey )
{
MessageBox.Show ( ey.ToString ( ) ) ;
}
}
static void Main ( )
{
Application.Run ( new Form1 ( ) ) ;
