C#網絡編程服務器端程序實現源碼淺析
作者:佚名
C#網絡編程服務器端程序實現源碼向你介紹了用結構是異步阻塞方式下的程序實現,希望對你了解和學習C#網絡編程服務器端程序有所幫助。
C#網絡編程服務器端程序實現源碼是怎么樣的呢?讓我們來看看其中重要的一部分:
由于在此次程序中我們采用的結構是異步阻塞方式,所以在實際的程序中,為了不影響服務器端程序的運行速度,我們在程序中設計了一個線程,使得對網絡請求偵聽,接受和發送數據都在線程中處理,請在下面的代碼中注意這一點,下面是C#網絡編程服務器端程序的完整代碼:
- //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.Threading ;
- using System.Net ;
- //C#網絡編程服務器端程序
- //導入程序中使用到的名字空間
- public class Form1 : Form
- {
- private ListBox ListBox1 ;
- private Button button2 ;
- private Label label1 ;
- private TextBox textBox1 ;
- private Button button1 ;
- private Socket socketForClient ;
- private NetworkStream networkStream ;
- private TcpListener tcpListener ;
- private StreamWriter streamWriter ;
- private StreamReader streamReader ;
- private Thread _thread1 ;
- private System.ComponentModel.Container components = null ;
- public Form1 ( )
- {
- InitializeComponent ( ) ;
- }
- //C#網絡編程服務器端程序
- //清除程序中使用的各種資源
- protected override void Dispose ( bool disposing )
- {
- if ( disposing )
- {
- if ( components != null )
- {
- components.Dispose ( ) ;
- }
- }
- base.Dispose ( disposing ) ;
- }

- label1.Name = "label1" ;
- label1.Size = new Size ( 120 , 23 ) ;
- label1.TabIndex = 3 ;
- label1.Text = "往客戶端反饋信息:" ;
- //C#網絡編程服務器端程序
- //同樣的方式設置其他控件,這里略去
- this.Controls.Add ( button1 ) ;
- this.Controls.Add ( textBox1 ) ;
- this.Controls.Add ( label1 ) ;
- this.Controls.Add ( button2 ) ;
- this.Controls.Add ( ListBox1 ) ;
- this.MaximizeBox = false ;

- this.Name = "Form1" ;
- this.Text = "C#的網絡編程服務器端!" ;
- this.Closed += new System.EventHandler ( this.Form1_Closed ) ;
- this.ResumeLayout ( false ) ;
- }
- private void Listen ( )
- {
- //C#網絡編程服務器端程序
- //創建一個tcpListener對象,此對象主要是對給定端口進行偵聽
- tcpListener = new TcpListener ( 1234 ) ;
- //開始偵聽
- tcpListener.Start ( ) ;
- //返回可以用以處理連接的Socket實例
- socketForClient = tcpListener.AcceptSocket ( ) ;
- try
- {
- //如果返回值是"true",則產生的套節字已經接受來自遠方的連接請求
- if ( socketForClient.Connected )
- {
- ListBox1.Items.Add ( "已經和客戶端成功連接!" ) ;
- while ( true )
- {
- //創建networkStream對象通過網絡套節字來接受和發送數據
- networkStream = new NetworkStream ( socketForClient ) ;
- //從當前數據流中讀取一行字符,返回值是字符串
- streamReader = new StreamReader ( networkStream ) ;
- string msg = streamReader.ReadLine ( ) ;
- ListBox1.Items.Add ( "收到客戶端信息:" + msg ) ;
- streamWriter = new StreamWriter ( networkStream ) ;
- if ( textBox1.Text != "" )
- {
- ListBox1.Items.Add ( "往客戶端反饋信息:" +
- textBox1.Text ) ;
- //往當前的數據流中寫入一行字符串
- streamWriter.WriteLine ( textBox1.Text ) ;
- //刷新當前數據流中的數據
- //C#網絡編程服務器端程序
- streamWriter.Flush ( ) ;
- }
- }
- }
- }
- catch ( Exception ey )
- {
- MessageBox.Show ( ey.ToString ( ) ) ;
- }
- }
- static void Main ( )
- {
- Application.Run ( new Form1 ( ) ) ;
- }
- private void button1_Click ( object sender ,
- System.EventArgs e )
- {
- ListBox1.Items .Add ( "服務已經啟動!" ) ;
- _thread1 = new Thread ( new ThreadStart ( Listen ) ) ;
- _thread1.Start ( ) ;

- private void button2_Click ( object sender ,

- {
- //C#網絡編程服務器端程序
- //關閉線程和流
- networkStream.Close ( ) ;
