三.本文介绍程序的设计、调试、运行的软件环境
(1).微软公司视窗2000服务器版 < br>
(2).Visual Studio .Ne t正式版,.Net FrameWork SDK版本号3705
四.利用Socket来传送数据:
Visual C#在使用Socket传送数据时要注意 下列问题的解决方法:
1.创建Socket实 例,使用此实例创建和远程终结点的连接,并判断连接是否成功建立 。
2.发送数据到Socket,实现数据传送 。
这些问题解决方法都可以在下面介绍代码中找 到相对应的部分。由于下面的代码都有详细的注解,
这里就不详细介绍。下面是利用Socket传送数据的具体实 现步骤:
1.启动Visual Studio .Net,并新建一个Visual C#项目,
项目名称为【利用Socket来发送数据】。
2.把Visual Studio .Net的当前窗口切换 到【Form1.cs(设计)】窗口,
并从【 工具箱】中的【Windows窗体组件】选项卡中往Form1窗 体中拖入下列组件,并执行相应操作:
二个Te xtBox组件,一个用以输入远程主机的IP地址,一个用以输入 往远程主机传送的数据。
一个StausBar 组件,用以显示程序的运行状况。
一个List Box组件,用以显示程序已传送的数据信息。
三个Label组件。
二个Button组件, 名称分别为button1、button2,并在这二个组件被拖 入窗体后,分别双击它们,则系统会在Form1.cs文件中自动 产生这二个组件的Click事件对应的处理代码。
3.【解决方案资源管理器】窗口中,双击Form1.cs文 件,进入Form1.cs文件的编辑界面。
4 .以下面代码替代系统产生的InitializeCompone nt过程:
private void Initiali zeComponent ( )
{
this. label1 = new System.Windows.Fo rms.Label ( ) ;
this.textB ox1 = new System.Windows.Forms .TextBox ( ) ;
this.button 1 = new System.Windows.Forms.B utton ( ) ;
this.label2 = new System.Windows.Forms.Label ( ) ;
this.textBox2 = new System.Windows.Forms.TextBox ( ) ;

this.textBox1.Size = new System.Drawing.Size ( 166 , 2 1 ) ;
this.textBox1.TabInd ex = 1 ;
this.textBox1.Tex t = "" ;
this.button1.Flat Style = System.Windows.Forms.F latStyle.Flat ;
this.butto n1.Location = new System.Drawi ng.Point ( 280 , 14 ) ;
th is.button1.Name = "button1" ;
< br> this.button1.Size = new Sy stem.Drawing.Size ( 62 , 28 ) ;
this.button1.TabIndex = 2 ;
this.button1.Text = "连 接" ;
this.button1.Click += new System.EventHandler ( thi s.button1_Click ) ;
this.l abel2.Location = new System.Dr awing.Point ( 16 , 64 ) ;
this.label2.Name = "label2" ;
< br> this.label2.TabIndex = 3 ;
this.label2.Text = "发送信息: " ;
this.textBox2.BorderSt yle = System.Windows.
Forms.BorderStyle.FixedSin gle ;
this.textBox2.Locati on = new System.Drawing.Point ( 94 , 58 ) ;
this.textBox 2.Name = "textBox2" ;
this .textBox2.Size = new System.Dr awing.Size ( 166 , 21 ) ;
this.textBox2.TabIndex = 4 ;
this.textBox2.Text = "" ;
this.listBox1.ItemHeight = 12 ;
this.listBox1.Locatio n = new System.Drawing.Point ( 20 , 118 ) ;
this.listBox 1.Name = "listBox1" ;
this .listBox1.Size = new System.Dr awing.Size ( 336 , 160 ) ;
this.listBox1.TabIndex = 6 ;
< br> this.statusBar1.Location = new System.Drawing.Point ( 0 , 295 ) ;
this.statusBar1. Name = "statusBar1" ;
this .statusBar1.Size = new System. Drawing.Size ( 370 , 22 ) ;
this.statusBar1.TabIndex = 7 ;
this.statusBar1.Text = "无连接" ;
this.label3.Locati on = new System.Drawing.Point ( 14 , 94 ) ;
this.label3. Name = "label3" ;
this.lab el3.Size = new System.Drawing. Size ( 128 , 23 ) ;
this.l abel3.TabIndex = 8 ;
this. label3.Text = "已经发送的信息:" ;
this.button2.FlatStyle = Syst em.Windows.Forms.FlatStyle.Fla t ;
this.button2.Location = new System.Drawing.Point ( 2 80 , 54 ) ;
this.button2.N ame = "button2" ;
this.but ton2.Size = new System.Drawing .Size ( 62 , 28 ) ;
this.b utton2.TabIndex = 9 ;
this .button2.Text = "发送" ;
thi s.button2.Click += new System. EventHandler
( thi s.button2_Click ) ;
this.A utoScaleBaseSize = new System. Drawing.Size ( 6 , 14 ) ;
this.ClientSize = new System.D rawing.Size ( 370 , 317 ) ;
this.Controls.AddRange ( new System.Windows.Forms.Control[ ] {
this.button2 ,
this.statusBar1 ,
th is.listBox1 ,
this.text Box2 ,
this.label2 ,
this.button1 ,
thi s.textBox1 ,
this.label 1 ,
this.label3} ) ;
this.FormBorderStyle = Syste m.
Windows.Forms.F ormBorderStyle.FixedSingle ;
this.MaximizeBox = false ;
< br> this.Name = "Form1" ;
this.Text = "利用Socket来发送数据" ;
< br> this.ResumeLayout ( false ) ;
}
至此【利 用Sokcet来传送数据】项目设计后的界面就完成了,具体如图 01所示:

5.在Form1. cs文件的开头的导入命名空间的代码区,添加下列代码,
下列代码是导入下面程序中使用到的类所在的命名空间: < br>
u sing System ;
using System. Drawing ;
using System.Coll ections ;
using System.Comp onentModel ;
using System.W indows.Forms ;
using System .Data ;
using System.Net.So ckets ;
//使用到TcpListen类
using System.Net ;
