论坛: 编程破解标题: C#的Socket简单问题求助

程序中我用了命名控件using System.Net.Sockets ;
在class中定义private Socket stSend;的时候调试说错误～～
错误信息是"Socket"表示“命名空间”，此处应为“类”
我就很奇怪～～
我的代码如下
using System ;
using System.Drawing ;
using System.Collections ;
using System.ComponentModel ;
using System.Windows.Forms ;
using System.Data ;
using System.Net.Sockets ;
//使用到TcpListen类
using System.Net ;

namespace Socket
{
/// <summary>
/// Form1 的摘要说明。
/// </summary>
public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.TextBox textBox1;
private System.Windows.Forms.TextBox textBox2;
private System.Windows.Forms.Label label1;
private System.Windows.Forms.Label label2;
private System.Windows.Forms.Label label3;
private System.Windows.Forms.ListBox listBox1;
private System.Windows.Forms.StatusBar statusBar1;
private System.Windows.Forms.Button button1;
private System.Windows.Forms.Button button2;
/// <summary>
/// 必需的设计器变量。
/// </summary>
private System.ComponentModel.Container components = null;
int port = 8000 ;
//定义侦听端口号
private TcpClient tcpc ;
//对服务器端创建TCP连接
private Socket stSend ;
//创建发送数据套接字
private bool tcpConnect = false ;
//定义标识符，用以表示TCP连接是否建立

public Form1()
{
