指定时间终止线程？

private IPEndPoint sendPoint; //本地网络端点
private int port = 1171; //本地的端口号
private int desPort = 20048; //远端机顶盒的端口号
private Thread startServer;
private Thread setThreadFlag; //用于设置startServer线程的
private bool threadFlag;
private StringBuilder sb = new StringBuilder();

#region Web 窗体设计器生成的代码

{
//

InitializeComponent();
base.OnInit(e);
}
