防止线程同时执行两次

 

private void timerSW_Tick(object sender, EventArgs e)
        {
            if (this.tReceive.ThreadState != ThreadState.Running)//判断线是否正在执行
            {
                this.tReceive = new Thread(new ThreadStart(Function));
                this.tReceive.Start();
            }
        }

pubilc void Function()

{

//.....

this.tReceive.Abort();

}
