private void button2_Click(object sender, EventArgs e)
{
waitCallback = new WaitCallback(MyThreadWork);
ThreadPool.QueueUserWorkItem(waitCallback, "第一个线程");
ThreadPool.QueueUserWorkItem(waitCallback, "第二个线程");
ThreadPool.QueueUserWorkItem(waitCallback, "第三个线程");
ThreadPool.QueueUserWorkItem(waitCallback, "第四个线程");
}
public void MyThreadWork(object state)
{
int i=0;
while (i<20)
{
i++;
SetText(string.Format("线程现在开始启动…… {0}", (string)state));
Thread.Sleep((new Random(5)).Next()*1000);
SetText(string.Format("运行结束…… {0}", (string)state));
}
}
public delegate void mydeleg(string str);
public void SetText(string str)
{
if (textBox1.InvokeRequired)
{
textBox1.Invoke(new mydeleg(SetText),str);
}
else
textBox1.Text = str;
}
如上，想在点击Button2之后主线程仍能继续，而线程池里线程也能自己跑。 另外希望主线程里可以控制线程池里所有线程Abort掉。
