C#中的一些延时函数

System.Threading.Thread.Sleep(1000); //毫秒

public static void Delay(int milliSecond)
{
    int start = Environment.TickCount;
    while (Math.Abs(Environment.TickCount - start) < milliSecond)//毫秒
    {
        Application.DoEvents();//可执行某无聊的操作
    }
}

public bool Dalay(int ms)
{
    DateTime now = DateTime.Now;
    int s;
    do
    {
        TimeSpan spand = DateTime.Now - now;
        s = spand.Minutes * 60 * 1000 + spand.Seconds * 1000 + spand.Milliseconds;
        Application.DoEvents();
    }
    while (s < ms);
    return true;
