C#延时函数使用
在线程中如果需要延时,尽量不要使用Sleep()函数,这样会导致时间片切到别的线程中。
使用如下函数:
//Delay function
public static void Delay(int milliSecond)
{
int start = Environment.TickCount;
while (Math.Abs(Environment.TickCount - start) < milliSecond)
{
Application.DoEvents();
}
}
或者:
//Delay us Create a waitable timer
[DllImport("kernel32.dll")]
public static extern int CreateWaitableTimer(int lpTimerAttributes,
bool bManualReset, int lpTimerName);
public static void UsDelay(int us)
{
long duetime = -10 * us;
int hWaitTimer = CreateWaitableTimer(NULL, true, NULL);
SetWaitableTimer(hWaitTimer, ref duetime, 0, NULL, NULL, false);
while (MsgWaitForMultipleObjects(1, ref hWaitTimer, false, Timeout.Infinite,
QS_TIMER)) ;
CloseHandle(hWaitTimer);
}
C#3个延时函数
public static void Delays(int DelayTime = 100)
{
int time = Environment.TickCount;
while (true)
{
if (Environment.TickCount - time >= DelayTime)
{
break;
}
Application.DoEvents();
Thread.Sleep(10);
}
}
public static void Delay1(int milliSecond)
{
int start = Environment.TickCount;
while (Math.Abs(Environment.TickCount - start) < milliSecond)
{
Application.DoEvents();
}
}
//延时程序 秒
public static bool Delay2(int delayTime)
{
DateTime now = DateTime.Now;
int s;
do
{
TimeSpan spand = DateTime.Now - now;
s = spand.Seconds;
Application.DoEvents();
}
while (s < delayTime);
return true;
}
以上为个人经验,希望能给大家一个参考,也希望大家多多支持编程网。
