我想知道 Task.delay Task.Wait 和 Thread.sleep 之间的区别
当我们使用thread.sleep时。从睡眠中唤醒后,将创建一个新堆栈。请让我告诉我它们之间真正的区别是什么。
基本上Wait()和Sleep()都是线程阻塞操作,换句话说,它们强制线程闲置而不是在其他地方工作。Delay另一方面,在内部使用一个计时器来释放正在使用的线程,直到延迟完成。
关于这三个函数还有很多内容可以说,因此这里有一个小样本集供进一步阅读。

public class WaitSleepDelay
{
/// <summary>
/// The thread is released and is alerted when the delay finishes
/// </summary>
/// <returns></returns>
public async Task Delay()
{
//This Code Executes
await Task.Delay(1000);
//Now this code runs after 1000ms
}
/// <summary>
/// This blocks the currently executing thread for the duration of the delay.
/// This means that the thread is held hostage doing nothing
/// instead of being released to do more work.
/// </summary>
public void Sleep()
{
//This Code Executes
Thread.Sleep(1000);
//Now this code runs after 1000ms
}
/// <summary>
/// This blocks the currently executing thread for the duration of the delay
/// and will deadlock in single threaded sync context e.g. WPF, WinForms etc.
/// </summary>
public void Wait()
{
//This Code Executes
Task.Delay(1000).Wait();
//This code may never execute during a deadlock
}
}
