没有睡觉等待？

Question

我正在尝试做的是启动一个函数,然后将bool更改为false,等待一秒钟再次将其变为true.但是我想在没有等待功能的情况下这样做,我该怎么做？

我只能使用Visual C#2010 Express.

这是有问题的代码.我正在尝试接收用户输入(例如右箭头)并相应地移动,但在角色移动时不允许进一步输入.

        x = Test.Location.X;
        y = Test.Location.Y;
        if (direction == "right") 
        {
            for (int i = 0; i < 32; i++)
            {
                x++;
                Test.Location = new Point(x, y);
                Thread.Sleep(31);
            }
        }
    }

    private void Form1_KeyDown(object sender, KeyEventArgs e)
    {
        int xmax = Screen.PrimaryScreen.Bounds.Width - 32;
        int ymax = Screen.PrimaryScreen.Bounds.Height - 32;
        if (e.KeyCode == Keys.Right && x < xmax) direction = "right";
        else if (e.KeyCode == Keys.Left && x > 0) direction = "left";
        else if (e.KeyCode == Keys.Up && y > 0) direction = "up";
        else if (e.KeyCode == Keys.Down && y < ymax) direction = "down";

        if (moveAllowed)
        {
            moveAllowed = false;
            Movement();
        }
        moveAllowed = true;  
    }

使用Task.Delay:

Task.Delay(1000).ContinueWith((t) => Console.WriteLine("I'm done"));

要么

await Task.Delay(1000);
Console.WriteLine("I'm done");

对于旧框架,您可以使用以下内容:

var timer = new System.Timers.Timer(1000);
timer.Elapsed += delegate { Console.WriteLine("I'm done"); };
timer.AutoReset = false;
timer.Start();

根据问题中的描述示例:

class SimpleClass
{
    public bool Flag { get; set; }

    public void function()
    {
        Flag = false;
        var timer = new System.Timers.Timer(1000);
        timer.Elapsed += (src, args) => { Flag = true; Console.WriteLine("I'm done"); };
        timer.AutoReset = false;
        timer.Start();
    }
}
