c# - 将 Thread.Sleep() 替换为 System.Windows.Forms.Timer()

Question

public static class SampleMouseMove
{

    static Random random = new Random();
    static int mouseSpeed = 15;

    public static void MoveMouse(int x, int y, int rx, int ry)
    {
        Point c = new Point();
        GetCursorPos(out c);

        x += random.Next(rx);
        y += random.Next(ry);

        double randomSpeed = Math.Max((random.Next(mouseSpeed) / 2.0 + mouseSpeed) / 10.0, 0.1);

        WindMouse(c.X, c.Y, x, y, 9.0, 3.0, 10.0 / randomSpeed,
            15.0 / randomSpeed, 10.0 * randomSpeed, 10.0 * randomSpeed);
    }

    static void WindMouse(double xs, double ys, double xe, double ye,
        double gravity, double wind, double minWait, double maxWait,
        double maxStep, double targetArea)
    {

        double dist, windX = 0, windY = 0, veloX = 0, veloY = 0, randomDist, veloMag, step;
        int oldX, oldY, newX = (int)Math.Round(xs), newY = (int)Math.Round(ys);

        double waitDiff = maxWait - minWait;
        double sqrt2 = Math.Sqrt(2.0);
        double sqrt3 = Math.Sqrt(3.0);
        double sqrt5 = Math.Sqrt(5.0);

        dist = Hypot(xe - xs, ye - ys);

        while (dist > 1.0)
        {

            wind = Math.Min(wind, dist);

            if (dist >= targetArea)
            {
                int w = random.Next((int)Math.Round(wind) * 2 + 1);
                windX = windX / sqrt3 + (w - wind) / sqrt5;
                windY = windY / sqrt3 + (w - wind) / sqrt5;
            }
            else
            {
                windX = windX / sqrt2;
                windY = windY / sqrt2;
                if (maxStep < 3)
                    maxStep = random.Next(3) + 3.0;
                else
                    maxStep = maxStep / sqrt5;
            }

            veloX += windX;
            veloY += windY;
            veloX = veloX + gravity * (xe - xs) / dist;
            veloY = veloY + gravity * (ye - ys) / dist;

            if (Hypot(veloX, veloY) > maxStep)
            {
                randomDist = maxStep / 2.0 + random.Next((int)Math.Round(maxStep) / 2);
                veloMag = Hypot(veloX, veloY);
                veloX = (veloX / veloMag) * randomDist;
                veloY = (veloY / veloMag) * randomDist;
            }

            oldX = (int)Math.Round(xs);
            oldY = (int)Math.Round(ys);
            xs += veloX;
            ys += veloY;
            dist = Hypot(xe - xs, ye - ys);
            newX = (int)Math.Round(xs);
            newY = (int)Math.Round(ys);

            if (oldX != newX || oldY != newY)
                SetCursorPos(newX, newY);

            step = Hypot(xs - oldX, ys - oldY);
            int wait = (int)Math.Round(waitDiff * (step / maxStep) + minWait);

            Thread.Sleep(wait); //<---
        }

        int endX = (int)Math.Round(xe);
        int endY = (int)Math.Round(ye);
        if (endX != newX || endY != newY)
            SetCursorPos(endX, endY);
    }

    static double Hypot(double dx, double dy)
    {
        return Math.Sqrt(dx * dx + dy * dy);
    }

    [DllImport("user32.dll")]
    static extern bool SetCursorPos(int X, int Y);

    [DllImport("user32.dll")]
    public static extern bool GetCursorPos(out Point p);
}

这是我将鼠标光标移动到某个点的代码。

我想将上面的 Thread.Sleep(wait) 替换为不会使 UI 线程卡住的异步内容。我想出了如何制作一个计时器，但我不确定如何在上面的示例中使用它。

var timer = new System.Windows.Forms.Timer();
timer.Interval = wait; 
timer.Tick += (sender, args) => { /* do stuff */ };
timer.Start();

您正在让 UI 线程直接进入休眠状态。如果你想做你想做的事情，你需要把你的 while 循环放到它自己的线程中，然后让那个线程而不是 UI 线程进入休眠状态。

要么那样，要么将整个 WindMouse 方法放到它自己的后台线程中。
