使用两点捕获屏幕截图

Question

如何捕获截图，给它两个点，基本上创建一个矩形截图或什么？

我用过这个：How to create a RectangleF using two PointF?

但它似乎没有得到我想要的矩形截图，它将我带到屏幕的一角。

    private void KListener_KeyDown(object sender, RawKeyEventArgs args)
    {
        if (args.Key.ToString() == "F5")
        {
            Program.FirstPos = System.Windows.Forms.Cursor.Position;
            System.Media.SystemSounds.Asterisk.Play();
        }
        else if (args.Key.ToString() == "F6")
        {
            Program.SecondPos = System.Windows.Forms.Cursor.Position;
            System.Media.SystemSounds.Asterisk.Play();
        }
    }

    public Bitmap CaptureScreen()
    {
        RectangleF rect2 = GetRectangle(Program.FirstPos, Program.SecondPos);
        var image = new Bitmap((int)rect2.Width, (int)rect2.Height, PixelFormat.Format24bppRgb);
        var gfx = Graphics.FromImage(image);
        gfx.CopyFromScreen(Screen.PrimaryScreen.Bounds.X, Screen.PrimaryScreen.Bounds.Y, 0, 0, Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy);
        image.Save("C:\\Users\\DreTaX\\Documents\\teszt", ImageFormat.Jpeg);
        return image;
    }

Answer 1

gfx.CopyFromScreen（rect2.Left，rect2.Top，0,0，image.Size，CopyPixelOperation.SourceCopy）;
