推荐答案
您可以通过创建表单并将其TransparentColor属性设置为背景颜色来作弊"，然后在其上进行绘制.但是，这会禁止您绘制透明颜色，因为它不会显示.
You can "cheat" by creating a form, and setting its TransparentColor property to its background color, then draw on it. However, this prohibits you from drawing the transparent color because it won't show.
或者您实际上可以直接绘制到桌面上.
Or you could actually draw directly to the desktop.
[DllImport("User32.dll")]
public static extern IntPtr GetDC(IntPtr hwnd);
[DllImport("User32.dll")]
public static extern void ReleaseDC(IntPtr dc);
IntPtr desktopPtr = GetDC(IntPtr.Zero);
Graphics g = Graphics.FromHdc(desktopPtr);
// Do graphics manipulation here with "g" object
// Very important - free desktop graphics.
g.Dispose();
ReleaseDC(desktopPtr);
