How can i draw to screen?

Question

我的意思是使用paint事件，而不是在pictureBox1.Image上绘制，而不是在pictureBox1中当前显示的图像上绘制/绘制图像，只是为了在屏幕上自行绘制？

Answer 1

It isn't possible to draw out of a form's (or control's) client area. You could make a fullscreen form (Maximized, no borders) That can have a transparent color as it's bgcolor, and just paint to it using the paint event.
