How to take an image of what is under control?

Question

Windows Forms

I have a control on which there are other elements. The control does not fit into the parent control.
How can I get a screenshot of such content in an image file?

Answer 1

Bitmap bmp = new Bitmap(button1.Width, button1.Height);
button1.DrawToBitmap(bmp, button1.ClientRectangle);

instead of "button1" - the name of your control
