How to get a screen capture of a .Net WinForms control programmatically?

Question

How do you programmatically obtain a picture of a .Net control?

Answer 1

There's a method on every control called DrawToBitmap. You don't need to p/invoke to do this.

Control c = new TextBox();
System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(c.Width, c.Height);
c.DrawToBitmap(bmp, c.ClientRectangle);
