How to select a region in a Windows Forms PictureBox?

I want to get a part of picture in a PictureBox by allowing the user to select a rectangular region (similar to how it can be done in Photoshop with selection tool).

How I can do this?

From stackoverflow

• You would have to draw a rectangle or lines based on where they clicked and dragged. Your starting point would be the mouse x, y and then you would get the last point from mouse release x, y.

  sashaeve : Thanks, @Icono123. This is exactly what I need.

• Catch the mouse events on the Picture Box to define your selection rectangle and use Graphics.DrawRectangle to draw your selection rectangle in the Paint Event of the Picture Box.
