How do I capture the current screen as an image?

问题:

I want to add the ability for the users to capture the current screen in my app and email it. I have a very non-technical user base so I need this to be as simple as possible. I plan to let them click a menu item called Help Me! which will then capture the current Application Screen, hopefully as a jpg or png, and then open Outlook and add the image as an attachment.

I was reading through this post ScreenCapture on Code Project but it is a little old and isn't exactly what I was looking for so I thought I would check if there is a better way of doing this.

How do I get started on this? Is there a library or are the built in capabilities enough?

Thanks!

That post you linked is the right approach, they just made it very complex. You would want to use Graphics.CopyFromScreen.

Rectangle bounds = this.Bounds;

using(Bitmap ss = new Bitmap(bounds.Width, bounds.Height))
using(Graphics g = Graphics.FromImage(ss))
{
  g.CopyFromScreen(this.Location, Point.Empty, bounds.Size);
  ss.Save("test.jpg", ImageFormat.Jpeg);
}

Check the Graphics.CopyFromScreen method.
