How to get screenshots of windows in C#

Question

Hello for the C# project I am working on I need to get screenshots of all the open windows (like the window thumbnails in the taskbar but full size). It must also get images from windows that are not on the visible screen area (half/all of the window is off the screen). Please don't reply with graphics.copyfromscreen() because it does not return parts of the window that are off the screen. Does anyone know how I can do this? If anyone has an idea please post some demo code or a place that i can find some demo code. (running Windows 7 Home with Microsoft Visual C# 2010 Express)

From my original post:  Please don't reply with graphics.copyfromscreen() because it does not return parts of the window that are off the screen.  This does not do what I need. I need a way of getting screenshots of a given window (by handle) not the screen. This answer also does not return parts of windows that are off of the screen.

void takingscreenshot(string savepath) { Rectangle bounds = this.Bounds; using (Bitmap bmpScreenCapture = new Bitmap(Screen.PrimaryScreen.Bounds.Width Screen.PrimaryScreen.Bounds.Height)) { using (Graphics g = Graphics.FromImage(bmpScreenCapture)) { g.CopyFromScreen(Screen.PrimaryScreen.Bounds.X Screen.PrimaryScreen.Bounds.Y 0 0 bmpScreenCapture.Size CopyPixelOperation.SourceCopy); } bmpScreenCapture.Save(savepath System.Drawing.Imaging.ImageFormat.Jpeg); } } ---------------------- Use this Function.
