To create a screenshot in c# we need to use drawing api of the .net framework
First you have import System.Drawing.Imaging name space with following code...
using System.Drawing.Imaging;
here is the code in C# for screenshot.
int screenWidth = Screen.GetBounds(new Point(0, 0)).Width;
int screenHeight = Screen.GetBounds(new Point(0, 0)).Height;
Bitmap bmpScreenShot = new Bitmap(screenWidth, screenHeight);
Graphics gfx = Graphics.FromImage((Image)bmpScreenShot);
gfx.CopyFromScreen(0, 0, 0, 0, new Size(screenWidth, screenHeight));
bmpScreenShot.Save("test.jpg", ImageFormat.Jpeg);

Your code will leak handles. You should really dispose the Graphics-object and the Bitmap at the end. Here's an alternative version:
Rectangle bounds = Screen.GetBounds(Point.Empty);
using(Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
{
using(Graphics g = Graphics.FromImage(bitmap))
{
g.CopyFromScreen(Point.Empty, Point.Empty, bounds.Size);
}
bitmap.Save("test.jpg", ImageFormat.Jpeg);
}
Leak handles? This is managed code, why would you think that?
The "Leak Handles" version is funny. Like the guy is a paranoid c++ freak from 10 years back. If that code was required to avoid leaks, I would slit my wrists right now and get the pain of programming with memory management of my chest right now.
