Taking a Snap Shot of screen in .NET

Introduction: Here I need to take a snap shot my screen with my web application on just a button click.

Requirement: For this I need only a Button, by clicking on that the snap shot of screen is taken and saved                            automatically.

Namespaces Required:

using System.Drawing;

using System.Drawing.Imaging;

Click event of Button:

        Bitmap bitmap = new Bitmap(1000, 1000); //declaring size of snap
        Graphics graphics = Graphics.FromImage(bitmap as System.Drawing.Image);
        graphics.CopyFromScreen(0, 0, 0, 0, bitmap.Size);
        bitmap.Save(@"c:\Snapshot\screenshot1.bmp", ImageFormat.Bmp); //Path to save image

Result:  
        This code will save the snap shot of screen to the location defined in the code.
