Capture Screen (The Express Way in 5 Lines)

[Atran]

Hello Everyone.
In this article: You will know to capture the screen in 2 ways:
1)- Capture full screen.
2)- Capture region.

Let's Begin:
First make a new Windows Application project.
And make sure your program uses these namespaces:

using System;
using System.Drawing;
using System.Drawing.Imaging;
using System.Windows.Forms;
 

Now, we will begin writing the code:
1)- Create a new bitmap object.

//Bitmap screenBitmap = new Bitmap(int width, int height, PixelFormat);
Bitmap screenBitmap = new Bitmap(1024, 768, PixelFormat.Format32bppArgb);
 

2)- Create a new rectangle object.

//screenRegion will grab the size of your current screen.
Rectangle screenRegion = Screen.AllScreens[0].Bounds;
 

3)- Create a new graphics object.

Graphics screenGraphics = Graphics.FromImage(screenBitmap);
 

4)- Copy the image from the screen.

//screenGraphics will copy the image from the screen.
screenGraphics.CopyFromScreen(screenRegion.Left, screenRegion.Top, 0, 0, screenRegion.Size);
 

5)- Save the image:

screenBitmap.Save(@"C:\Screen.jpg", ImageFormat.Jpeg);
 

Here is the code:

Bitmap screenBitmap = new Bitmap(1024, 768, PixelFormat.Format32bppArgb);
Rectangle screenRegion = Screen.AllScreens[0].Bounds;
 
// It will copy the current screep image to the bitmap image.
Graphics screenGraphics = Graphics.FromImage(screenBitmap);
screenGraphics.CopyFromScreen(screenRegion.Left, screenRegion.Top, 0, 0, screenRegion.Size); 
 
screenBitmap.Save(@"c:\test.jpg", ImageFormat.Jpeg);
 

You can also capture a part of the screen (region):

/* The Code was:
   screenGraphics.CopyFromScreen(screenRegion.Left, screenRegion.Top, 0, 0, screenRegion.Size); 
*/
 
//See the difference.
 
//screenGraphics.CopyFromScreen(intSourceX, intSourceY......);
screenGraphics.CopyFromScreen(200, 300, 0, 0, screenRegion.Size);
 

Hope this help you.

Great tip
this is something that I can use daily with a few modifications.
I do not use C# though so I thought that you would not mind if I posted the VB code

Imports System
Imports System.drawing
Imports System.Drawing.Imaging
Imports System.Windows.Forms
        Dim screenBitmap As New Bitmap(1024, 768, PixelFormat.Format32bppArgb)
        Dim screenRegion As Rectangle = Screen.AllScreens(0).Bounds
 
        ' It will copy the current screep image to the bitmap image.
        Dim screenGraphics As Graphics = Graphics.FromImage(screenBitmap)
        screenGraphics.CopyFromScreen(screenRegion.Left, screenRegion.Top, 0, 0, screenRegion.Size)
 
        screenBitmap.Save("c:\test.jpg", ImageFormat.Jpeg)
