Introduction
Here we will implement a Windows Forms application to capture a screen using C#.
It is a very short demo especially for beginners.
Procedure
Step 1: Create a new “Windows Forms application” in Visual Studio and name it as you choose (I here named it ScreenCaptureDemo).
Now a new form is generated.
Step 2: Now go to the toolbox and add a Button Control to the project also resize the window size.
The form will look like this:
![]()
Step 3: Add the following using directives:
using System.Drawing.Imaging;
using System.Drawing;
using System;
Step 4: Now navigate to the code file Form1.cs and the following code in the Button Event Handler that we added to our project.
private void buttonCapture_Click(object sender, EventArgs e)
{
//Creating a Method name CaptureMyScreen
CaptureMyScreen();
}
private void CaptureMyScreen()
{
}
Step 5: Now add the following code into the method that we created (CaptureMyScreen()):
private void CaptureMyScreen()
{
try
{
//Creating a new Bitmap object
Bitmap captureBitmap = new Bitmap(1024, 768, PixelFormat.Format32bppArgb);
//Bitmap captureBitmap = new Bitmap(int width, int height, PixelFormat);
//Creating a Rectangle object which will
//capture our Current Screen
Rectangle captureRectangle = Screen.AllScreens[0].Bounds;
//Creating a New Graphics Object
Graphics captureGraphics = Graphics.FromImage(captureBitmap);
//Copying Image from The Screen
captureGraphics.CopyFromScreen(captureRectangle.Left,captureRectangle.Top,0,0,captureRectangle.Size);
//Saving the Image File (I am here Saving it in My E drive).
captureBitmap.Save(@"E:\Capture.jpg",ImageFormat.Jpeg);
//Displaying the Successfull Result
MessageBox.Show("Screen Captured");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
Step 6: Now compile it and run it.
You will get your captured screen.
That's all for this article. I am embedding the source file so that you can go through it.
Thank You.
