PictureBox control is used to display images in Windows Forms. In this article, I will discuss how to use a PictureBox control to display images in Windows Forms applications.

Creating a PictureBox

PictureBox class represents a PictureBox control. The following code snippet creates a PictureBox, sets its width and height and adds control to the Form by calling Controls.Add() method.

C# Code:

PictureBox imageControl = new PictureBox();

imageControl.Width = 400;

imageControl.Height = 400;

 

Controls.Add(imageControl);

 

VB.NET Code:

 

Dim imageControl As New PictureBox()

imageControl.Width = 400

imageControl.Height = 400

Display an Image

Image property is used to set an image to be displayed in a PictureBox control. The following code snippet creates a Bitmap from an image and sets the Image property of PictureBox control. Code also sets the Dock property of PictureBox.

C# Code:                                                                                                                                  

private void DisplayImage()

{

    PictureBox imageControl = new PictureBox();

    imageControl.Width = 400;

    imageControl.Height = 400;

 

    Bitmap image = new Bitmap("C:\\Images\\Creek.jpg");

    imageControl.Dock = DockStyle.Fill;

    imageControl.Image = (Image)image;

 

    Controls.Add(imageControl);

}

 

VB.NET Code:

 

Private Sub DisplayImage()

        Dim imageControl As New PictureBox()

        imageControl.Width = 400

        imageControl.Height = 400

        Dim Image As New Bitmap("C:\\Images\\Creek.jpg")

        imageControl.Dock = DockStyle.Fill

        imageControl.Image = Image

        Controls.Add(imageControl)

    End Sub

 

The output looks like Figure 1 where an image is displayed.

C# Code:

imageControl.SizeMode = PictureBoxSizeMode.CenterImage;

 

VB.NET Code:

 

imageControl.SizeMode = PictureBoxSizeMode.CenterImage
