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.

property is used to position an image within a PictureBox. It can be Normal,
StretchImage, AutoSize, CenterImage, and Zoom. The following code snippet sets
