C# picturebox

You can set the Image property to the Image you want to display, either at design time or at run time. You can programmatically change the image displayed in a picture box, which is particularly useful when you use a single form to display different pieces of information.

pictureBox1.Image = Image.FromFile("c:\\testImage.jpg");

The SizeMode property, which is set to values in the PictureBoxSizeMode enumeration, controls the clipping and positioning of the image in the display area.

pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;

There are five different PictureBoxSizeMode is available to PictureBox control.

  1. AutoSize - Sizes the picture box to the image.
  2. CenterImage - Centers the image in the picture box.
  3. Normal - Places the upper-left corner of the image at upper left in the picture box
  4. StretchImage - Allows you to stretch the image in code

The PictureBox is not a selectable control, which means that it cannot receive input focus. The following C# program shows how to load a picture from a file and display it in streach mode.
