How to get file extension from OpenFileDialog?

I want just get Image(.JPG,.PNG,.Gif) File from my OpenFileDialog
How can I get file extension from OpenFileDialog?
Is it impossible?

A:

To filter only certain types of file use Filter Property
OpenFileDialog1.Filter = "Image Files (JPG,PNG,GIF)|*.JPG;*.PNG;*.GIF";

To get the file extension use the Path helper GetFileExtension
if (OpenFileDialog1.ShowDialog() == DialogResult.OK)
   string ext = Path.GetExtension(OpenFileDialog1.FileName);

Path.GetExtension(ofd.FileName);

Use this:
Path.GetExtension(dialog.FileName);
