I am building an asp website. I want to show image on the page, but while I know the image name, I don't know the extension.

So, I want to open the images directory and get the image by its name whatever its extension.

You can use the Directory object to get a list of file in a directory

string imageFilename = System.IO.Directory.GetFiles( imageDirectory, name + ".*" ).First();

That's not really how files work -- you need to know the whole name. For example, what happens if there's multiple images with the same base name and different extensions? Compare foo.png and foo.jpg, for example.

One suggestion is to try doing a wildcard search on all files with some base name in that directory (that's what bstoney's solution does; see here). If you find exactly one match, you're done. If you get multiple matches, you'll need to make rules about which one wins.
