For filenames, look into System.IO.Path static members. You'll find plenty of methods there.

If you want to stick with string manipulation, something like this would be nice:

string wholeName = @"D:\MyDocuments\Pictures\Pic1.jpg";
int dotPosition = wholeName.LastIndexOf('.'); // find last dot
string ext = wholeName.Substring(dotPosition); // get out the extenstion

Simple use

string path = "D://MyDocuments/Pictures/Pic1.jpg";
            string extension = System.IO.Path.GetExtension(path);

var extension = Path.GetExtension(Server.MapPath(@"D://MyDocuments/Pictures/Pic1.jpg"));

Its can be done using substring but its better if you do it with Path.GetExtension

 string fileName = @"C:\mydir.old\myfile.ext";
 string path = @"C:\mydir.old\";
 string extension;

 extension = Path.GetExtension(fileName);

you can use the Path class to fetch the file information. 

 Path.GetExtension("youpath")

Have a look at using Path.GetExtension Method

The extension of the specified path (including the period "."), or null, or String.Empty. If path is null, GetExtension returns null. If path does not have extension information, GetExtension returns String.Empty.
