How do I Search a string for a value?

[JohnnyBGoode]

I have a string "MyFile.doc". In the end, I would like ".doc". So, I would like to try to find the location of the ".", and then take the rest of the string. How can this be done?

Take a look at the Path class. You would do it like this:

String fileName = @"Myfile.doc";
String extension = Path.GetExtension(fileName);

It's unwise to write your own file/path handling functions, as you'd be unlikely to handle some of the stranger cases, such as UNC paths, and long Unicode paths (start with "/?///", IIRC, and are longer than MAX_PATH (255 characters))

Thanx a bunch. But one more question...which "using" statement should I use so that the "Path.GetExtension" will be recognized?

using System.IO;

Yeah, I finally found it. Thanx for your time.
