As sirbounty has suggested the String.Replace method is the directy approach.

But you might also wanna take a look at the Path.ChangeExtension method.  It is designed to do precisely what you want.  Take a look at other members of the Path class, you might find them useful... they allow you easily to break up the full path into it's consitutient parts (drive letter, path, file name, extention, etc)
