Remove file extension from a file name string

Question

If I have a string saying \"abc.txt\", is there a quick way to get a substring that is just \"abc\"?

I can\'t do an fileName.IndexOf(

Answer 1

There's a method in the framework for this purpose, which will keep the full path except for the extension.

System.IO.Path.ChangeExtension(path, null);

If only file name is needed, use

System.IO.Path.GetFileNameWithoutExtension(path);
