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

You can use

string extension = System.IO.Path.GetExtension(filename);

And then remove the extension manually:

string result = filename.Substring(0, filename.Length - extension.Length);
