Return filename without extension from full path in C#

Question

I'm looking for a way to return fileName from full path but without extension.

    private static string ReturnFileNameWithoutExtension(string varFullPathToFile) {
        string fileName = new FileInfo(varFullPathToFile).Name;
        string extension = new FileInfo(varFullPathToFile).Extension;
        return fileName.Replace(extension, "");   
    }

Is there more bullet proof solution then replacing extension with empty string?

what if you haven't got the full path? – Boomerang Nov 12 '14 at 16:29
It's just the same: "somefile.txt" will return "somefile" – Gonzalo Nov 12 '14 at 19:56

One More solution

string fileName = new FileInfo(varFullPathToFile).Name;
fileName=fileName.Substring(0, fileName.LastIndexOf("."));
