Return filename without extension from full path in C# [duplicate]

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?
