Question

I’ve written this very simple function to replace a file extension using LINQ in C#.NET 3.5 however I have a feeling that there’s a more elegant way to do this. (I’m not committed to using LINQ here – just looking for a more elegant approach.) Ideas?

    private string ReplaceFileExtension(string fileName, string newExtension)     {         string[] dotSplit = fileName.Split('.');         return String.Join('.', dotSplit.Take(dotSplit.Length - 1).ToArray()) + '.' + newExtension;     } 

(I’m aware of the fact that this won’t work if the original file name doesn’t have a dot.)

It’s very easy… just use System.IO.Path.ChangeExtension
