Get file name from URI string in C

Questions

I have this method for grabbing the file name from a string URI. What can I do to make it more robust?

private string GetFileName(string hrefLink)
{
    string[] parts = hrefLink.Split( / );
    string fileName = "";

    if (parts.Length > 0)
        fileName = parts[parts.Length - 1];
    else
        fileName = hrefLink;

    return fileName;
}

This is much safer, as it provides you a means to check the validity of the URI as well.

Edit in response to comment:

To get just the full filename, I d use:

Uri uri = new Uri(hreflink);
if (uri.IsFile) {
    string filename = System.IO.Path.GetFileName(uri.LocalPath);
}

This does all of the error checking for you, and is platform-neutral. All of the special cases get handled for you quickly and easily.
