Equivalent function to IO.Path.GetFileName for urls?

Question

In .NET 4.0, whats the equivalent function to IO.Path.GetFileName for urls?

Answer 1

You may stick to creating Uri object or if you care about performance use something similar to this one:

    public class UriHelpers
    {
        public static string GetFileNameFromUrl(string url)
        {
            string lastSegment = url.Split('/').Last();

            return lastSegment.Substring(0, lastSegment.IndexOf('?') < 0 ? lastSegment.Length : lastSegment.IndexOf('?'));
        }
    }
