C# - Get Vimeo ID from Vimeo Url

I use this method to get only Vimeo Id in Vimeo Url :
string VimeoUrl = "https://vimeo.com/xxxxxx";
Match vimeoMatch = VimeoVideoRegex.Match(VimeoUrl);
string VdoId = string.Empty;
if (vimeoMatch.Success)
       VdoId = vimeoMatch.Groups[1].Value;

public static readonly Regex VimeoVideoRegex = new Regex(@"vimeo\.com/(?:.*#|.*/videos/)?([0-9]+)", RegexOptions.IgnoreCase | RegexOptions.Multiline);
