The Black Knight Sings

This is just a small Utility requested on one of the SharePoint Newsgroups

It uses the UserGroup web service to list all the SharePoint Groups a user belongs to in a specified Site Collection

It's a small console application which requires two parameters:
···The first parameter is the Url of the site collection including protocol (example: http://localhost)
···The second parameter is the full username including Domain (example: MOSSWORK\user)

using System.IO;

namespace ListUsersGroups
{
    class Program
    {
        static int Main(string[] args)
        {
            if (args.Length < 2)
                return help();
            try
            {
                UserGroup usergroup = new UserGroup();
                usergroup.UseDefaultCredentials = true;
                usergroup.Url = args[0]+"/_vti_bin/usergroup.asmx";
                XmlNode groupXml =usergroup.GetGroupCollectionFromUser(args[1]);
                XmlDocument doc = new XmlDocument();
                doc.Load(new XmlNodeReader(groupXml));
                XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable);
                nsmgr.AddNamespace("sp", "http://schemas.microsoft.com/sharepoint/soap/directory/");
                foreach (XmlNode group in doc.SelectNodes("//sp:Groups/sp:Group", nsmgr))
                    Console.WriteLine(group.Attributes["Name"].Value);
            }

            {

            }
            return 0;
        }

        private static int help()
        {
            Console.WriteLine(@"{0} ", Path.GetFileNameWithoutExtension(Environment.GetCommandLineArgs()[0]));
            Console.WriteLine(@"  Site-url: Url of site collection including protocol (example http://localhost)");
            Console.WriteLine(@"  username: Full username including domain (example MOSSWORK\user)");
            return -1;
