How to find users in AD that belong to a group, and just get their SAMAccountName, and SID?

I just want a user to be able to type in a group name in a textbox, and return just their login name and their SID.

So far i have this, and that loads the users in the group but im unsure how to extract the login and SID.

 SearchResult result;
            DirectorySearcher search = new DirectorySearcher();
            search.Filter = String.Format("(cn={0})", txtGroup.Text);
            search.PropertiesToLoad.Add("member");
            search.PropertiesToLoad.Add("cn");
            search.PropertiesToLoad.Add("objectGUID");
            result = search.FindOne();


            StringBuilder userNames = new StringBuilder();
            if (result != null)
            {
                for (int counter = 0; counter <
                result.Properties["member"].Count; counter++)
                {
                    string user = (string)result.Properties["member"][counter];
                    userNames.AppendLine(user);

                }
            }
            lblResults.Text = userNames.ToString();

I think it would work better if you reverse your query:

(&(objectClass=user)(memberOf={0}))

This way you'll directly get back a list of users by using FindAll. Don't forget to add sAMAccountName etc into PropertiesToLoad.

The propertie wich contains SID is called objectSid, and the propertie wich contain th login is sAMAccountName for the NT4 compatible version and userPrincipalName. You'd better work with @Virkkunen advice.

static void Main(string[] args)
{
  /* Connection to Active Directory
   */
  DirectoryEntry deBase = new DirectoryEntry("LDAP://192.168.183.138:389/dc=societe,dc=fr", "administrateur", "pwd");

  /* Directory Search
   */
  DirectorySearcher dsLookForGrp = new DirectorySearcher(deBase);
  dsLookForGrp.Filter = String.Format("(cn={0})", "yourgroup");
  dsLookForGrp.SearchScope = SearchScope.Subtree;
  dsLookForGrp.PropertiesToLoad.Add("distinguishedName");
  SearchResult srcGrp = dsLookForGrp.FindOne();

  /* Directory Search
   */
  DirectorySearcher dsLookForUsers = new DirectorySearcher(deBase);
  dsLookForUsers.Filter = String.Format("(&(objectCategory=person)(memberOf={0}))", srcGrp.Properties["distinguishedName"][0]);
  dsLookForUsers.SearchScope = SearchScope.Subtree;
  dsLookForUsers.PropertiesToLoad.Add("objectSid");
  dsLookForUsers.PropertiesToLoad.Add("userPrincipalName  ");
  dsLookForUsers.PropertiesToLoad.Add("sAMAccountName");
  SearchResultCollection srcLstUsers = dsLookForUsers.FindAll();

  foreach (SearchResult sruser in srcLstUsers)
  {
    Console.WriteLine("{0}", sruser.Path);

    SecurityIdentifier sid = new SecurityIdentifier((byte[])   sruser.Properties["objectSid"][0], 0);
    Console.WriteLine(sid.ToString());    

    foreach (string property in sruser.Properties.PropertyNames)
    {
      Console.WriteLine("\t{0} : {1} ", property, sruser.Properties[property][0]);
    }
  }
}
