Directory Entry/ Directory Searcher question

Hello -

I am in a situation where I wish to gather information thru the Active Directory Domain:

DirectoryEntry entry = new DirectoryEntry();
entry.Path = "LDAP://DC=xxxx"
entry.AuthenticationType = AuthenticationTypes.Secure;

DirectorySearcher search = DirectorySearcher(entry);
search.PropertiesToLoad.Add("givenName");
search.PropertiesToLoad.Add("memberof");
search.PropertiesToLoad.Add("sAMAccountName");

SearchResultCollection result = search.FindAll();

So far everything works fine.  Returns some 1163 entries.  What I want to do now is loop through the entries and gather the individual values for givenName, memberof, etc.

foreach (SearchResult sr in result)
{
  *****************************************
  strName = sr.Properties["givenName"].ToString();
  this statement stores the literal
  "System.DirectoryServices.ResultPropertyValueCollection"
  in the local string variable strName
  ***********************************
}

What the heck am I missing?

Thanks in advance...
