Help with array

[Terry-OMAF]

I've created a method for a web service and it does exactly what I want it
to do but one thing. Instead of just returning a concatenated "givenName"
and "sn" I would like to be able to return an array that also has the users
email address. How would I do that?

[WebMethod]
public ArrayList getAllADDomainU sers()
{
string [] strAttrs = new
string[]{"givenName","s n","mail","SAMA ccountName","te lephoneNumber"} ;
ArrayList allUsers = new ArrayList();

DirectoryEntry searchRoot = new
DirectoryEntry( "LDAP://ou=peeps,ou=Min e,dc=on,dc=ca") ;
DirectorySearch er search = new DirectorySearch er(searchRoot);

search.PageSize = 500;
search.Filter = "(&(objectClass =user)(objectCa tegory=person)) ";
search.Properti esToLoad.AddRan ge(strAttrs);
search.Sort.Dir ection=SortDire ction.Ascending ;
search.Sort.Pro pertyName="sn";

SearchResult result;
SearchResultCol lection resultCol = search.FindAll( );

if (resultCol != null)
{
for(int counter=0; counter < resultCol.Count ; counter++)
{
result = resultCol[counter];
if (result.Propert ies.Contains("g ivenName") &&
result.Properti es.Contains("sn ") && result.Properti es.Contains("ma il"))
{
allUsers.Add(re sult.Properties["sn"][0].ToString() + ", " +
result.Properti es["givenName"][0].ToString());
//allUsers.Add(re sult.Properties["mail"][0].ToString());
}
}
}
return allUsers;
}
