Using Arrays with Classes

Hi,

I have the following code that will search through Active Directory and return users to a DataTable.

string[] rowArrary = new string[userProperties.Length];
                foreach (SearchResult searchResult in results)
                {
                    for (int i = 0; i < userProperties.Length; i++)
                    {
                        if (searchResult.Properties.Contains(userProperties[i]))
                        {
                            userDetails[i] = searchResult.Properties[userProperties[i]][0].ToString();
                        }
                        rowArrary[i] = userDetails[i];
                    }
                    table.Rows.Add(rowArrary);
                }

userProperties is an array of all the properties I am searching for in Active Directory and userDetails is the class I have for each returned employee. The code works, but the problem is because I'm putting it in an array, I cannot change the returned values in the class. For instance, the Manager vaule I have a function to modify the DN to show the DisplayName.

public string Manager
         {
             get { return _manager; }
             set { _manager = GetUserByDN(value); }
         }

Code I have for the GetUserByDN method.

public static string GetUserByDN(string dn)
         {
            SearchResult results = null;
            try
            {
                string path = LDAP://DOMAIN;
                DirectoryEntry entry = new DirectoryEntry(path);
                DirectorySearcher search = new DirectorySearcher(entry);
                //search.Filter = "(&(objectClass=user)(anr=" + fullCN + "))";
                search.Filter = "(&(objectClass=user)(distinguishedname=" + dn + "))";
                results = search.FindOne();
                if (results != null)
                {
                    search.PropertiesToLoad.Add(ADProperties.DISPLAYNAME);
                    return results.Properties[ADProperties.DISPLAYNAME][0].ToString();
                }
                else
                {
                    return null;
                }
            }
            catch (Exception ex)
            {
                string debug = ex.Message;
                return null;
            }

I have other returned Active Directory properties I would like to modify. What is the best way to accomplish. I'm thinking I need to rework my code from the beginning.

Thanks,

A
