DirectoryEntry的属性测试代码

 public static DirectoryEntry FindOneDirectoryEntry(string strDomainName, string strFilter, SearchScope scSearchScope)
        {
            dbMessage = new dbAccessMessage();
            AdInfo adinfo = Config.GetConfig(strDomainName);
            DirectoryEntry de = null;
            try
            {
                string path = "LDAP://" + adinfo.DomainControler + "/" + Utility.GetDomainDN(adinfo.RootDn);
                DirectoryEntry root = new DirectoryEntry(path, adinfo.SuperUserName, adinfo.SuperUserPass);
                DirectorySearcher srch = new DirectorySearcher();
                srch.SearchRoot = root;
                srch.Filter = strFilter;
                srch.SearchScope = scSearchScope;
                SearchResult sr = srch.FindOne();

                if (sr != null)
                {

                    de = sr.GetDirectoryEntry();
                }

            }
            catch
            {
            }
            return de;
        }

aspx.cs

        if (!Page.IsPostBack)
        {
            DirectoryEntry de = Utility.FindOneDirectoryEntry(strDomainName,strFilter,scSearchScope);
            AdUserInfo aduserinfo=new AdUserInfo();
            foreach (string property in de.Properties.PropertyNames)
            {
                /*
                PropertyValueCollection valueCollection = de.Properties[property];
                for (int i = 0; i < valueCollection.Count; i++)
                {
                    msg.Text += property + ":" + valueCollection[i].ToString()+"<br/>";
                }
                 * */
                msg.Text += property + ":" + de.Properties[property].Value.ToString()+ "<br/>";
            }
            //aduserinfo = ADUser.GetUserInfo(de); ;
            msg1.Text = aduserinfo.sAMAccountName;
        }

注释代码的返回结果：

objectClass:top
objectClass:domain
objectClass:domainDNS

方法二的返回结果：

objectClass:System.Object[]

两个之间的关系是什么呢？至今未弄清楚。
