ASP.NET-Active Direcotry编程示例

查找指定的AD帐号

using (DirectoryEntry de = new DirectoryEntry("LDAP://RootDSE"))
 {
          string DCName = (string)de.Properties["defaultNamingContext"][0];

          using (DirectoryEntry DC = new DirectoryEntry("LDAP://" + DCName))
          {
                   using (DirectorySearcher deSearch = new DirectorySearcher( ))
                   {
                            deSearch.SearchRoot = DC;
                            deSearch.SearchScope = SearchScope.Subtree;
                            deSearch.Filter = "(&(&(objectCategory=person)(objectClass=user))(sAMAccountName=" + myAccountName+ "))";
                            using (SearchResultCollection results = deSearch.FindAll( ))
                            {
                                if (results.Count == 0)
                                {
                                    return false;
                                }
                                return true;
                            }
                     }
            }
}

如何使用DirectoryEntry的长构造函数

   using (DirectoryEntry group = DirectoryEntry(ADPath, ADUser, ADPassword, AuthenticationTypes.Secure))
            {
                string filter = "(objectClass=Group)";
                string[ ] properties = new string[ ] ...{ "cn", "displayname", "distinguidshedName" };
                using (DirectorySearcher search = new DirectorySearcher(group, filter, properties, SearchScope.Base))
                {
                    search.AttributeScopeQuery = "member";
                    using (SearchResultCollection results = search.FindAll( ))
                    {

                        for (int i = 0; i < results.Count; i++)
                        {
                            using (DirectoryEntry de = results[i].GetDirectoryEntry( ))
                            {
                                // add your process code....

                            }
                        }
                    }
                }
            }
