この種のタスクを実行するには、 System.DirectoryServices 名前空間を使用します（ DirectoryServicesはLDAP用の管理されたラッパーです）。
Try

You can use a search string such as "(&(objectCategory=user)(objectClass=person)(sAMAccountName=" + userId + "))" to search for a user (userID would need to be replaced with the User's ID).
すべてをまとめて結合するには、以下のスニペットを修正してユーザーのすべてのプロパティを表示します。ユーザー名にのみフォーカスするように調整できます。
