備註
用於此類別為基底類別建立保存SharePoint Foundation伺服器陣列，會將自訂的非資料庫內容元件的相關資訊傳遞至SharePoint Foundation VSS 編寫器服務(有時稱為 SPF 編寫器服務) 的子物件。
您也必須建立自訂的非資料庫元件的 VSS 編寫器。
自訂資料庫元件只需要在伺服器陣列設定資料庫中註冊。SharePoint VSS 編寫器服務，包括其以及陰影複製的原生SharePoint Foundation資料庫中沒有內建的 VSS 編寫器。據以，您不需要建立的 VSS 編寫器，也不需要從SPVssDiscoveryHelper或SPVssComponentDefinition資料庫元件的衍生類別。
