備註

內容類型被設計來幫助使用者更有意義的方式組織其 SharePoint 內容。內容類型是內容的可重複使用設定集合,您想要套用至某個特定類別。內容類型可讓您集中式、 可重複使用的方式管理中繼資料和行為的文件或項目型別。

如需詳細資訊,請參閱Introduction to Content Types

Examples

下列範例是一個主控台應用程式,會建立內容型別,並將它加入至網站內容的型別集合。接下來,範例會建立一個欄位 (欄),並連結至新的內容類型的欄位。最後,範例會建立清單,並將新的內容類型加入至屬於清單內容的型別集合。

之前執行的應用程式,您必須將Microsoft.Sharepoint.dll的參考加入至您的專案。
