SPContentTypeCollection.Add method

將內容類型加入至集合。

Namespace:  Microsoft.SharePoint
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

Syntax

'宣告
Public Function Add ( _
    contentType As SPContentType _
) As SPContentType
'用途
Dim instance As SPContentTypeCollection
Dim contentType As SPContentType
Dim returnValue As SPContentType

returnValue = instance.Add(contentType)

public SPContentType Add(
    SPContentType contentType
)

參數

• contentType
  Type: Microsoft.SharePoint.SPContentType

  要加入至集合的內容型別。

傳回值

Type: Microsoft.SharePoint.SPContentType
內容型別的完整初始化執行個體。

Exceptions

備註

內容型別未完全初始化之前加入至內容的型別集合。在其他方面，將它指派為相關集合的內容類型識別碼。例如，當您新增站台的內容類型與清單相關聯的內容型別集合，結果清單的內容型別會有不同於原始網站的內容型別的內容型別 ID。如需詳細資訊，請參閱Site and List Content Types。

Examples

下列範例會顯示主控台應用程式，從AvailableContentTypes屬性所傳回的集合中取得內容型別。接著，它會加入該內容的型別由SPList物件的 [ ContentTypes ] 屬性所傳回的集合。
