SPContentTypeId.CompareTo method
比較目前的內容類型識別碼 (ID) 與其他內容類型識別碼。
Namespace: Microsoft.SharePoint
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
Syntax
'宣告
Public Function CompareTo ( _
id As SPContentTypeId _
) As Integer
'用途
Dim instance As SPContentTypeId
Dim id As SPContentTypeId
Dim returnValue As Integer
returnValue = instance.CompareTo(id)
public int CompareTo(
SPContentTypeId id
)
參數
id
Type: Microsoft.SharePoint.SPContentTypeId內容類型識別碼，若要比較目前的內容類型識別碼。如果引數為另一種類型的物件，則此方法會擲回ArgumentException 。
傳回值
Type: System.Int32
整數，指出要比較的物件的相對順序。傳回的值可以是其中一下列含義：
值 |
意義 |
|---|---|
小於零 |
目前的內容類型識別碼小於做為引數傳遞的識別碼。 |
零 |
兩個內容識別碼相等。 |
大於零 |
目前的內容類型識別碼大於做為引數傳遞的識別碼。 |
備註
使用此方法來比較兩個內容類型識別碼。請注意基底的內容類型的識別碼較小的值大於衍生自它的任何內容類型的識別碼。
Examples
下列範例會顯示列印類似於在 [網站內容類型庫] 清單的方式組織的網站內容類型清單的主控台應用程式。輸出會先排序，依內容類型] 群組中，然後依內容類型識別碼。若要完成排序，範例會實作IComparer介面。實作先比較兩個內容類型的群組名稱。如果名稱相同，然後將比較內容類型識別碼呼叫SPContentTypeId類別之CompareTo方法。
