'用途
Dim instance As SPListItem
Dim value As Integer
value = instance.ID
public override int ID { get; }
Property value
Type: System.Int32
整數，識別清單項目。
備註
ID屬性的值不是清單項目集合中之項目的索引相同。此屬性包含的項目維整數識別碼，亦即一大於剛剛新增的項目 ID。刪除項目時，其識別碼不會重複使用。
ID屬性無效的項目，直到它已呼叫SPListItem.Update方法來保存到資料庫建立透過SPListItemCollection.Add方法。
Examples
下列範例會為主控台應用程式，逐一查看集合的清單項目，並列印集合，並與其ID屬性的值中的每個項目索引。從應用程式的輸出看起來可能類似如下：
Index = 0 ID = 1
Index = 1 ID = 4
Index = 2 ID = 5
Index = 3 ID = 6
Index = 4 ID = 7
