'宣告
Function Item ( _
index As Object _
) As TaskItem
TaskItem Item(
Object index
)
TaskItem^ Item(
[InAttribute] Object^ index
)
abstract Item :

function Item(
index : Object
) : TaskItem
參數
- index
型別:System.Object
必要項。所要傳回項目的索引。
傳回值
型別:EnvDTE.TaskItem
TaskItem 物件。
備註
傳遞給 Index 的值是整數,也就是物件在集合中的索引。然而對許多物件而言,Index 值也可以是等於集合中之物件的字串值。但是,Item 接受的實際值,會視集合及其實作而有所不同。
如果集合無法找到對應索引值的物件,Item 方法就會擲回 ArgumentException 例外狀況。
範例
這個範例會將兩個工作項目加入至工作清單中,並在訊息視窗中顯示這兩個項目的某些 Item 特定屬性。如需如何像執行增益集一般,執行這個範例的詳細資訊,請參閱 HOW TO:編譯和執行 Automation 物件模型程式碼範例。
