TaskItems2.Item 方法

傳回 TaskItems 集合的索引成員。

命名空間:  EnvDTE80
組件:  EnvDTE80 (在 EnvDTE80.dll 中)

語法

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

參數

  • index
    類型:Object

    必要項。 所要傳回項目的索引。

傳回值

類型: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 如何:編譯和執行 Automation 物件模型程式碼範例
