  • 發行項

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
    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。

實作

TaskItems.Item(Object)

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。

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。
