傳回 Windows 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 Window

Window Item(
    Object index
)

Window^ Item(
    [InAttribute] Object^ index
)

abstract Item : 
        index:Object -> Window

function Item(
    index : Object
) : Window

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.Window
Window 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於索引值的物件，Item 方法就會擲回 ArgumentException 例外狀況。

範例

這個範例會顯示 Windows2 集合中所有項目的標題。

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。
