TaskInfos.Item[Object] 屬性

定義

從集合中擷取 TaskInfo

public:
 property Microsoft::SqlServer::Dts::Runtime::TaskInfo ^ default[System::Object ^] { Microsoft::SqlServer::Dts::Runtime::TaskInfo ^ get(System::Object ^ index); };
public Microsoft.SqlServer.Dts.Runtime.TaskInfo this[object index] { get; }
member this.Item(obj) : Microsoft.SqlServer.Dts.Runtime.TaskInfo
Default Public ReadOnly Property Item(index As Object) As TaskInfo

參數

index
Object

要從集合中擷取之 TaskInfo 的名稱、識別碼或索引。

屬性值

TaskInfo

TaskInfo 物件。

範例

下列程式碼範例會使用兩個方法,從集合中抓取專案。 第一個方法會使用 tInfos[0] 語法來抓取位於集合第一個位置的整個物件,並將它放在物件中 tInfo 。 您現在可以如往常般從物件取出所有屬性 tInfo 。 第二個方法示範如何從集合中的第一個物件抓取特定屬性。

範例輸出:

第一個提供者的工作識別碼是: {8FE4A9F8-D077-436B-9B00-C1EEAEFAFE55}

第一個工作的名稱為:執行封裝工作

備註

如果對方法的呼叫傳回 Contains true ,您可以使用語法來存取集合中的指定元素 TaskInfos[index] 。 不過,如果對方法的呼叫傳回 Contains ,則這個屬性會擲回 false 例外狀況。 在 C# 中,這個屬性是 TaskInfos 類別的索引子。
