TaskInfos.Item[Object] 屬性

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

屬性值

TaskInfo 物件。

範例

以下程式碼範例是利用兩種方法從集合中取得一個項目。 第一種方法是利用語 tInfos[0] 法擷取集合中位於第一位置的整個物件並將其放入物件中 tInfo 。 你現在可以像平常一樣從物件中取得所有屬性 tInfo 。 第二種方法示範如何從集合中的第一個物件取得特定屬性。

範例輸出：

第一個提供者的任務 ID 為：{8FE4A9F8-D077-436B-9B00-C1EEAEFAFE55}

第一個任務名稱為：執行套件任務

備註

如果呼叫 Contains 方法回傳 true，你可以透過語法 TaskInfos[index]存取集合中指定的元素。 然而，若呼叫 方法 Contains 回傳 false，此特性會拋出例外。 在 C# 中，這個屬性就是類別的 TaskInfos 索引器。
