Configurations.Item[Object] 屬性

public:
 property Microsoft::SqlServer::Dts::Runtime::Configuration ^ default[System::Object ^] { Microsoft::SqlServer::Dts::Runtime::Configuration ^ get(System::Object ^ index); };

public Microsoft.SqlServer.Dts.Runtime.Configuration this[object index] { get; }

member this.Item(obj) : Microsoft.SqlServer.Dts.Runtime.Configuration

參數

屬性值

Configuration 物件。

範例

以下程式碼範例使用該 Contains 方法來查看項目語法是否可用。 若 true，則程式碼範例使用 項目 p.Configurations[0].Name 語法取得集合首位（索引位置 0）的配置名稱。

範例輸出：

備註

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