Item プロパティ

Executable オブジェクトをコレクションから返します。

名前空間:  Microsoft.SqlServer.Dts.Runtime
アセンブリ:  Microsoft.SqlServer.ManagedDTS (Microsoft.SqlServer.ManagedDTS.dll)

構文

'宣言
Public ReadOnly Default Property Item ( _
    index As Object _
) As Executable
    Get
'使用
Dim instance As Executables
Dim index As Object
Dim value As Executable

value = instance(index)

public Executable this[
    Object index
] { get; }

public:
property Executable^ default[Object^ index] {
    Executable^ get (Object^ index);
}

member Item : Executable

JScript はインデックス化されたプロパティの使用をサポートしていますが、新規の宣言はサポートしていません。

パラメーター

説明

Contains メソッドの呼び出しが true を返す場合、Executables[index] 構文を使用することにより、コレクション内の指定した要素にアクセスできます。Contains が false を返す場合、このプロパティは例外をスローします。C# の場合、このプロパティは Executables クラスのインデクサとなります。

使用例

次の例は、Remove で使用したサンプルを変更したものです。項目構文を使用して実行可能オブジェクトを削除します。

サンプルの出力 :

The first package contains 1 executables

The first package now contains 0 executables

The second package initially contains 0 executables

The second package now contains 1 executables
