DtsWarnings.Contains メソッド
例外がスローされることなく、インデックスを使用してコレクション内の項目にアクセスできるかどうかを示す Boolean を返します。
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 Function Contains ( _
index As Object _
) As Boolean
'使用
Dim instance As DtsWarnings
Dim index As Object
Dim returnValue As Boolean
returnValue = instance.Contains(index)
public bool Contains(
Object index
)
public:
bool Contains(
Object^ index
)
member Contains :
index:Object -> bool
public function Contains(
index : Object
) : boolean
パラメーター
- index
型: System.Object
コレクション内で検索する名前、ID、またはインデックスです。
戻り値
型: System.Boolean
名前、ID、またはインデックスを使用してコレクションにアクセスできるかどうかを示す Boolean です。値が true の場合は、構文 DtsWarnings[index] でコレクションにアクセスできます。値が false の場合は、インデックスを使用して DtsWarnings コレクションから項目を取得することができません。
使用例
次のコード例では、メール送信タスクを作成し、パッケージに追加します。 メール送信タスクに必要なすべてのプロパティが設定されているわけではないため、パッケージの実行時に DtsErrors コレクションおよび DtsWarnings コレクションでエラーと警告が発生します。 DtsWarnings[index] 構文を使用してコレクションにアクセスできるかどうかを調べるには、Contains メソッドを使用します。コレクションにアクセスできる場合は、この構文を使用して一部のプロパティを取得します。
