Configurations.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 Configurations
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 Configuration オブジェクトの名前、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 Configurations[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 Configurations コレクションから項目を取得することができません。このプロパティを使用すると、例外がスローされます。
使用例
次のコード例では、Contains メソッドを使用して、項目構文が利用できるかどうかを確認します。

using Microsoft.SqlServer.Dts.Runtime;
namespace Configurations_API
{

{
static void Main(string[] args)
{

Configuration conf1 = p.Configurations.Add();
conf1.ConfigurationString = "Conf1 Configuration String";

Console.WriteLine("Name of configuration at position 0 is {0}", myName);
}
else
{
Console.WriteLine("Contains returned {0}", configContains);
}
