Configurations.Contains(Object) Méthode

Définition

Espace de noms:

Microsoft.SqlServer.Dts.Runtime

Assembly:

Microsoft.SqlServer.ManagedDTS.dll

Retourne un booléen qui indique si les éléments de la collection peuvent être consultés par un index sans jeter d’exception.

public:
 bool Contains(System::Object ^ index);

public bool Contains(object index);

member this.Contains : obj -> bool

Public Function Contains (index As Object) As Boolean

Paramètres

index

Object

Le nom, l’identité, l’ID ou l’index de l’objet Configuration à localiser dans la collection.

Retours

Boolean

Un booléen qui indique si la collection peut être accessible par nom, identité, identifiant ou index. Une valeur de true indique que la collection peut être accessible en utilisant la syntaxe Configurations[index]. Une valeur de false indique que l’indexation ne peut pas être utilisée pour récupérer des éléments de la Configurations collection ; utiliser cette propriété crée une exception.

Exemples

L’exemple de code suivant utilise la Contains méthode pour vérifier si la syntaxe des éléments est disponible.
