ForEachVariableMapping.ValueIndex Propriété

Définition

Espace de noms:

Microsoft.SqlServer.Dts.Runtime

Assembly:

Microsoft.SqlServer.ManagedDTS.dll

Obtient ou définit dans le tableau l'index des énumérateurs qui prennent des collections pour valeur.

public:
 property System::Object ^ ValueIndex { System::Object ^ get(); void set(System::Object ^ value); };

public object ValueIndex { get; set; }

member this.ValueIndex : obj with get, set

Public Property ValueIndex As Object

Valeur de propriété

Object

Objet correspondant à l'index dans le tableau.

Exemples

L’exemple de code suivant crée un ForEachVariableMapping, définit les propriétés en lecture-écriture, affiche les propriétés en lecture seule et configure un mappage à l’aide des VariableName propriétés et ValueIndex des propriétés.
