ForEachVariableMapping.ID Eigenschaft

Definition

Ruft eine Zeichenfolge ab, die die eindeutige ID enthält, die der Variablen zugewiesen ist. Dies ist normalerweise eine GUID. Diese Eigenschaft ist schreibgeschützt.

public:
 property System::String ^ ID { System::String ^ get(); };
[Microsoft.SqlServer.Dts.Runtime.Localization.LocalizablePropertyDescription(typeof(Microsoft.SqlServer.Dts.Runtime.Localized), "IDDesc")]
public string ID { get; }
[<Microsoft.SqlServer.Dts.Runtime.Localization.LocalizablePropertyDescription(typeof(Microsoft.SqlServer.Dts.Runtime.Localized), "IDDesc")>]
member this.ID : string
Public ReadOnly Property ID As String

Eigenschaftswert

Eine Zeichenfolge, die eine eindeutige ID enthält, in der Regel eine GUID.

Im folgenden Codebeispiel wird eine ForEachVariableMapping, legt die Lese-/Schreibeigenschaften fest, zeigt die schreibgeschützten Eigenschaften an und richtet eine Zuordnung mithilfe der und ValueIndex der VariableName Eigenschaften ein.
