ForEachVariableMapping.ID Proprietà

Definizione

Ottiene un valore String contenente l'ID univoco assegnato alla variabile. Si tratta in genere di un GUID. Questa proprietà è di sola lettura.

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
