Osservazioni
The value for the Nullable property has a corresponding NullableSpecified property in the Reporting Service Execution Web service proxy class. Because Nullable is read-only and cannot be set by end users, you do not need to specify this property. For more information about specifying properties, see Omissione di valori per gli oggetti del servizio Web facoltativi.
