Замечания
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 Пропуск значений для необязательных объектов веб-службы.
