В следующей таблице представлены исходные значения свойств экземпляра класса SoapFormatter.The following table shows the initial property values for an instance of SoapFormatter.

Свойство.Property ЗначениеValue
SurrogateSelector null
Context Новая StreamingContext инициализация для указания того, что сериализованные данные могут быть переданы или получены из любого из других контекстов.A new StreamingContext initialized to specify that the serialized data can be transmitted to or received from any of the other contexts

Параметры

selector
ISurrogateSelector ISurrogateSelector ISurrogateSelector ISurrogateSelector

Поставщик приемников ISurrogateSelector, который используется для нового экземпляра SoapFormatter.The ISurrogateSelector to use with the new instance of SoapFormatter. Может иметь значение null.Can be null.

context
StreamingContext StreamingContext StreamingContext StreamingContext

StreamingContext, которому принадлежат источник и назначение сериализации.The StreamingContext that holds the source and destination of the serialization. Если параметр context имеет значение null, Context по умолчанию принимает значение CrossMachine.If the context parameter is null, then the Context defaults to CrossMachine.

Комментарии

Объекты сериализуются в или десериализуются из указанного Streamобъекта.Objects are serialized to, or deserialized from, the specified Stream.

Процесс сериализации или десериализации использует указанный ISurrogateSelector для поиска суррогатов, зарегистрированных для типов объектов, которые требуется десериализовать.The serialization or deserialization process uses the specified ISurrogateSelector to search for surrogates that are registered for the object types you want to deserialize. Суррогаты — это вспомогательные методы для сериализации и десериализации объектов конкретных классов.Surrogates are helpers that serialize and deserialize objects of specific classes. По умолчанию ISurrogateSelector невозможно выполнить сериализацию объектов, производных от, в MarshalByRefObject целях удаленного взаимодействия.The default ISurrogateSelector cannot handle the serialization of objects that derive from the MarshalByRefObject for remoting purposes. В ситуации удаленного взаимодействия указанное ISurrogateSelector значение заменяет объект, производный от MarshalByRefObject ObjRef , объектом, который сериализуется указанным суррогатным селектором.In a remoting situation the specified ISurrogateSelector replaces the object derived from MarshalByRefObject with a ObjRef object that is serialized by the specified surrogate selector. Поэтому, если вы хотите использовать удаленные объекты, присвойте selector параметру RemotingSurrogateSelectorэкземпляр.Therefore, if you want to use remote objects, set the selector parameter to an instance of RemotingSurrogateSelector. Если суррогаты не требуются, присвойте selector параметру nullзначение.If you do not need surrogates, set the selector parameter to be null.
