Комментарии

Для успешной десериализации текущая координата в потоке должна находиться в начале графа объекта.For successful deserialization, the current position in the stream must be at the beginning of the object graph.

Deserialize(Stream, HeaderHandler)

handler
HeaderHandler

Делегат, используемый для обработки всех заголовков, найденных в потоке.Delegate to handle any headers found on the stream. Может иметь значение null.Can be null.

Комментарии

Заголовки используются только для конкретных приложений удаленного взаимодействия.Headers are used only for specific remoting applications. HeaderHandler Параметр является одним из двух способов возврата заголовков из потока в формате SOAP (RPC).The HeaderHandler parameter is one of two ways to return headers from a stream in SOAP Remote Procedure Call (RPC) format. Другой способ — использовать TopObject свойство.The other way is to use the TopObject property.

Для успешной десериализации текущая координата в потоке должна находиться в начале графа объекта.For successful deserialization, the current position in the stream must be at the beginning of the object graph.
