Wyjątki

Element serializationStream to null.

-lub- Wartość graph ma wartość null.

Wystąpił błąd podczas serializacji, na przykład jeśli obiekt w parametrze graph nie jest oznaczony jako serializowalny.

Obiekt wywołujący nie posiada wymaganych uprawnień.

ASP.NET Core 5 lub nowszych: zawsze zgłaszany, chyba że BinaryFormatter funkcja zostanie ponownie włączona w pliku projektu. Aby uzyskać więcej informacji, zobacz Rozwiązywanie błędów binarnychFormatter obsoletion i wyłączanie.

Serialize(Stream, Object, Header[])

Serializuje obiekt lub graf obiektów z określonym górnym (głównym) do danego strumienia dołączającego podane nagłówki.

public:
 virtual void Serialize(System::IO::Stream ^ serializationStream, System::Object ^ graph, cli::array <System::Runtime::Remoting::Messaging::Header ^> ^ headers);

override this.Serialize : System.IO.Stream * obj * System.Runtime.Remoting.Messaging.Header[] -> unit
Public Sub Serialize (serializationStream As Stream, graph As Object, headers As Header())

Parametry

serializationStream
Stream

Strumień, do którego ma zostać zserializowany obiekt.

graph
Object

Obiekt w katalogu głównym grafu do serializacji.

headers
Header[]

Komunikacja zdalna nagłówków do uwzględnienia w serializacji. Może to być null.

Implementuje

Wyjątki

Element serializationStream to null.

Wystąpił błąd podczas serializacji, na przykład jeśli obiekt w parametrze graph nie jest oznaczony jako serializowalny.

Obiekt wywołujący nie posiada wymaganych uprawnień.

Uwagi

Proces serializacji zawiera informacje podane w parametrze headers na początku serializowanego strumienia.

Nagłówki są używane tylko w przypadku określonych aplikacji do komunikacji zdalnie.
