Açıklamalar

Aşağıdaki tablo, SoapFormatter öğesinin bir örneği için başlangıç özellik değerlerini gösterir.

Özellik	Değer
SurrogateSelector	null
Context	Seri hale getirilmiş verilerin diğer bağlamlardan herhangi birine iletilebileceğini veya alınabileceğini belirtmek için yeni StreamingContext bir başlatıldı

SoapFormatter(ISurrogateSelector, StreamingContext)

belirtilen ISurrogateSelector ve StreamingContextile sınıfının yeni bir örneğini SoapFormatter başlatır.

public:
 SoapFormatter(System::Runtime::Serialization::ISurrogateSelector ^ selector, System::Runtime::Serialization::StreamingContext context);

public SoapFormatter (System.Runtime.Serialization.ISurrogateSelector selector, System.Runtime.Serialization.StreamingContext context);

Public Sub New (selector As ISurrogateSelector, context As StreamingContext)

Parametreler

selector

ISurrogateSelector

ISurrogateSelector yeni örneğiyle kullanılacak.SoapFormatter olabilir null.

context

StreamingContext

Serileştirmenin StreamingContext kaynağını ve hedefini tutan. context parametresi isenullContext, varsayılan olarak olurCrossMachine.

Açıklamalar

Nesneler belirtilen Streamöğesine seri hale getirilir veya 'den seri durumdan çıkarılır.

Seri hale getirme veya seri durumdan çıkarma işlemi, seri durumdan çıkarılmasını istediğiniz nesne türleri için kayıtlı yedekleri aramak için belirtilen ISurrogateSelector öğesini kullanır. Vekiller, belirli sınıfların nesnelerini seri hale getiren ve seri durumdan çıkaran yardımcılardır. Varsayılan, ISurrogateSelector uzaktan iletişim amacıyla 'den türetilen nesnelerin serileştirmesini MarshalByRefObject işleyemez. Uzaktan iletişim durumunda, belirtilen ISurrogateSelector öğesinden MarshalByRefObject türetilen nesneyi belirtilen vekil seçici tarafından seri hale getirilmiş bir ObjRef nesneyle değiştirir. Bu nedenle, uzak nesneleri kullanmak istiyorsanız parametresini selector örneğine RemotingSurrogateSelectorayarlayın. Vekillere ihtiyacınız yoksa parametresini selector olarak nullayarlayın.
