備註

下表顯示 SoapFormatter 執行個體的初始屬性值。

屬性	值
SurrogateSelector	`null`
Context	已初始化的新 StreamingContext ，指定串行化數據可以傳輸至任何其他內容或從任何其他內容接收

適用於

SoapFormatter(ISurrogateSelector, StreamingContext)

使用指定的 SoapFormatter 和 ISurrogateSelector，初始化 StreamingContext 類別的新執行個體。

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

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

new System.Runtime.Serialization.Formatters.Soap.SoapFormatter : System.Runtime.Serialization.ISurrogateSelector * System.Runtime.Serialization.StreamingContext -> System.Runtime.Serialization.Formatters.Soap.SoapFormatter

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

參數

selector: ISurrogateSelector

要與 ISurrogateSelector 新執行個體一起使用的 SoapFormatter。可以是 null。

context: StreamingContext

StreamingContext，保留序列化的來源和目的地。如果 context 參數為 null，那麼 Context 會預設為 CrossMachine。

備註

物件會串行化至指定的 Stream，或從還原串行化。

串行化或還原串行化程式會使用指定的 ISurrogateSelector 來搜尋針對您要還原串行化之物件類型所註冊的 Surrogate。 Surrogates 是可串行化和還原串行化特定類別對象的協助程式。默認值 ISurrogateSelector 無法處理衍生自 MarshalByRefObject 的物件串行化，以供遠端處理。在遠程的情況下，指定的 ISurrogateSelector 會以指定的 Surrogate 選取器串行化的物件取代衍生自 MarshalByRefObject ObjRef 的物件。因此，如果您想要使用遠程物件，請將 selector 參數設定為的 RemotingSurrogateSelector實例。如果您不需要 Surrogates，請將 selector 參數設定為 null。
