SurrogateSelector null

适用于

SoapFormatter(ISurrogateSelector, StreamingContext)

使用指定的SoapFormatterISurrogateSelector. 初始化类的新实例StreamingContext

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)

参数

selector
ISurrogateSelector

ISurrogateSelector 新实例一起使用的 SoapFormatter。 可以为 null

context
StreamingContext

StreamingContext保存序列化的源和目标。 如果参数 contextnull,则 Context 默认值为 CrossMachine

注解

对象被序列化为指定的 Stream对象或反序列化对象。

序列化或反序列化过程使用指定的 ISurrogateSelector 来搜索为要反序列化的对象类型注册的代理项。 代理项是序列化和反序列化特定类对象的帮助程序。 默认值 ISurrogateSelector 无法处理从远程 MarshalByRefObject 处理目的派生的对象序列化。 在远程处理情况下,指定的ISurrogateSelector对象将替换为MarshalByRefObjectObjRef由指定代理项选择器序列化的对象。 因此,如果要使用远程对象,请将 selector 参数设置为实例 RemotingSurrogateSelector。 如果不需要代理项,请将 参数设置为 < a0/>。
