Deserialize(Stream, HeaderHandler)

将流反序列化为对象图形，该流中的任何标题都由给定的 HeaderHandler 进行处理。

public:
 virtual System::Object ^ Deserialize(System::IO::Stream ^ serializationStream, System::Runtime::Remoting::Messaging::HeaderHandler ^ handler);

public object Deserialize (System.IO.Stream serializationStream, System.Runtime.Remoting.Messaging.HeaderHandler handler);

abstract member Deserialize : System.IO.Stream * System.Runtime.Remoting.Messaging.HeaderHandler -> obj
override this.Deserialize : System.IO.Stream * System.Runtime.Remoting.Messaging.HeaderHandler -> obj

Public Function Deserialize (serializationStream As Stream, handler As HeaderHandler) As Object

参数

serializationStream: Stream

包含要反序列化的数据的流。

handler: HeaderHandler

对在流中发现的任何标题进行处理的委托。可以为 null。

Object

反序列化的图形的顶级对象（根）。

实现

Deserialize(Stream, HeaderHandler)

例外

ArgumentNullException

serializationStream 为 null。

SerializationException

serializationStream 支持查找，其长度为 0。

注解

标头仅用于特定的远程处理应用程序。参数 HeaderHandler 是从 SOAP 远程过程调用 (RPC) 格式的流中返回标头的两种方法之一。另一种方法是使用 TopObject 属性。

若要成功反序列化，流中的当前位置必须位于对象图的开头。

TimeSpan 对象根据 ISO 8601：1998 第 5.5.3.2.1 节“备用”标准进行序列化。
