适用于
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
。
返回
反序列化的图形的顶级对象(根)。
实现
例外
serializationStream
为 null
。
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。
