若要成功還原串行化，數據流中的目前位置必須位於物件圖形的開頭。

適用於

Deserialize(Stream, HeaderHandler)

將資料流還原序列化至物件圖形中，使用指定的 HeaderHandler 處理該資料流中的任何標頭。

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

參數

serializationStream: Stream

資料流，包含要還原序列化的資料。

handler: HeaderHandler

委派，用於處理在資料流上找到的任何標頭。可以是 null。

傳回

Object

還原序列化圖形的最上層物件 (根)。

實作

Deserialize(Stream, HeaderHandler)

例外狀況

ArgumentNullException

serializationStream 為 null。

SerializationException

serializationStream 支援搜尋，且它的長度為 0。

備註

標頭僅用於特定遠端處理應用程式。參數 HeaderHandler 是兩種方式之一，可從SOAP遠端過程調用 (RPC) 格式的數據流傳回標頭。另一種方式是使用 TopObject 屬性。

若要成功還原串行化，數據流中的目前位置必須位於物件圖形的開頭。

TimeSpan 物件會根據 ISO 8601：1998 第 5.5.3.2.1 節「替代」標準進行串行化。
