SoapFormatter.Deserialize メソッド (Stream)

2008-03-28

指定されたストリームのデータを逆シリアル化し、オブジェクトのグラフを再構成します。

Overloads Public Overridable Function Deserialize( _
   ByVal serializationStream As Stream _) As Object Implements IFormatter.Deserialize
[C#]
public virtual object Deserialize(StreamserializationStream);
[C++]
public: virtual Object* Deserialize(Stream* serializationStream);
[JScript]
public function Deserialize(
   serializationStream : Stream) : Object;

パラメータ

serializationStream
逆シリアル化するデータを含んでいるストリーム。

戻り値

逆シリアル化されたグラフの先頭 (ルート) オブジェクト。

実装

IFormatter.Deserialize

例外

例外の種類	条件
ArgumentNullException	serializationStream が null 参照 (Visual Basic では Nothing) です。

解説

メモ逆シリアル化を正常に実行するには、ストリーム内の現在の位置をオブジェクトグラフの先頭にする必要があります。
