オーバーロード

Deserialize(Stream)

指定したストリームをオブジェクト グラフに逆シリアル化します。Deserializes the specified stream into an object graph.

Deserialize(Stream, HeaderHandler)

指定したストリームをオブジェクト グラフに逆シリアル化します。Deserializes the specified stream into an object graph. そのストリーム内にヘッダーがある場合は、指定した HeaderHandler がそのヘッダーを処理します。The provided HeaderHandler handles any headers in that stream.

実装

例外

serializationStreamnull です。The serializationStream is null.

serializationStream はシークをサポートしていますが、長さが 0 です。The serializationStream supports seeking, but its length is 0.

または-or- ターゲット型は Decimal ですが、値が Decimal 型の範囲外です。The target type is a Decimal, but the value is out of range of the Decimal type.

注釈

逆シリアル化を正常に行うには、ストリーム内の現在位置がオブジェクトグラフの先頭にある必要があります。For successful deserialization, the current position in the stream must be at the beginning of the object graph.
