「良い」解決策がなかったので、私は私のことをしました:-)ライブラリを作成するためだけにライブラリを作成する必要がありました:FluentSerializer。ライブラリを使用して、バイナリデータをシリアル化する方法の「説明」を作成できます。この説明は流暢な表記で書かれています。あなたは(私が書いた他のライブラリ、FluentStatementを通してwhile
)あなたの流暢な説明にif
、、 ...のようなすべての通常のステートメントを含めることができfor
ます(明らかに流暢な表記を使用しています)。次に、記述は式ツリーとしてコンパイルされ、次に動的メソッドのグループ(Serialize、Deserialize、およびSize(シリアル化されたデータの))としてコンパイルされます。

明らかに、このライブラリは、大量のデータをシリアル化/逆シリアル化する必要がある場合にのみ有効です。シリアル化/逆シリアル化するオブジェクトが1つしかない場合は、おそらくBinaryReader
/BinaryWriter
で十分です(元の質問で私が提案し、彼の回答でFantiusが提案したように)。
