c# - シリアル化の問題

Question

シリアル化に問題があります。正当な理由でメソッドをシリアル化できないことを理解しているので、既存のクラスをより管理しやすいクラスに変換するファクトリ クラスを作成しました。

これは元のクラスです:

using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.ComponentModel.DataAnnotations;
using System.Linq;

これは私のファクトリーメソッドです：

            UserId = Object.UserId,
            UserName = Object.UserName,
            CompanyId = Object.GetCompanyId(),
            Description = Object.Description,
            Tags = Object.Tags,
            DateCreated = Object.DateCreated,
            Path = Object.GetBaseDirectory,

            ThumbnailName = Object.ThumbNail
        };

        return FactoryObject;
    }

これは私の audittrailmanager クラスの一部です:

            return (Xml.ToString());

    private static SerialisedAsset AssetFactory(Assets.Asset Object)

私がやろうとしているのは、作業中のオブジェクト (この場合は資産) を記録する監査証跡を作成し、クラスをシリアル化し、レポートなどで使用するためにデータベースに挿入することです。

私の質問は; これはそれを行う方法です。より良い方法はありますか？
