我有一个 winform C# 应用程序，用作库存管理系统并在 eBay 拍卖上发布商品。我们正在尝试添加零件的兼容性，当尝试修改列表以添加兼容性信息时，我收到以下错误：

ConditionID（已添加）：Sandbox 中的一些类别支持 ConditionID。从 2010 年 5 月开始，它将在大多数类别的生产中发挥作用。当 GetCategoryFeatures 显示商品主要类别的 ConditionEnabled=Enabled 或必需时，使用 ConditionID 而不是 AttributeSetArray、LookupAttributeArray 或 ItemSpecifics 来指定项目的条件。
