NHibernate泛型集合封装：Emit动态生成PersistentCollection实战在.NET数据访问层设计中，自定义集合类型是解决一对多关系重复编码的核心技术。其本质是通过泛型抽象（如ISet）解耦领域逻辑与持久化机制，利用动态代码生成（Emit）替代反射调用，实现零开销代理。该方案显著提升ORM集成效率，支撑Question-Answer、Order-Item等典型业务建模，并为领域驱动设计（DDD）中的聚合一致性提供基础设施保障。本文聚焦NHibernate场景下PersistentCollection的动态生成原理与工程落地，涵盖泛型约束设计、IL指令编写、线程安全委托构建及阅读详情



public ActionForward saveItemContents(ActionMapping mapping, ActionForm form,

				String id = obj.get("id").toString();

				String supplierNameFull = obj.get("supplierNameFull").toString();

				String companyProperty  = obj.get("companyProperty").toString();

				String wareHousingReason  = obj.get("wareHousingReason").toString();
