异常处理(Exception Handling)是所有系统的最基本的基础操作之一,其它的比如日志(Logging).审核(Auditing).缓存(Caching).事务处理(Transaction)等: 今天,来把异常处理引入到我们在<MVP之V和P的交互>中Calculator的实例中,简单的实现AOP.实例运行如图: 那么,开始我们开简单的介绍下Enterprise Library EHAB(Exception Handling Application Block)提供了一种基于策略(P…

什么是MVP?在“MVP初探”里就有讲过了,就是一种UI的架构模式. 简单的描述一下Unity和Exception Handling Application Block: Unity是一个轻量级的可扩展的依赖注入(DI)容器,支持构造函数,属性和方法调用注入.构建一个成功应用程序的关键是实现非常松散的耦合设计.松散耦合的应用程序更灵活,更易于维护 . 微软Enterprise Library EHAB(Exception Handling Application Block)提供了一种基于策略(…
