Silverlight下的MVVM模式的应用

Application of MVVM Pattern in Silverlight

为了改善传统开发方式和应用RIA(Rich Internet Application,富互联网应用程序)开发技术,文中应用了一种新的设计模式-MVVM,提出了一套基于MVVM模式的系统开发方案。介绍了MVVM模式设计思想,阐述了系统的设计,以实际流程为例,在Silverlight开发环境下给出了具体的实现以及代码比对分析。实践表明,将该模式应用于系统开发,可以成功地将数据、表示和业务逻辑分离,有效地改善系统开发,使系统具有结构清晰、可拓展、易测试的特点。

In order to improve the way of traditional development and apply the RIA development technologies, a new design pattern, MV- VM,is used, a development plan based on it is presented. Introduce the design idea of this pattern, and then give an implementation in Sil- verlight and comparative analysis of the code by using an actual process as example. Practice shows that by using this pattern in the sys- tem development, the data, display and logical transaction can be successfully divided, system can be improved effectively, and has the characteristics of clear structure, stability and ease to be tested.
