工厂方法模式实现数据绑定控件的初始化数据加载框架

The Factory Method Pattern is Used to Initialize the Data Loading Frame of Data Binding Control

基于.Net的软件项目开发中集合控件频繁被使用,用于展示数据信息并提供用户信息选择[1].每一个集合控件都具有各自的特性,在程序运行时对每个集合控件进行信息的填充,而大量集合控件的数据信息添加工作需要重复自定义方法调用,因此势必造成代码的冗余和程序源码可读性下降.充分利用OOP(面向对象编程)结合工厂方法模式,把每个集合控件数据加载交给专门的工厂类实现,并抽象出各个集合控件的共性放在抽象产品类中,最终形成一个采用工厂方法模式的框架应用到软件开发项目中.

Net based software project development in the collection control is frequently used, such as List- Box, ListView, ComBox and other data for the display of information and provide users with information to choose. Each set of control has its own characteristics, each collection control fills information when the program runs. The work of adding a large number of data information of collections control need to repeat the custom method calls, it is bound to cause the redundancy of the code and readability decline of program source. In view of the above, making full use of OOP （object oriented programming）combined with the fac- tory method pattern,each set of control data is loading by specialized factory implementation,and the uni- versality of each collections control is abstracted to put in the abstract product category, eventually the fac- tory methold pattern framework is applied to a software development project.
