C#日志记录设计与实现.docx

1、C#日志记录设计与实现C#日志记录设计与实现日志记录：日志记录在程序设计开发过程中，是非常重要的，可以供调试和记录数据，虽然说有开源的强大日志管理系统，比如apache的Log4Net，功能可谓强悍，但是有时候，不需要这么大的日志，只需要显示和文件记录就可以了，没必要用这么重的日志系统，那么就需要自己来写，如下就是一个简单的日志记录和显示模块的设计和实现，如有不足，还望见谅！废话不多，直入主题。笨小孩日志：BenXHLog类文件设计：文件结构简单，类图就不画了，细心的已经发现了，这就是一个简单工厂模式，程序代码：Ilog接口 1 using System; 2 using System.Col
