C#对.txt文件的监控处理，解析案例

需要对一个txt文件进行解析

实现后截图 要求：拿到D盘下该文件D:\RhData\result.txt,对其进行解析，文件会发生改变，需要对该文件进行实时监控，每次改变后需要解析保存并记录，后面把这些解析的数据放到一个List《model》里面，供后面需要时使用

实现后截图

我解析文件后首先是放在一个数组里面，然后再存进txt里面。后面list《mode》处理起来挺麻烦的，因为文件格式很不清晰，有些没有对应的数据，比如TITLE_3这种，后面模型的建立就很麻烦。我是自己拿了个解析好的txt文件一个个对数组下标给传值到Model类的。`

这是Program.cs的全部代码,还有一个是Model类`
