我的任务
分享C#解析指定格式字符串的问题
近来在实际的工作中需要使用到具有某些格式的字符串。例如：
<!--Repeater Id='R1' OderBy='Desc'-->
<!--Repeater End-->
大致是这样的格式：
<!--PropertyName Attribute=AttributeValue-->
Content
<!--PropertyName End-->
我需要取得PropertyName是什么 和Attribute是什么还有Attribute的值。Content的值也需要取，而且Content可能是另外的一个Property
希望朋友们能不吝赐教。

那像动软的模版文件他是怎么去解析的呢，他的<#...#>里面可以直接写C#代码，然后生成类，这方面我还比较陌生，有没有相关的文章可供参考！

要的就是这个解析器实现的方式。[/quote]
首先要知道是哪个CMS,然后是.net的还是php或jsp的,一般都是从生成页面的页面下手去找,看看生成按钮所调用的方法,然后根据方法名称去找代码,

这些应该都是某个CMS的模板代码吧,你没有经过对方的模板解析器,当然不能解析出对应的代码了,与.net 有毛关系啊
