一款国外开发的创建自己语法的解析器
可以根据自己定义的规则解析出相应的C#和VB.NET代码
One of the more difficult tasks in computer science is building parsers and

compilers. There are a lot of tools available that aid in the tedious task, most

notably, Flex and Yacc, both available on the Linux/UNIX platform. The program I

present here in this article is called TokenIcer. It is similar to Flex, but

TokenIcer provides a nice easy to use GUI that serves as an editor for your

rules, as well as a test bed for testing your rules. In addition, once your

parsing rules have been defined, TokenIcer can create a parser class, based on

your rules, in either C# or VB.NET
