Default Searching an expression in a text file.

I am facing problem of matching an expression in a text file using C# in ASP.NET. The expression used will look like: ((apple AND orange) OR (car OR lorry)). A text file will be use to search for those keyword matching with the expression given. Do any one has any idea of how to perform the matching for expression mentioned above?

Rachellim,

On the surface, this doesn't appear to be too difficult a task. In general, I use regular expressions for matching operations. Regular expressions are quite powerful. Because they are so powerful, they are also somewhat complex. You might start by checking out the following link:

If you have further, specific questions, I'll be happy to assist.

Cheers.
