Is there a library for .NET that does parenthesis or expression reduction and optimization?

Is there a library for .NET that does parenthesis or expression reduction and o开发者_JAVA技巧ptimization? Something that would take an expression such as (A & (((B) | (C)) | D))) and return

A & (B | C | D)

But also take (A & A) and return A

This is more in the domain of a standalone parser/lexical analyzer. But ANTLR has a rather nice C# binding, if that would suit your purposes.

It probably wouldn't be very much work to write a simple parser for strings of this sort and do the reduction yourself.

I'm not a LINQ expert, but if you wanna get your hands dirty, the datastructures for such a task already exist in .Net Expression Trees:

You'd still have to parse the string to create the tree though.
