Parser for the Mathematica syntax?

Question

Is there a built parser that I can use from C# that can parse mathematica expressions?

I know that I can use the Kernel itself to parse an expression, and use .NET/Link

Answer 1

My matheclipse-parser module implements a parser in Java which can parse a big subset of mathematica expressions. See the readme.md page for usage. Maybe you can port the parser to C#?
