Is there any advanced compiler-compiler lexer/parser in C#?

Question

I want to know Is there any compiler-compiler library that is written in C# or Not ?

I know Antlr & JavaCC but these library wrote in Java

Is there any library like antlr but in C# (or ported in C#) and open source or not ?

Can anybody introduce them ?

Answer 1

There is Irony. I've never used it myself though.

Answer 2

The C# compiler is itself written in C#, and with Roslyn, this has been made open source.

There is also a C# port of JavaCC, however, it's no longer maintained. The author switched to Irony instead. If you're just looking for code for examples, it would do that.
