What you're looking for is an abstract syntax tree parser for Javascript written in C#.

There are a few choices I know of:

Microsoft's Ajax Minifier library comes with its own AST parser (used to minify / optimize Javascript files). You can find the source code for that on Codeplex.

Esprima.net is another option. It's a port of the popular Javascript library Esprima.

The good thing about Esprima is it outputs the AST in a common format (defined by Mozilla here) that's used across a few parsers, making it really easy to port utilities for walking the tree, etc. since they all use the same underlying data structure.
