Answer 1

Reflection targets assembly, class and interface structure. It gives access to class definitions, method signatures, type information, and so on. It doesn't provide access the code of methods, either in Abstract Syntax Tree (AST) or bytecode form.

The Expression<> type family provides direct access to an AST, which can be used to glean the structure of a piece of code. This is actually much closer to the CodeDOM facility than to reflection.
