C# How to get a list of defined preprocessor?

Question

I know I can check if a preprocessor directive is defined using the #if syntax.

But I want to get a list of defined preprocessor directives to pass it over to a realtime compiling using CSharpCodeProvider

Thanks for advance.

Answer 1

I don't think that is possible. Related.

The compiler itself doesn't know about preprocessor. It receives already preprocessed code so there is no reason to remember what directives were defined.
