How to use my language from c#?

Question

C++ / C#

I wrote my interpreter for my language in C#. Basically, it's a parser. The code is simply stored in a text document. Now I have a task to call a method from my language in c#. In my language, I have a function that will return for example a number multiplied by 2. How to call this function and get the result from it from c#? I don't understand how it can be done

Answer 1

There is a book, "Expressive Javascript", I think. It describes how to make your own interpreter, but. This is for javascript. I don't know how to do this in c#.

Answer 2

Roslyn allows you to work with C# code at runtime, compile assemblies, include them and call them dynamically without any problems, do you need your own language?
