Question

I’m trying to write something that calls a function at runtime without using reflection.

Below is my attempt that doesn’t work D:

 public delegate void FunctionPointer(string t);

 public void UseFunctionPointer(string t)
    {
        FunctionPointer pointer = t;
        t();
    }

I realize I can use a giant switch or if/else to match them, but I want to keep the code clean.

can someone point me to the right direction?
or tell me “it is impossible”

Answer 1

Dictionary of functions by name could be an option:

var functions = new Dictionary<string, Func<float, float>>();
functions.Add("sqr", x=>x*x);

Console.WriteLine(functions["sqr"](3));
