Dictionary with delegate or switch?

Question

I am writing a parser which calls some functions dependent on some value.

I can implement this logic with simple switch like this:

switch(some_val)            


        

Answer 1

I strongly prefer the dictionary choice, because with an initializer, it can be a lot more compact and readable:

var actions = new Dictionary
{
  {1, () => Console.WriteLine("One!")},
  {2, () => Console.WriteLine("Two!")}
}

Also, you have some more flexibility; you can add conditions and actions programatically, which is often handy, depending on what you're doing.
