Referencing a function in a variable?

Question

Say I have a function. I wish to add a reference to this function in a variable.

So I could call the function 'foo(bool foobar)' from a variable 'bar', as if it was a function. EG. 'bar(foobar)'.

How?

Answer 1

It sounds like you want to save a Func to a variable for later use. Take a look at the examples here:

using System;

public class GenericFunc
{
   public static void Main()
   {
      // Instantiate delegate to reference UppercaseString method
      Func<string, string> convertMethod = UppercaseString;
      string name = "Dakota";
      // Use delegate instance to call UppercaseString method
      Console.WriteLine(convertMethod(name));
   }

   private static string UppercaseString(string inputString)
   {
      return inputString.ToUpper();
   }
}

See how the method UppercaseString is saved to a variable called convertMethod which can then later be called: convertMethod(name).

Answer 2

Using delegates

    void Foo(bool foobar)
    {
/* method implementation */
    }

using Action delegate

Public Action<bool> Bar;
Bar = Foo;

Call the function;

bool foobar = true;
Bar(foobar);

Are you looking for Delegates?
