I am going to guess that what you are after is something like this: using a Dictionary whose Key is an Enum value, and whose Value is executable code defined in a deferred form (Func, Action, Delegate, Lambda Expression):
using System;
using System.Collections.Generic;

namespace YourNameSpace
{
    public enum Fruit
    {
        NoFruit, Apple, Orange
    }

    public class FruitCalc
    {
        private Dictionary<Fruit, Func<int, int, Fruit>> CalcFruitDict
            = new Dictionary<Fruit, Func<int, int, Fruit>>
            {
                // lambda notation used here
                {Fruit.Apple, (int napples, int noranges) => napples > noranges ? Fruit.Apple : Fruit.NoFruit },
                {Fruit.Orange, (int napples, int noranges) => napples < noranges ? Fruit.Orange : Fruit.NoFruit },
            };

        public Fruit Calculate(Fruit fruit, int napples, int noranges)
        {
            if (fruit == Fruit.NoFruit)
            {
                throw new InvalidOperationException("Sorry, no fruit means no fruit");
            }

            // check integer parameters for valid range ?

            return CalcFruitDict[fruit](napples, noranges);
        }
    }
}
Usage example:
FruitCalc fcalc = new FruitCalc();

Fruit f1 = fcalc.Calculate(Fruit.Apple, 12, 4);
Fruit f2 = fcalc.Calculate(Fruit.Orange, 14, 24);

Fruit f3 = fcalc.Calculate(Fruit.Apple, 2, 4);
Fruit f4 = fcalc.Calculate(Fruit.Orange, 14, 2);

// force an error
Fruit f5 = fcalc.Calculate(Fruit.NoFruit, 12, 4);
Note: the case where number of apples equals number of oranges is not handled here.
