C # Delegate Delegate

Delegate: Store function Reference type

return type and parameter consistency

Using system;using system.collections.generic;using system.linq;using system.text;using System.Threading.Tasks;        Namespace Ch06ex05{class Program {delegate double processdelegate (double param1, double param2);        Static double Multiply (double param1, double param2) {return param1 * PARAM2;        } static double Divide (double param1, double param2) {return param1/param2;            } static void Main (string[] args) {processdelegate process;            Console.WriteLine ("Enter 2 numbers separated with a comma:");            string input = Console.ReadLine (); int commapos = input.            IndexOf (', '); Double param1 = convert.todouble (input.            Substring (0, Commapos)); Double param2 = convert.todouble (input. Substring (Commapos + 1, input.            LENGTH-COMMAPOS-1));            Console.WriteLine ("Enter M to multiply or D to divide:");input = Console.ReadLine ();            if (input = = "M") process = new Processdelegate (Multiply);            else process = new Processdelegate (Divide);            Console.WriteLine ("Result: {0}", Process (param1, param2));        Console.readkey (); }    }}

Why not judge the parameters to pass in and choose different function methods, rather than to delegate it also want to new delegate class ...
