CSharp – Static Polymorphism – Function Overloading

CSharp – Static Polymorphism – Function Overloading

Polymorphism is a Greek word that means “many-shaped”
With Function Overloading you can have multiple definitions for the same function name in the same scope.
Same name for the function, many-shaped variables.

using System;

namespace ConsoleApplication1
{

    class Printdata
    {
        void print(int i)
        {
            Console.WriteLine("Printing int: {0}", i);
        }

        void print(double f)
        {
            Console.WriteLine("Printing float: {0}", f);
        }

        void print(string s)
        {
            Console.WriteLine("Printing string: {0}", s);
        }
        static void Main(string[] args)
        {
            Printdata p = new Printdata();
            // Call print to print integer
            p.print(5);
            // Call print to print float
            p.print(500.263);
            // Call print to print string
            p.print("Hello C++");
            Console.ReadKey();
        }
    }

}

The result is:

Printing int: 5
Printing float: 500.263
Printing string: Hello C++

For italian people: come funziona?
C# distingue automaticamente la funzione chiamata in base alle variabili che gli vengono spedite, quindi:
p.print(5); -> void print(int i)
p.print(500.263); -> void print(double f)
p.print(“Hello C++”); -> void print(string s)
