Inheriting and Method using with Multiple Interfaces in C#

The multiple inheritance can be implemented in C# by using the interfaces only. You can inherit a class from multiple interfaces but can inherit a class with only one class.

The below program inherit a class from two interfaces Laptop and PersonalComputer. Both the interfaces have a print method. The main function create an object of each interface and call the corresponding method.

While if we create a object of drive class then the both methods are accessible.

using System;

namespace CSharpInterview
{
    interface PersonalComputer
    {
        void PCPrint();
    }

    interface Laptop
    {
        void LaptopPrint();
    }

    class Computer : Laptop, PersonalComputer
    {
        public void PCPrint()
        {
            Console.WriteLine("PC Print Method.");
        }

        public void LaptopPrint()
        {
            Console.WriteLine("Laptop Print Method.");
        }
    }

    class Programs
    {       
        static void Main(string[] args)
            {

                Laptop ObjLaptop = new Computer();
                ObjLaptop.LaptopPrint();

                PersonalComputer ObjPersonalComputer = new Computer();
                ObjPersonalComputer.PCPrint();

                Console.WriteLine("Computer Class...");
                Computer ObjComputer = new Computer();
                ObjComputer.LaptopPrint();
                ObjComputer.PCPrint();

                Console.ReadLine();
            }
    }   
}
