Interface in c#
In this article, we will learn about Interface in c#.
Introduction
Multiple inheritance is a feature in that a class can inherit more than one class. Multiple inheritance can not be implemented in C#. It can only implemented with interfaces.
Important points about interface
- Interface has no implementation. it has only signature.
- All interfaces are by default public and abstract.
- All Interface member also are public and can not have any access specifier.
- Interface instance can not be created.
- Interface can inherit other interface.
- Class can inherit multiple interfaces.
Example
using System;
namespace Dotnetheaven
{
interface Icar
{
int car();
}
interface IPlane
{
bool developer
{
get;
}
}
class sharad : Icar, IPlane
{
public int car()
{
return 4;
}
public bool developer
{
get
{
return true;
}
}
}
class Program
{
static void Main(string[] args)
{
sharad mysupercar = new sharad();
Console.WriteLine(" sharad have " + mysupercar.car() + (" car ") + " He is a Engineer " + mysupercar.developer);
Console.ReadLine();
}
}
}
