Is Interface used for implementing multiple inheritance since multiple inheritance is not possible with class?

Santhosh Kumar Jayaraman · Answer

Generally if you use classes your child class can inherit only from one parent class. Multiple inheritances are not allowed in c#. but with interfaces you can inherit a child class from multiple interfaces. Also it provides uniformity and standardization of methods. Check this for real time example. http://www.shubho.net/2010/08/what-is-interface-why-should-you-use.html

Wanted to know the purpose of using Interface

Santhosh Kumar Jayaraman · Answer

Abstract class can have one more implemented methods. But interface should have only non implemented methods public abstract class myclass { void getNames(); void Getdetails() { //do something; } public interface IVehicle { void getNames(); void Getdetails(); } One more is you can provide access specifier for the methods in abstract class but you cant specify any for interface methods not even public.
