Confusion in Multiple Inheritance using Interface.

Hello @Jigar your method of calling display() method is known as "implicit Interface Implementation"  because we can not decide that  Display() method belong to which class.

It is compiler dependent .  

In  "implicit Interface Implementation"  we can only call interface method using Class instance  not

through Interface Instance ..........

To answer your question, the method implemented in the class will be called, of course, because you do not have a definition in the base entity. Its an interface. You do not get a compilation error because you satisfy the implementation requirement for both interfaces.

 

Now the actual question - What if you have 2 different implementations and wanted to call them individually. You can do so by casting the MyClass object to respective interfaces and then calling Display method. See reference code below:

 

Hello @jigar in your code you can not distinguish that   which display method will be call.

 

because method name of both interface are same .

if yo want to distinguished b/w both display method then you should use Explicit Interface Implementation

 

static void Main(string[] args)
{
MyClass myClass = new MyClass() ;
IOne Itr = myClass;
ITwo Itn = myClass;
Itr.Display();
Itn.Display();
Console.ReadLine();
}


public interface IOne
{
void Display();
}

public interface ITwo
{
void Display();
}
public class MyClass : IOne, ITwo
{
void IOne.Display()
{
Console.WriteLine("test of IOne");
}

void ITwo.Display()
{
Console.WriteLine("test Of Itwo");
}
}
 

 

This name mechanism is also known as a fully qualified name. 

 

If you have any doubt this Please ask...........
