Explicit Interface Implementation

In the above example function F1( ) of class C3 is providing same implementation to the function F1( )of 11 interface and also the to the function F1 ( ) of 12 interface

But we want to provide different implementations to the function F1 ( ) inherited from 11 interface and to the function F1 ( ) inherited from 12 interface with in the derived class C3. This is known as Explicit Interface Implementation

Example :-

using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace CAInterface2 {     interface I1     {         void F1();     }     interface I2     {         void F1();     }     class C : I1, I2     {         void I1.F1()         {             Console.WriteLine("This is overriding function of I1 Interface");         }         void I2.F1()         {             Console.WriteLine("This is overriding function of I2 Interface");         }     }     class CLSInterface2     {         static void Main(string[] args)         {             C obj1 = new C();             I1 obj2 = (I1)obj1;             I2 obj3 = (I2)obj1;             obj2.F1();             obj3.F1();             Console.ReadLine();         }     } }

Output :-
