Implementing two methods with same name from two different interfaces

If we have to implement a method of same name in two different interfaces,then we need to do it in slight different way:

interface I2
    {
        void print();
    }

 interface I1
    {
        void print();
    }
}


Implementation in a class:
void I1.print()
        {
            Console.WriteLine("This is print method of Interface I1");
        }

         void I2.print()
        {
            Console.WriteLine("This is print method of Interface I2");
        }


And call it like

 ClassChild obj = new ClassChild();
            I1 objI1 = (I1)obj;
            objI1.print();
            I2 objI2 = (I2)obj;
            objI2.print();
