Identify which Foo method will be called.

Manish Singh

Hi..........

Ques : My problem is Without running this code, identify which Foo method will be called:

Code :

class A
{
   public void Foo( int n )
   {
      Console.WriteLine( "A::Foo" );
   }
}

class B : A
{
   /* note that A::Foo and B::Foo are not related at all */
   public void Foo( double n )
   {
      Console.WriteLine( "B::Foo" );
   }
}

static void Main( string[] args )
{
   B b = new B();
   /* which Foo is chosen? */
   b.Foo( 5 );
}

Which method? And why?

Hello dear manish

i have understand your question here and the output will be
Console.WriteLine( "B::Foo");

Because it will cast automatictly and use the first without going further in the inheritance.

class B : A
{
/* note that A::Foo and B::Foo are not related at all */
public void Foo( double n )
{
Console.WriteLine( "B::Foo" );
}
}

the above class will be called bcoz of this line
B b = new B();
