use (this as GrandParent) in the Child's call. i.e., change the Child's
WhoAmI function to
public override void WhoAmI()
{
(this as GrandParent).WhoAmI();
Console.WriteLine("I am Child");
}
What you are doing is not a good programming practice (as the compiler will
tell you with its warnings).
1.cs(27,21): warning CS0114: 'Parent.WhoAmI()' hides inherited member
'GrandParent.WhoAmI()'. To make the current member override that
implementation, add the override keyword. Otherwise add the new
keyword.
1.cs(16,21): (Location of symbol related to previous warning)
1.cs(38,21): warning CS0114: 'Child.WhoAmI()' hides inherited member
'Parent.WhoAmI()'. To make the current member override that
implementation, add the override keyword. Otherwise add the new
keyword.

You should override inherited virtual functions if you are implementing new
functionality.
