       {
           Console.WriteLine("Inside BaseClass1 : Method1.");
       }
   }
   
   public class DerivedClass1 : BaseClass1
   {
       public override void Method1()
       {
           Console.WriteLine("Inside DerivedClass1 : Method1.");
       }
   }
   
   public class DerivedClass2 : DerivedClass1
   {
       public override void Method1()
       {
           Console.WriteLine("Inside DerivedClass2 : Method1.");
       }
   }
   
   class Program
   {
       static void Main(string[] args)
       {
           Console.WriteLine("For First case:");
           BaseClass1 baseClass1 = new DerivedClass2();
           baseClass1.Method1();
           
           Console.WriteLine("For Second case:");
           DerivedClass1 baseClass2 = new DerivedClass2();
           baseClass2.Method1();
       }
   }
}

Output

For First case:
Inside DerivedClass2 : Method1.
For Second case:
Inside DerivedClass2 : Method1.
