I have following class as

C#

public abstract class BaseClass
   {
       public virtual void VirtualMethod()
       {
           Console.WriteLine("NewBaseClass:VirtualMethod");
       }
   }

   public class DerivedClass : BaseClass
   {
       public override void VirtualMethod()
       {
           Console.WriteLine("NewClassA:VirtualMethod");

       }
   }

Now i want to call base class method by creating object of DerivedClass using base keyword

In your example (C++):

C++

// Create an instance of DerivedClass
DerivedClass *dc = new DerivedClass();

// BTW this will work as well:
//BaseClass *dc = new DerivedClass();

// Call the method of base class
dc->BaseClass::VirtualMethod();

// Let' clean
delete dc;

This example shall give an output like:

>NewBaseClass:VirtualMethod

I'm too old to have a motto - perhaps "Too old to die young" if any ;)
