How to call base abstract class virtual method ?

namespace ExcelCopy

{

public class Program : Abs

{

static void Main(string[] args)

{

Program p = new Program();

p.NonAbstract();

Abs a = new Program();

a.NonAbstract();

}

public override void GetFullName()

{

throw new NotImplementedException();

}

public override void NonAbstract()

{

Console.WriteLine("I am method five from child class, I have my own implimentation");

}

public abstract class Abs

{

public abstract void GetFullName();

public virtual void NonAbstract()

{

Console.WriteLine("Hi i ma non abstract method from abstract class");

Thank you Anil for your reply.
I just wanted to check that is there anyway to invoke virtual method without using new keyword?

Ajit,

If you override virtual method in child class then you wouldn't have parent class implementation. If you want to do so then use new keyword instead.
Here is the implementation that you can call parent class method.
namespace AbstractClass
{
    public class Program : Abs
    {
        static void Main(string[] args)
        {
            Program p = new Program();
            p.NonAbstract();
            Abs a = new Program();
            a.NonAbstract();

            Console.ReadLine();
        }
        public override void GetFullName()
        {
            throw new NotImplementedException();
        }
        public new void NonAbstract()
        {
            Console.WriteLine("I am method five from child class, I have my own implimentation");
        }
    }
    public abstract class Abs
    {
        public abstract void GetFullName();
        public void NonAbstract()
        {
            Console.WriteLine("Hi i ma non abstract method from abstract class");
        }
    }
}
Output:
