Given the following C# class definitions and code:

    public class Test
    {
        public void name()
        {
            printName();
        }
        protected virtual void printName()
        {
            Console.WriteLine("name");
        }
    }
    public class Test1 : Test
    {
        protected override void printName()
        {
            Console.WriteLine("name1");
        }
    }
    class Program
    {
        static void Main(string[] args)
        {
            new Test().name();
        }
    }

Output is "name"
But I am excepting output is "name1"
How can I do it?

    Hi Thamotharan-5143,
    You cannot explicitly call the base function from outside the scope of Test or Test1.
    And Sasha Truf has pointed out that you can edit MSIL instead of C# to achieve it.
    More details you can refer to this thread.
    Best Regards,

    If I correctly understand what you want to do the following should meet your objective.

    Test t = new Test();
    t.name(); // Output is "name"
    
    Test tBase = new Test1();
    tBase.name(); // Output is "name1"
