how to call a second-level base class method

Hi all
I'm changing a C++ style code into C#, and naturally facing some problems. in the original C++ code I had 3 classes and a function in all of them, as shown below:

Code:

---

public class A{
public void tick();
}

public class B: A
{
public override void tick();
}

public class C: B
{
public override void tick(){
...
A::tick();  //calling the second-level base class method
}

}

how can I do such a thing?

You're looking at class-level functions instead of object-level functions, so you'd utilize static methods in C#:

Code:

---

    class A
    {
        public static void Tick() { Console.WriteLine("In A."); }
    }

    class B : A
    {
        public new static void Tick() { Console.WriteLine("In B."); }
    }

    class C : B
    {
        public new static void Tick()
        {
            Console.WriteLine("In C.");
            A.Tick();
            B.Tick();
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            C.Tick();
        }
    }

Code:

---

In C.
In A.
In B.
