Question

What do I need to do to first run the method in the base class then run the same method in the derived class? Is this a good idea?

I want run common actions in base class and extend it in the derived class in the same method. Is this how it is usually done?

public abstract class MyBase
{
  void DoStuff()
  {
    //some common implementation
  }
}

public class MyDerived : MyBase
{
  void DoStuff()
  {
    // DoStuff in the base first
    // Then DoStuff in here
  }
}

Answer 1

are you talking about something like that?

class base
{
  protected virtual void method()
  {
     // do some stuff in base class, something common for all derived classes
  }
}

class derived :  base
{
  public override void method()
  {
    base.method(); // call method from base
    // do here some more work related to this instance of object
  }
}

that’s not a bad idea, I do use it a lot when I have some common functionality for all derived classes.
