Using a baseclass method return value?

Question

I have a method in my baseclass that returns a bool and I want that bool to determine what happens to the same overridden method in my derived class.

Base:

    public bool Debt(double bal)
    {
        double deb = 0;
        bool worked;

        if (deb > bal)
        {
            Console.WriteLine("Debit amount exceeds the account balance – withdraw cancelled");
            worked = false;
        }
        else

        bal = bal - deb;
        worked = true;

        return worked;
    }

Derived

public override void Debt(double bal)
    {
        // if worked is true do something

    }

Note that bal comes from a constructor I made earlier

Answer 1

You can call the base class method using the base keyword:

public override void Debt(double bal)
{
    if(base.Debt(bal))
        DoSomething();

}

As indicated in the comments above, you either need to make sure that there is a virtual method with the same signature (return type and parameters) in the base class or remove the override keyword from the deriving class.

Answer 2

if(base.Debt(bal)){
    // do A
}else{
    // do B
}

base refers to the base class. So base.X refers to X in the base class.

Answer 3

Call the base method:

public override void Debt(double bal)
{
    var worked = base.Debt(bal);
    //Do your stuff
}
