How do I call the constructor of a parent class?

If I have something like

abstract class parent {
  public parent(string mom, string dad) {...}
}

public class child : parent {
  //how do I cal the constructor of parent?
}

abstract class parent {
  public parent(string mom, string dad) {...}
}

public class child : parent {
  //how do I cal the constructor of parent?
}

All of the tutorials i've found only talk about inheriting a class.

abstract class Parent
{
  public Parent(string mom, string dad)
  {
    ...
  }
}

public class Child : Parent
{
  public Child(string mom, string dad)
    : base(mom, dad)
  {
    ...
  }
}

abstract class Parent
{
  public Parent(string mom, string dad)
  {
    ...
  }
}

public class Child : Parent
{
  public Child(string mom, string dad)
    : base(mom, dad)
  {
    ...
  }
}

Public child() : base(“mom”, “dad”)

so base works as the parent class's constructor?

this seems like a weird thing to represent with inheritance

base call the parent constructor

Aaron•2y ago

yes

AvisOP•2y ago

thank you!

As the parent in general. You can use ‘base.ParentMethod()’ for e.g. just check the docs on keyword

quick question wouldn't this make a second child class inside the first?

vdvman1•2y ago

What makes you say that?

so Parent Child Child

nop unless you have static

AvisOP•2y ago

public class Child : Parent // make a child class
{
  public Child(string mom, string dad)
    : base(mom, dad) //oh wait this is the constrctor for Child?

  {
    ...
  }
}

public class Child : Parent // make a child class
{
  public Child(string mom, string dad)
    : base(mom, dad) //oh wait this is the constrctor for Child?

  {
    ...
  }
}
