I know it's not possible to inherit constructors in C#, but there's probably a way to do what I want to do.
I have a base class that is inherited by many other classes, and it has an Init
method that does some initializing taking 1 parameter. All other inheriting classes also need this initializing, but I'd need to create separate constructors for all of them that would like like this:
public Constructor(Parameter p) {
base.Init(p);
}
That totally violates the DRY principles! How can I have all necessary stuff initialized without creating dozens of constructors?
You don't need to create loads of constructors, all with the same code; you create only one, but have the derived classes call the base constructor:
public class Base
{
public Base(Parameter p)
{
Init(p)
}
void Init(Parameter p)
{
// common initialisation code
}
}
public class Derived : Base
{
public Derived(Parameter p) : base(p)
{
}
}
