I see two reasons your original set of declarations shouldn’t compile cleanly: There should be a warning in TCellPhone that its constructor hides the method of the base class. This is because the base-class method is virtual, and the compiler worries that you’re introducing a new method with the same name without overriding the base-class … Read more
No, there is no way to do this. According to the language specs, instance variables aren’t even initialized until a super() call has been made. These are the steps performed during the constructor step of class instance creation, taken from the link: Assign the arguments for the constructor to newly created parameter variables for this … Read more
If I remember correctly, then reintroduce should help for virtual methods. The reintroduce directive suppresses compiler warnings about hiding previously declared virtual methods. Use reintroduce when you want to hide an inherited virtual method with a new one. To answer your updated question – I think it’s not possbile to hide a non-virtual constructor with … Read more
The order is: Member variables are initialized to default values for all classes in the hierarchy Then starting with the most derived class: Variable initializers are executed for the most-derived type Constructor chaining works out which base class constructor is going to be called The base class is initialized (recurse all of this 🙂 The … Read more
You use standard syntax (using this like a method) to pick the overload, inside the class: class Foo { private int id; private string name; public Foo() : this(0, “”) { } public Foo(int id, string name) { this.id = id; this.name = name; } public Foo(int id) : this(id, “”) { } public Foo(string … Read more
