Set a field value in a base class that can be overridden in child classes in C#

Question

I have a C# class that looks like this:

public class Animal { public string _name = "Animal"; public string GetGreeting() { if (this._name == "Animal") { return "Hello friend!"; } else { return $"Hello, '{this._name}'"; } } } public class Tiger : Animal { // How do I set "_name" here? }

I want to hard-code the _name value in the Tiger class. However, I don't want to force other classes to set the _name value. How do I do that in C#?

note: public fields are usually a very bad idea - IMO public string Name {get;set;} would be a far better idea — Marc Gravell

Your hierarchy is pretty strange IMHO. What should new Animal() return? I suppose the base-class shouldn't be instantiable. Better make it abstract. — MakePeaceGreatAgain

Just add a constructor:

public Tiger() { _name = "Tony"; // they're great! }
