Override get, but not set

Question

I have an abstract class that defines a get, but not set, because as far as that abstract class is concerned, it needs only a get.

public abstract BaseClass {   public abstract double MyPop   {get;} } 

However, in some of the derive class, I need a set property, so I am looking at this implementation

public class DClass: BaseClass {   public override double MyPop   {get;set;} } 

The problem is, I got a compilation error, saying that

*.set: cannot override because *. does not have an overridable set accessor.

Even though I think that the above syntax is perfectly legitimate.

Any idea on this? Workaround, or why this is so?

Edit: The only approach I can think of is to put both get and set as in the abstract class, and let the subclass throws a NotImplementedException if set is called and it's not necessary. That's something I don't like, along with a special setter method .

Answer 1

One possible answer would be to override the getter, and then to implement a separate setter method. If you don't want the property setter to be defined in the base, you don't have many other options.

public override double MyPop {     get { return _myPop; } }  public void SetMyPop(double value) {     _myPop = value; }
