Partially Overriding a Virtual Auto-Property in a Child Class

Question

Time for a theoretical question I just ran across.

The following code is valid and compiles:

public class Parent
{
    public virtual object TestProperty         


        

Answer 1

This behavior is consistent with non-auto-implemented properties in C#. It's always been possible to override only a get or set method for a virtual property. Hence making it impossible to do with an auto-implemented property would create an unnecessary inconsistency.

For example, the following is legal

class A
{
    public virtual int P1
    {
        get { return 42; }
        set { }
    }
}

class B : A
{
    public override int P1
    {
        get { return 18; }
    }
}
