Question

Suppose I have

class A
{

 public List<B> LiProperty
 {
    get;
    set { //will I get called when someone calls A::LiProperty.Add()? }
 }

}

Then

A a = new A();
a.LiProperty.Add(new B());

Will the mutator ever be called?

My instincts say that get is returning a pointer to the list so the add method is being called directly on the object, but then again C# does some funky stuff sometimes with immutable types. Anybody know the answer for certain?

Answer 1

Changing the property is to change it to point to another different List<T>. Adding an object to the list is not changing which List<T> the property points to. The code will not call the setter unless you wrote a.LiProperty = new List<T>();
