virtual properties

Question

I have used and learned only virtual methods of the base class without any knowledge of virtual properties used as

class A
{
   public virtual ICollection<         


        

Answer 1

public virtual ICollection Prop { get; set; }

Translates almost directly to:

private ICollection m_Prop;

public virtual ICollection get_Prop()
{
    return m_Prop;
}

public virtual void set_Prop(ICollection value)
{
    m_Prop = value;
}

Thus, the virtual keyword allows you to override the property in sub-classes just as you would the above get/set methods:

public override ICollection Prop
{
    get { return null; }
    set { }
}
