Question

I do not get the following..I always thought I can access private fields only from class which the field was declared in. However in this case I am able to access it:

class Session
{
    List<client> ListOfClients = new List<client>();

    public void IterateClients(Action<client> action)
    {

    }
}

class client
{
    private int A;

    Session area;

    public void SendData()
    {
        area.IterateClients(delegate(client c)
        {
            c.A = 5; //how come this is accessible?
        });
    }
}

Answer 1

Technically it’s not Session class that’s accessing private A variable, it’s delegate function created in SendData() that does this. There is no problem with that. Think of it as IterateClients is just calling method from client class, which method can access A variable since it is on the same class.
