Is there a way to have a C# class handle its own null reference exceptions

Question

Question

I\'d like to have a class that is able to handle a null reference of itself. How can I do this? Extension methods are the only way I can think

Answer 1

You can't reference a property if you do not have a valid instance reference. If you want to be able to reference a property even with a null reference and not put the onus of null-checking on the caller, one way is a static method in User:

static bool IsAuthorized(User user)
{
    if(user!=null)
    {
        return user.IsAuthorized;
    }
    else
    {
        return false;
    }
}

Then, when you want to check your authorization, instead of:

if(thisUser.IsAuthorized)

Do:

if(User.IsAuthorized(thisUser))
