Answer 1

You can use base to fill values in the constructor of an object's base class.

Example:

public class Class1
{
    public int ID { get; set; }
    public string Name { get; set; }
    public DateTime Birthday { get; set; }

    public Class1(int id, string name, DateTime birthday)
    {
        ID = id;
        Name = name;
        Birthday = birthday;
    }
}

public class Class2 : Class1
{
    public string Building { get; set; }
    public int SpotNumber { get; set; }
    public Class2(string building, int spotNumber, int id, 
        string name, DateTime birthday) : base(id, name, birthday)
    {
        Building = building;
        SpotNumber = spotNumber;
    }
}

public class Class3
{
    public Class3()
    {
        Class2 c = new Class2("Main", 2, 1090, "Mike Jones", DateTime.Today);
    }
}
