今天來介紹一個繼承的範例

public class Car
{
  //Field，我們習慣將變數前面加＿ 表全域變數
  private string _type;
  private string _registration;
  private string _year;

  //constructor
  public Car(string type, string registration, string year)
  {
    _type = type;
    _registration = registration;
    _year = year;
  }

}

public class Toyota: Car
{
  //constructor                                    //實作上層Car的Constructor
  public Toyota(string registration, string year): base("001","Reg1","1998")
  {

  }
            //new出一個物件
  Car Car = new Car();
  //型別轉換
  (Car)Toyota.method();
}
