一、系統窗體
1)vehic類
//父類 汽車類
public abstract class Vehicle
{
//汽車牌照
public string CarID { get; set; }
//汽車名
public string Name { get; set; }
//顏色
public string Color { get; set; }
//使用 時間
public int RentDate { get; set; }
//日租金
public int Price { get; set; }
//計算租金的抽象方法
public abstract double GetPrice(int day);
}
2）Car小轎車類
//小車類
public class Car:Vehicle
{
//計算汽車租金
public override double GetPrice(int day)
{
double Price = this.Price * day;
return Price;
}
}
3）Truck卡車類
public class Truck:Vehicle
{
//卡車載重
public int Load { get; set; }
//計算卡車的租金
public override double GetPrice( int day)
{
double Price = this.Price * day;
return Price;
}
}
4）FrmMain窗體的代碼
