本文实例为大家分享了C#实现汽车租赁系统的具体代码，供大家参考，具体内容如下
汽车和卡车的父类

using System.Linq;
using System.Text;
using System.Threading.Tasks;
//父类变量和方法
namespace 汽车租赁系统
{

{
this .Color = color;
this .EverydayMoney = everydaymoney;
this .No = no;
this .Name = name;
this .RentDate = rentdate;
this .Load = load;
this .RentUser = rentuser;
this .Services = services;
}
public string Color { get ; set ; }
public double EverydayMoney { get ; set ; }
public string No { get ; set ; }
public string Name { get ; set ; }
public int RentDate { get ; set ; }
public string Load { get ; set ; }
public string RentUser { get ; set ; }
public int Services { get ; set ; }
//父类计算租金方法
public virtual double Vehicle()
{

}
}
}
汽车

: base (color,everydaymoney,no,name ,rentdate,load,rentuser,services)
{
}
//省略重写汽车计算价格方法
}
}
