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

{
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()
{
double rentMoney;
rentMoney = this.RentDate * this.EverydayMoney;
return rentMoney;
}
}
}
汽车
using System;

public Car( string color,double everydaymoney,string no,string name,int rentdate,string load,string rentuser,int services)
:base(color,everydaymoney,no,name ,rentdate,load,rentuser,services)
{
}
//省略重写汽车计算价格方法
}
}
卡车
using System;
