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 { public Inheritance() { } public Inheritance(string color,double everydaymoney,string no,string name,int rentdate,string load,string rentuser,int services) { 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;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks; namespace 汽车租赁系统{ public class Car:Inheritance { public Car() { } 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;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks; namespace 汽车租赁系统{ public class Truck:Inheritance { public Truck() { } public Truck( 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) { } //省略重写卡车计算方法 }}

主界面
