C#实现汽车租赁系统项目

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
    
  }
}
