GUID：

　　产生一个不会重复的ID

static void Main(string[] args)        {            //产生一个不会重复的编号            Console.WriteLine(Guid.NewGuid().ToString());            Console.WriteLine(Guid.NewGuid().ToString());            Console.WriteLine(Guid.NewGuid().ToString());            Console.WriteLine(Guid.NewGuid().ToString());            Console.WriteLine(Guid.NewGuid().ToString());            Console.ReadKey();        }

分析：

父类：全用的是自动属性

public class ProductFather    {        public double Price        {            get;            set;        }        public string Name        {            get;            set;        }        public double Count        {            get;            set;        }        public string ID        {            get;            set;        }        public ProductFather(string id, double price, double count,string name)        {            this.ID = id;            this.Price = price;            this.Count = count;            this.Name = name;        }    }

子类：Acer

class Acer : ProductFather    {        public Acer(string id, double price, double count, string name)            : base(id, price, count, name)        {        }    }

子类：SumSung

class Acer : ProductFather    {        public Acer(string id, double price, double count, string name)            : base(id, price, count, name)        {        }    }

子类：JiangYou

class JiangYou : ProductFather    {        public JiangYou(string id, double price, double count, string name)            : base(id, price, count, name)        {        }    }

子类：Banana

class Banana : ProductFather    {        public Banana(string id, double price, double count, string name)            : base(id, price, count, name)        {        }    }

仓库类：

class CangKu    {        //List
     
       list = new List
      
       ();        //存储货物        //list接收的是List<>,相当于货架        List
       
        
         > list = new List
         
          
           >(); /// 
            /// 向用户展示货物 /// 
 public void ShowPros() { foreach (var item in list) { Console.WriteLine("仓库现有：" + item[0].Name + "," + "\t" + item.Count + "个," + "\t" + "每个" + item[0].Price + "元。"); } } //list[0]存储Acer电脑 list[1]存储三星手机 list[2]存储酱油 list[3]存储香蕉 /// 
            /// 在创建仓库对象的时候，向仓库中添加货架 /// 
 public CangKu() { list.Add(new List
           
            ()); list.Add(new List
            
             ()); list.Add(new List
             
              ()); list.Add(new List
              
               ()); } /// 
                /// 进货 /// 
 /// 
               货物的类型 /// 
               货物的数量 public void JinPros(string strType, int count) { for (int i = 0; i < count; i++) { switch (strType) { case "Acer": list[0].Add(new Acer(Guid.NewGuid().ToString(), 1000, 100,"宏基笔记本电脑")); break; case "SamSung": list[1].Add(new SamSung(Guid.NewGuid().ToString(), 2000, 300,"三星手机")); break; case "JiangYou": list[2].Add(new JiangYou(Guid.NewGuid().ToString(), 10, 3000,"老抽")); break; case "Banana": list[3].Add(new Banana(Guid.NewGuid().ToString(), 12, 1000,"香蕉")); break; } } } /// 
                /// 取货 /// 
 /// 
               货物的类型 /// 
               数量 public ProductFather[] QuPros(string strType, int count) { ProductFather[] pros = new ProductFather[count]; for (int i = 0; i < count; i++) { switch (strType) { case "Acer": //判断如果货物数量为0，提示缺货 if (list[0].Count == 0) { Console.WriteLine("缺货"); } else { pros[i] = list[0][0]; list[0].RemoveAt(0); } break; case "SamSung": if (list[1].Count == 0) { Console.WriteLine("缺货"); } else { pros[i] = list[1][0]; list[1].RemoveAt(0); } break; case "JiangYou": if (list[2].Count == 0) { Console.WriteLine("缺货"); } else { pros[i] = list[2][0]; list[2].RemoveAt(0); } break; case "Banana": if (list[3].Count == 0) { Console.WriteLine("缺货"); } else { pros[i] = list[3][0]; list[3].RemoveAt(0); } break; } } return pros; } }
