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<ProductFather> list = new List<ProductFather>();//存储货物//list接收的是List<>,相当于货架List<List<ProductFather>> list = new List<List<ProductFather>>();/// <summary>/// 向用户展示货物/// </summary>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/// <summary>/// 在创建仓库对象的时候，向仓库中添加货架/// </summary>public CangKu(){list.Add(new List<ProductFather>());list.Add(new List<ProductFather>());list.Add(new List<ProductFather>());list.Add(new List<ProductFather>());}/// <summary>/// 进货/// </summary>/// <param name="strType">货物的类型</param>/// <param name="count">货物的数量</param>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;}}}/// <summary>/// 取货/// </summary>/// <param name="strType">货物的类型</param>/// <param name="count">数量</param>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;}}
