C#基础第四天-作业答案-Hashtable-list<KeyValuePair>泛型实现名片

.Hashtable 实现

Hashtable table = new Hashtable();
            while (true)
            {
                Console.WriteLine("------------------1.增加--------------------");
                Console.WriteLine("------------------2.查询--------------------");
                Console.WriteLine("------------------3.查询全部----------------");
                Console.WriteLine("------------------4.删除--------------------");
                Console.WriteLine("请输入你要使用的功能：");
                int num = int.Parse(Console.ReadLine());
                switch (num)
                {
                    case :
                        Console.WriteLine("请输入姓名：");
                        string name = Console.ReadLine();
                        Console.WriteLine("请输入年龄 性别 爱好 联系方式：");
                        string str = Console.ReadLine();
                        table.Add(name, str);
                        break;
                    case :
                        Console.WriteLine("请输入姓名：");
                        string nameQuery = Console.ReadLine();
                        Console.WriteLine();
                        if (table.Contains(nameQuery))
                        {
                            Console.WriteLine(nameQuery + " " + table[nameQuery]);
                        }
                        break;
                    case :
                        Console.WriteLine();
                        foreach (DictionaryEntry d in table)
                        {
                            Console.WriteLine(d.Key + " " + d.Value);
                        }
                        break;
                    case :
                        Console.WriteLine("请输入姓名：");
                        string delete = Console.ReadLine();
                        table.Remove(delete);

                        break;
                }

:list<KeyValuePair>泛型实现

            List<KeyValuePair<string, string>> listkey = new List<KeyValuePair<string, string>>();
            while (true)
            {
                Console.WriteLine("------------------1.增加--------------------");
                Console.WriteLine("------------------2.查询--------------------");
                Console.WriteLine("------------------3.查询全部----------------");
                Console.WriteLine("------------------4.删除--------------------");
                Console.WriteLine("请输入你要使用的功能：");
                int num = int.Parse(Console.ReadLine());
                switch (num)
                {
                    case :
                        Console.WriteLine("请输入添加的姓名：");
                        string name = Console.ReadLine();
                        Console.WriteLine("请输入年龄 性别 爱好 联系方式：");
                        string str = Console.ReadLine();
                        listkey.Add(new KeyValuePair<string, string>(name, str));
                        Console.WriteLine("成功");
                        break;
                    case :
                        Console.WriteLine("请输入查找的姓名：");
                        string nameQuery = Console.ReadLine();
                        Console.WriteLine();
                        if (listkey)
                        {
                            Console.WriteLine(nameQuery + " " + listkey[nameQuery]);
                        }
                        Console.WriteLine("成功");
                        break;
                    case :
                        Console.WriteLine("查找全部");
                        foreach (DictionaryEntry d in listkey)
                        {
                            Console.WriteLine(d.Key + " " + d.Value);
                        }
                        Console.WriteLine("成功");
                        break;
                    case :
                        Console.WriteLine("请输入删除的姓名：");
                        string delete = Console.ReadLine();
                        table.Remove(delete);
                        Console.WriteLine("成功");
                        break;
