Console.ReadKey()的用法

Console.ReadLine(); 会等待直到用户按下回车，一次读入一行
Console.ReadKey(); 则是等待用户按下任意键，一次读入一个字符。

class Program
    {
       private List<Student> allStu = newList<Student>();
       string yesORno;
       bool flag = true;
       
       public void AddStudent()
       {
           while (flag)
           {
               Student s = new Student();
               Console.WriteLine("请输入学生姓名:");
               s.StuName = Console.ReadLine();
               Console.WriteLine("请输入学生学号");
               s.StuNum = Console.ReadLine();
               allStu.Add(s);

               

               Console.WriteLine("是否继续输入:请输入y或者n");
               yesORno =Console.ReadKey().Key.ToString();
               
               switch (yesORno)
               {
                   case "Y":
                       flag = true;
                       break;
                   case "N":
                       flag = false;
                       break;
               }
           }
       }

       public void ShowStu()
       {
           for (int i = 0; i < allStu.Count; i++)
           {
               Console.WriteLine(allStu[i].ToString());
           }
       }

       static void Main(string[] args)
       {
           Program p = new Program();
           p.AddStudent();
           p.ShowStu();
           Console.ReadLine();
       }
    }

 

class Student
    {
       private string stuName;

       public string StuName
       {
           get { return stuName; }
           set { stuName = value; }
       }

       private string stuNum;

       public string StuNum
       {
           get { return stuNum; }
           set { stuNum = value; }
       }

       public override string ToString()
       {
           return "姓名" + stuName + "......." + "学号" + stuNum;
       }
    }
