金牌笔试题 原老师版

1. 机试题

 

定义一个班级类，并定义相关的类成员。

public class Grade

要求班级类中包含一个泛型集合，用于存放学生集合。

List<Student> list=new List<Student>();

定义该类中的一个方法（DisplayStudent）：要求：公有的，有一个Point类型的形参，

其功能是能以形参指定的位置为起点，一字排开显示所有的学生对象。

 

书写一个AddStudent（）用于添加学生

需要动态生成控件喔！！！

 

 

代码如下：

 //Grade类

using System;
using System.Collections.Generic;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Exam2
{
   public class Grade
    {
       List<Student> list = new List<Student>();
       public List<string> DisplayStudent(Point point) 
       {
           int count = 0;
           List<string> newList = new List<string>();
           foreach (Student item in list)
           {
               count++;
               newList.Add(item.StuName + ":" + (point.X + 80 * count) + ":" + (point.Y + 50));
           }
           return newList;
       }
       //添加学生
       public void AddStudent(Student stu) 
       {
           list.Add(stu);
       }
    }
}

 //student类

namespace Exam2
{
   public  class Student
    {
        public string StuName { get; set; }//学生姓名
    }
}
