设计一个windows应用程序,输入一个正整数,逆序打印出每一个位数

1、1.设计一个 windows 应用程序，输入一个正整数，逆序打印出每一个位数using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace WindowsFormsApplication1public partial class Form1 : Formpublic Form1()Initi

2、alizeComponent();private void button1_Click(object sender, EventArgs e)textBox1.Text = ;textBox2.Text = ;textBox1.Focus();private void button2_Click(object sender, EventArgs e)int a = int.Parse(textBox1.Text);int b = 0;while (a 0)b = b * 10 + a % 10;a = a / 10;textBox2.Text = b.ToString();2. 设计一个简单的

3、 windows 应用程序，输入联系人的姓名，电话和 email ，单击“添加”按钮，显示联系人的相应信息using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace WindowsFormsApplication1public partial class Form1 : Formpubl

4、ic Form1()InitializeComponent();private void button1_Click(object sender, EventArgs e)string name = textBox1.Text;string phone = textBox2.Text;string email = textBox3.Text;AddressBook ab = new AddressBook(name,phone,email);label4.Text += 姓名： + ab.Name + n + 电话： + ab.Phone + n +Email： + ab.Email + n;

5、private void button2_Click(object sender, EventArgs e)textBox1.Text = ;textBox2.Text = ;textBox3.Text = ;textBox1.Focus();3. 自定义一个时间类。该类包含小时，分，秒字段与属性，具有将秒增加1 秒的方法using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using S

6、ystem.Text;using System.Windows.Forms;namespace WindowsFormsApplication1public partial class Form1 : Formpublic Form1()InitializeComponent();private void button1_Click(object sender, EventArgs e) int hour = int.Parse(textBox1.Text);int minute = int.Parse(textBox2.Text);int second = int.Parse(textBox

7、3.Text);Time t = new Time(hour, minute, second);t.AddSecond();textBox1.Text = t.Hour.ToString();textBox2.Text = t.Minute.ToString();textBox3.Text = t.Second.ToString();private void button2_Click(object sender, EventArgs e)textBox1.Text = ;textBox2.Text = ;textBox3.Text = ;private void Form1_Load(obj

8、ect sender, EventArgs e)Time t = new Time();textBox1.Text = t.Hour.ToString();textBox2.Text = t.Minute.ToString();textBox3.Text = t.Second.ToString();4. 设计一个 windows 应用程序，在该程序中首先构造一个学生基本类，再分别构造小学生，中学生，大学生等派生类，当输入相关数据，单击不同按钮（小学生，中学生，大学生）将分别创建不同的学生对象， 并输入当前的学生总人数， 该学生的姓名， 学生类型和平均成绩using System;using S

9、ystem.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace WindowsFormsApplication1public partial class Form1 : Formpublic Form1()InitializeComponent();private void button1_Click(object sender,

10、 EventArgs e) String name = textBox1.Text;int age = int.Parse( textBox2.Text );double chinese = double.Parse( textBox3.Text );double math = double.Parse( textBox4.Text );Pupil stu = new Pupil(name,age,chinese,math);label6.Text += 总人数： + Student.number + , +姓名： + stu.Name + , +小学生 , 平均成绩为： + stu.Aver

11、age() + n;private void button2_Click(object sender, EventArgs e) String name = textBox1.Text;int age = int.Parse(textBox2.Text);double chinese = double.Parse(textBox3.Text);double math = double.Parse(textBox4.Text);double english = double.Parse(textBox5.Text);Middle stu = new Middle(name, age, chinese, math,english);label6.Text += 总人数： + Student.number + , + 姓名： + stu.Name + , +中学生 , 平均成绩为： + stu.Average() + n;private void button3_Click(object sender, EventArgs e)String name = textBox1.Text;int age = int.Parse(textBox2.Text);double bixiu = double.Parse(textBox3.Text);double xuanxiu =
