C# Visual Studio 2008实验报告附源代码using System; usingSystem.Collections.Generic;using System.Linq;using System.Text; 1、创建C#控制台应用程序。设计一个简单的密码验证程序，若密码正确，则显示“欢迎进入本系统！”，否则显示“密码输入错误，请重新输入！”。若连续三次密码输入错误，则显示“对不起，超过最多输入次数，取消服务！”，程序退出。namespace ConsoleApplication1class Program static void Main(string args) int i = 0; string mima = 123321; bool k = true; Console.WriteLine( ); Console.WriteLine( 欢迎使用本系统nn); Console.WriteLine( 请输入您的服务密码： ); while (k) string get = Console.ReadLine(); if (get != mima) i+; if (i = 3) Console.WriteLine(对不起，输入的密码错误次数超过三次，nn已取消服务，请按任意键结束！ ！); Console.ReadLine(); break; else Console.WriteLine(对不起，密码有误，已经输入0次，请重新输入 ！,i ); else Console.WriteLine(欢迎进入本系统！); Console.ReadLine(); break; using System;using System.Collections.Generic;using System.Linq;using System.Text;4定义一个shape抽象类，利用它作为基类派生出Rectangle、Circle等具体形状类，已知具体形状类均具有两个方法GetArea和GetPerim，分别用来求形状的面积和周长。最后编写一个测试程序对产生的类的功能进行验证。namespace shiyan14 public abstract class Shape public double GetArea() return 0; public double GetPerim() return 0; public class Circle:Shape private double r; public Circle(double a) r=a; public new double GetArea() return Math.PI*r*r; public new double GetPerim() return Math.PI*2*r; public class Rectangle : Shape private double a, b; public Rectangle(double c, double d) a = c; b = d; public new double GetArea() return a*b; public new double GetPerim() return (2*(a+b); class Program static void Main(string args) Circle str = new Circle(3); Rectangle ch = new Rectangle(5, 10); Console.WriteLine(n0圆的半径初始化为：R=3n); Console.WriteLine( =圆的面积为：0n, str.GetArea(); Console.WriteLine( =圆的周长为：0n, str.GetPerim(); Console.WriteLine(n0初始化长方形 长为：10，宽为：5n); Console.WriteLine( =长方形面积：0n, ch.GetArea(); Console.WriteLine( =长方形周长：0n, ch.GetPerim(); Console.Read(); 编程实现一个模拟闹铃的程序，具有闹铃、继续闹铃、打会盹儿，停止闹铃的功能using System;using System.Collections.Generic;using System.Linq; using System.Text; namespace shiyan15 public class clock System.Media.SoundPlayer music; public void alarm() music = new System.Media.SoundPlayer(Track06.wav); music.Play(); public void goon() music = new System.Media.SoundPlayer(Track06.wav); music.Play(); public void rest() music.Stop(); System.Threading.Thread.Sleep(15000); music = new System.Media.SoundPlayer(Track06.wav); music.Play(); class Program static void Main(string args) clock a = new clock(); Console.WriteLine(nn=主菜单=); Console.WriteLine(nn 1 :闹铃); Console.WriteLine(nn 2 :继续闹铃); Console.WriteLine(nn 3 :稍后闹铃); Console.WriteLine(nn 4 :停止闹铃); Console.WriteLine(n请输入您要选择的编号); int i = Console.Read(); Console.ReadLine(); if (i = 1) Environment.Exit(0); a.alarm(); System.Console.Clear(); Console.WriteLine(nn=主菜单=); Console.WriteLine(nn 2 :继续闹铃); Console.WriteLine(nn 3 :稍后闹铃); Console.WriteLine(nn 4 :停止闹铃); Console.WriteLine(n您还需要的服务为); Console.ReadLine(); if (i = 2) Environment.Exit(0); a.goon(); System.Console.Clear(); Console.WriteLine(nn=主菜单=); Console.WriteLine(nn 1 : 闹铃); Console.WriteLine(nn 3 :稍后闹铃); Console.WriteLine(nn 4 :停止闹铃); Console.WriteLine(n您还需要的服务为); Console.ReadLine(); if (i = 3) Environment.Exit(0); a.rest(); System.Console.Clear(); Console.WriteLine(nn=主菜单=); Console.WriteLine(nn 1 : 闹铃); Console.WriteLine(nn 2 :继续闹铃); Console.WriteLine(nn 4 :停止闹铃); Console.WriteLine(n您还需要的服务为); Console.ReadLine(); if (i = 4) Environment.Exit(0); Console.WriteLine(已停止闹铃！); Console.ReadLine(); 创建一个点Point类，属性包括横坐标、纵坐标。要求能够完成点的移动操作、求两点距离操作，并利用运算符重载，对两个点进行比较（相等和不等）依据是两坐标点相等指它们横坐标和纵坐标分别相等。编写一个测试程序对产生的类的功能进行验证。using System;using System.Collections.Generic;using System.Linq;using System.Text; namespace _1_2 class point public double x, y; public point(double a, double b) x = a; y = b; public void move(double a, double b) x = x + a; y = y + b; public static bool operator =(point a, point b) if (a.x = b.x) & (a.y = b.y) return true; else return false; public static bool operator !=(point a, point b) if (a.x != b.x) | (a.y != b.y) return true; else return false; public double distance(point a, point b) return Math.Sqrt(a.x - b.x) * (a.x - b.x) + (a.y - b.y) * (a.y - b.y); class Program static void Main() point a = new point(1, 1); point b = new point(2, 2); Console.WriteLine(a点的坐标：（0，1）, a.x, a.y); Console.WriteLine(b点的坐标：（0，1）, b.x, b.y); Console.WriteLine(对a坐标移动2和3，按enter确认！); a.move(2, 3); Console.ReadLine(); Console.WriteLine(移动后a点得坐标是：(0,1), a.x, a.y); Console.WriteLine(a坐标移动后与b坐标距离是：0, a.distance(a, b); if (a = b) Console.WriteLine(a点和b点相等n); else Console.WriteLine(a点和b点不相等n); Console.WriteLine(对b坐标移动3和4，按enter确认！); b.move(1, 2); Console.ReadLine(); Console.WriteLine(移后b点坐标：(0,1), b.x, b.y); if (a = b) Console.WriteLine(a点和b点相等); else Console.WriteLine(a点和b点不相等); Console.ReadLine(); 定义一个顺序表SqlList类，要求能够完成在顺序表中插入元素和删除元素，确定元素在顺序表中位置，检索元素，清空表，判断表是否为空等操作。编写一个测试程序进行验证。using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace shiyan13 class SqlList private int list; private int len; public SqlList(int a, int b) list = a; len = b; public void print() for (int i = 0; i len; i+) Console.Write(00, listi); public bool insert(int c, int d) int temp = 0, i = d - 1; for (; i len; i+) temp = listi; listi = c; c = temp; if (d len | d 1) Console.WriteLine(n对不起,插入位置有误,重新输入插入位置!); return false; return true; public bool delete(int e) int j = e; for (; j len; j+) listj - 1 = listj; len-; if (e len | e 1) Console.WriteLine(n对不起，没有您要删除的元素，请重新输入您要删除的位置!n); return false; return true; public int lookup(int a) int i = 0; for (i = 0; i len; i+) if (listi = a) break; if (i = len) return -1; else return (i + 1); public int reserch(int a) int i = 0, j = 0; for (; i =0;i-) ListViewItem item=this .listView1 .SelectedItems i; this.listView1.Items.Remove(item); 编写一个简易加减、乘运算系统程序，要求在规定时间内完成规定题目数，并进行统计，给出统计结果。系统参考界面如下图所示。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 实验2._4 public partial class Form1 : Form private int total = 10;/10道题 private int curnum = 0;
