实验一： VS 环境认识和程序设计初步1.开发一个控制台应用程序，输出你的姓名和学号namespace ConsoleApplication1 class Program static void Main(string args) Console.WriteLine(my name is：zhonghua hong); Console.WriteLine(my is is 2014); Console.Read(); 2. 开发一个WINDOWS应用程序，实现加法计算和清除功能namespace WindowsFormsApplication1 public partial class Form1 : Form public Form1() InitializeComponent(); private void button1_Click(object sender, EventArgs e) textBox3.Text = (int.Parse(textBox1.Text) + int.Parse(textBox2.Text).ToString(); private void button2_Click(object sender, EventArgs e) textBox1.Text = ; textBox2.Text = ; textBox3.Text = ; 3.新建一个form窗体作为启动窗体，并在窗体上显示“学号，姓名”实验二： C#编程语言基础_上机1. 用控制台应用程序编写一个简单的学生成绩统计系统成绩：90，80，67，87，92，57，77，79，95，99；级别：优、良、中、差；条件：=90 8089 6079 =59；用数组存储成绩:循环判断（if、switch、for）；输出优、良、中、差所占成绩的百分比(WriteLine)；输出成绩排序（从高到低排序）namespace ConsoleApplication1 class Program static void Main(string args) int score; score=new int1090,80,67,87,92,57,77,79,95,99; int numA=0,numB=0,numC=0,numD=0,num=0; /*for(int i=0;i10;i+) Console.WriteLine (score0,1,i,scorei); */ for (int i = 0; i =90) numA+; else if(scorei=80) numB+; else if(scorei=60) numC+; else numD+; for (int i=0;iscore.Length;i+) switch(scorei/10) case 10: case 9:numA+;break; case 8:numB+;break; case 7: case 6:numC+;break; default:numD+;break; Console.WriteLine(numA:0 %,( 100*numA / score.Length) ); Console.WriteLine(numB:0 %, (100*numB/ score.Length) ); Console.WriteLine(numC:0 %, (100*numC/ score.Length) ); Console.WriteLine(numD:0 %, (100*numD / score.Length) ); /*Console.WriteLine (Original Score); for (int i = 0; i 10; i+) Console.WriteLine(score0,1, i, scorei); */ for (int i = 1; i score.Length; i+) for (int j = 0; j score.Length - i; j+) if (scorej scorej + 1) num = scorej; scorej = scorej + 1; scorej + 1 = num; Console.WriteLine(Original Score); for (int i = 0; i 10; i+) Console.WriteLine(score0,1, i, scorei); Console.ReadKey(); 2. 用windows应用程序设计一个存款计算器（1）利息计算：利息 p*(1+i)N 本金（2）算法流程描述：（a）从用户输入界面中分别提取存款年限、存款本金、年利率；（b）依据公式（1）计算利息总额；（c）计算总的帐户金额 ；（4）将所有要求输出的数据拼凑成符合格式要求的字符串，并输出。namespace WindowsFormsApplication1 public partial class Form1 : Form public Form1() InitializeComponent(); private void button1_Click(object sender, EventArgs e) float bj = float.Parse(textBox1.Text); float cq = float.Parse(textBox2.Text); float nll= float.Parse(textBox3.Text); double syl = bj*Math.Pow(1 + 0.01 * nll, cq); label4.Text = 本金： + bj + n存期: + cq + n年利率 + nll + n总收益 + syl; 实验四 控制程序设计1.实现在TextBox输入0-9数值，在MessageBox中输出大写汉字namespace WindowsFormsApplication1 public partial class Form1 : Form public Form1() InitializeComponent(); private void button1_Click(object sender, EventArgs e) int sum = int.Parse(textBox1.Text); switch (sum) case 0: MessageBox.Show(零); break; case 1: MessageBox.Show(壹); break; case 2: MessageBox.Show(贰); break; case 3: MessageBox.Show(叁); break; case 4: MessageBox.Show(肆); break; case 5: MessageBox.Show(伍); break; case 6: MessageBox.Show(陆); break; case 7: MessageBox.Show(柒); break; case 8: MessageBox.Show(捌); break; case 9: MessageBox.Show(玖); break; 2.实现登陆界面利用用户名和密码登陆并跳出相应MessageBox，比如可以将用户名设置为admin和shou，密码与用户名相同。 然后跳出相应MessageBoxnamespace WindowsFormsApplication2 public partial class Form1 : Form public Form1() InitializeComponent(); private void button1_Click(object sender, EventArgs e) if(comboBox1.SelectedIndex = 0) if(textBox2.Text=admin) MessageBox.Show(您输入的用户名和密码正确); else MessageBox.Show(您输入的用户名和密码错误); else if (comboBox1.SelectedIndex = 1) if (textBox2.Text = shou) MessageBox.Show(您输入的用户名和密码正确); else MessageBox.Show(您输入的用户名和密码错误); 3.实现通过在TextBox中输入关键词，查询ListBox中是否有该项名单，如果有用MessageBox告知该内容已查询到，并在ListBox中选中该选项。namespace WindowsFormsApplication3 public partial class Form1 : Form public Form1() InitializeComponent(); private void button1_Click(object sender, EventArgs e) string inStr = textBox1.Text; string strItem; strItem = new string7; for(int i=0;istrItem.Length;i+) strItemi=listBox1.Itemsi.ToString(); for (int i = 0; i strItem.Length; i+) if (strItemi.Contains(inStr) MessageBox.Show(找到了 + + strItemi + ); listBox1.SelectedIndex = i; 实验五 字符串与数组1.移除在richTextBox中输入的字符串中的逗号,namespace WindowsFormsApplication1 public partial class Form1 : Form public Form1() InitializeComponent();

foreach (char ch in str) if (ch != ,) chfinalj = ch; j+; richTextBox1.Text = new string(chfinal); 2.通过OpenFileDialog选择文件，获得该文件的路径、文件名、后缀名namespace WindowsFormsApplication2 public partial class Form1 : Form public Form1() InitializeComponent(); private void button1_Click(object sender, EventArgs e) /openFileDialog1.ShowDialog();(打开文件的另一种方法) OpenFileDialog dlg = new OpenFileDialog(); dlg.ShowDialog(); string fileAll = dlg.FileName; label5.Text = fileAll; label6.Text=fileAll.Substring(0,fileAll.LastIndexOf()+1); label7.Text = fileAll.Substring(fileAll.LastIndexOf() + 1, fileAll.LastIndexOf(.) - fileAll.LastIndexOf() -1 ); label8.Text = fileAll.Substring(fileAll.LastIndexOf(.) + 1, fileAll.Length - fileAll.LastIndexOf(.) - 1); private void Form1_Load(object sender, EventArgs e) 3.替换文本中的指定字符串namespace WindowsFormsApplication3 public partial class Form1 : Form public Form1() InitializeComponent(); private void button1_Click(object sender, EventArgs e) string str = richTextBox1.Text; richTextBox1.Text = str.Replace(textBox1.Text, textBox2.Text); 实验六：基于WinForms的上机自测系统（按书上的程序做就可以，后半部分没有）实现书pp69-87的上机自测系统namespace selfExam public partial class PrimaryExmForm : Form public PrimaryExmForm() InitializeComponent(); int ExamSecond=0;/考试用时 private void timer1_Tick(object sender, EventArgs e) ExamSecond+; this.ExamTime.Text = ExamSecond.ToString(); private void btnGrade_Click(object sender, EventArgs e) int Score = 0;/总得分 /分别评判每题 if (this.Anwser1.Text = 2000) Score = Score + 10; if (this.Anwser21A.Checked) Score = Score + 10; if (this.Anwser22C.Checked) Score = Score + 10; if (this.Anwser23.Text=PasswordChar) Score = Score + 10; if (this.Anwser24.Text = Text) Score = Score + 10; if (this.Anwser3A.Checked & this.Anwser3B.Checked & this.Anwser3C.Checked & !this.Anwser3D.Checked) Score = Score + 10; this.timer1.Enabled = false;/计时停止 this.btnGrade.Enabled = false;/评分锁定 this.TotalScore.Text = Score.ToString();/显示总得分 private void btnClose_Click(object sender, EventArgs e) this.Close();/调用Close方法关闭窗体PrimaryExmForm 实验七 窗体和控件程序设计1.设计一个简易秒表，通过一个文本框，以213:08的形式显示秒（位数随计数值变化）和毫秒，并且。通过“开始”、“停止”按钮启动或停止计时，通过一个复位按钮复位计数值以便重新开始计数namespace WindowsFormsApplication1 public partial class Form1 : Form public Form1() InitializeComponent(); DateTime time = new DateTime(2014, 11, 5, 0, 0, 0); private void button1_Click(object sender, EventArgs e) timer1.Start(); /for (int i = 0; i 10000; i+) / /textBox1.Text = (time.Hour).ToString() + 时 + (time.Minute).ToString() + 分 + (time.Second).ToString() + 秒; / private void timer1_Tick(object sender, EventArgs e) int second = 1; /for (int i = 0; ; i+) / time= time.AddSeconds(second); textBox1.Text = (time.Hour).ToString() + 时 + (time.Minute).ToString() + 分 + (time.Second).ToString() + 秒; / private void button2_Click(object sender, EventArgs e) time = new DateTime(2014, 11, 5, 0, 0, 0); textBox1.Text = (time.Hour).ToString() + 时 + (time.Minute).ToString() + 分 + (time.Second).ToString() + 秒; timer1.Stop(); （2）自行设计一个包含3个功能窗体和1个启动窗体的简单应用程序，每个窗体的功能可以自行设计，但至少包含两种窗体控件并有相应的程序设计，所有窗体通过菜单打开、工具按钮关闭。（Form Fist）namespace WindowsForms public partial class FormFirst : Form public FormFirst() InitializeComponent();
