2.掌握使用VS2010对网页的设计。

实验步骤：1.登录页面主要代码：protected void Button1_Click(object sender, EventArgs e){string username = TextBox1.Text;string password = TextBox2.Text;string connStr = "server=(local);uid=sa;pwd=123456;database=StudentManager";SqlConnection conn = new SqlConnection(connStr);SqlCommand cmd = new SqlCommand("select * from UserInfo where username='" + username + "' and password='" + password + "'", conn);conn.Open();SqlDataReader reader = cmd.ExecuteReader();//记?录?集ˉif (reader.Read()){Response.Redirect("main.aspx");}else{Label1.Text = "用?户§名?或ò者?密ü码?错洙?误ó！?！?";}conn.Close();}2.主页面+用户信息管理页面左侧主要运用了TreeView控件，然后用户信息运用了GridView控件，链接数据源，在页面中展示用户信息，主要代码：<asp:GridView ID="GridView1"runat="server"AllowPaging="True"AllowSorting="True"AutoGenerateColumns="False"DataKeyNames="Userid"DataSourceID="SqlDataSource1"style="font-family: 楷?体?; font-size: medium"Width="550px"BackColor="#DEBA84"BorderColor="#DEBA84"BorderStyle="None" BorderWidth="1px"CellPadding="3"CellSpacing="2"><Columns><asp:BoundField DataField="Userid"HeaderText="序ò号?"ReadOnly="True"SortExpression="Userid"/><asp:BoundField DataField="UserName"HeaderText="用?户§名?"SortExpression="UserName"/><asp:BoundField DataField="Password"HeaderText="密ü码?"SortExpression="Password"/><asp:BoundField DataField="Email"HeaderText="电?子哩?邮?件t" SortExpression="Email"/><asp:CommandField ShowDeleteButton="True"ShowEditButton="True"/></Columns><FooterStyle BackColor="#F7DFB5"ForeColor="#8C4510"/><HeaderStyle BackColor="#A55129"Font-Bold="True"ForeColor="White"/><PagerStyle ForeColor="#8C4510"HorizontalAlign="Center"/><RowStyle BackColor="#FFF7E7"ForeColor="#8C4510"/><SelectedRowStyle BackColor="#738A9C"Font-Bold="True"ForeColor="White"/><SortedAscendingCellStyle BackColor="#FFF1D4"/><SortedAscendingHeaderStyle BackColor="#B95C30"/><SortedDescendingCellStyle BackColor="#F1E5CE"/><SortedDescendingHeaderStyle BackColor="#93451F"/></asp:GridView><br/><asp:SqlDataSource ID="SqlDataSource1"runat="server"ConnectionString="<%$ ConnectionStrings:StudentManagerConnectionString %>"DeleteCommand="DELETE FROM [UserInfo] WHERE [Userid] = @Userid"InsertCommand="INSERT INTO [UserInfo] ([Userid], [UserName], [Password], [Email]) VALUES (@Userid, @UserName, @Password, @Email)"SelectCommand="SELECT * FROM [UserInfo]"UpdateCommand="UPDATE [UserInfo] SET [UserName] = @UserName, [Password] = @Password, [Email] = @Email WHERE [Userid] = @Userid">3.学籍信息添加页面主要代码：protected void Button1_Click(object sender, EventArgs e){string connStr = "server=(local);uid=sa;pwd=123456;database=StudentManager";SqlConnection conn = new SqlConnection(connStr);SqlCommand cmd = new SqlCommand("insert intoStudentXj(Sno,Sname,Ssex,Sbrithday,DepartNo,ClassNo,Tel,Srxtime,xuezhi,xueli,address,youbian ,zzmm,pingjia)values('" + this.TextBox1.Text + "','" + this.TextBox2.Text + "','" + RadioButtonList1.Text + "','" + this.TextBox3.Text + "','" + this.TextBox12.Text + "','" + this.TextBox4.Text + "','" + this.TextBox5.Text + "','" + this.TextBox6.Text + "','" +this.TextBox7.Text + "','" + this.TextBox8.Text + "','" + this.TextBox9.Text + "','" +this.TextBox10.Text + "','" + DropDownList1.Text + "','" + this.TextBox11.Text + "')", conn); conn.Open();cmd.ExecuteNonQuery();conn.Close();}4.学籍信息修改本页面也是用GridView控件，与数据库连接，展示出学籍信息，然后生成“修改”，单击“修改”方可进行修改，主要代码：<asp:GridView ID="GridView1"runat="server"AllowPaging="True"AllowSorting="True"AutoGenerateColumns="False"BackColor="#DEBA84"BorderColor="#DEBA84"BorderStyle="None"BorderWidth="1px"CellPadding="3"CellSpacing="2"DataKeyNames="Sno"DataSourceID="SqlDataSource1"style="text-align: center;

conn.Open();cmd.ExecuteNonQuery();conn.Close();Label1.Text = "添?加ó成é功|！?！?！?";}7.课程信息修改添加了GridView控件，使它与数据源连接，查询课程信息分三个条件，按课程编号、课程名称、日期方可查询，主要代码：protected void Page_Load(object sender, EventArgs e){string connStr = "server=(local);uid=sa;pwd=123456;database=StudentManager";SqlConnection conn = new SqlConnection(connStr);SqlDataAdapter da = new SqlDataAdapter("select * from Course", conn);DataSet ds = new DataSet();da.Fill(ds);GridView1.DataSource = ds;GridView1.DataBind();}protected void Button1_Click(object sender, EventArgs e){string connStr = "server=(local);uid=sa;pwd=123456;database=StudentManager";SqlConnection conn = new SqlConnection(connStr);SqlDataAdapter da = new SqlDataAdapter("select * from Course where Courseid='" + this.TextBox1.Text + "' or CourseName='" + this.TextBox2.Text + "' or Datetime='" +this.TextBox3.Text + "'", conn);DataSet ds = new DataSet();da.Fill(ds);GridView1.DataSource = ds;GridView1.DataBind();}9.课程信息删除主要代码：<asp:GridView ID="GridView1"runat="server"AllowPaging="True"AutoGenerateColumns="False"BackColor="#DEBA84"BorderColor="#DEBA84"BorderStyle="None"BorderWidth="1px"CellPadding="3"CellSpacing="2"DataKeyNames="Courseid"DataSourceID="SqlDataSource1"style="text-align: center;

conn.Open();cmd.ExecuteNonQuery();conn.Close();Label1.Text = "添?加ó成é功|！?！?！?";}11.学生成绩修改主要代码：<asp:GridView ID="GridView1"runat="server"添加了GridView控件，使它与数据源连接，查询课程信息分三个条件，按课程名称、学号、姓名方可查询，主要代码：protected void Page_Load(object sender, EventArgs e){string connStr = "server=(local);uid=sa;pwd=123456;database=StudentManager";SqlConnection conn = new SqlConnection(connStr);SqlDataAdapter da = new SqlDataAdapter("select * from StudentCJ", conn);DataSet ds = new DataSet();da.Fill(ds);GridView1.DataSource = ds;GridView1.DataBind();}protected void Button2_Click(object sender, EventArgs e){string connStr = "server=(local);uid=sa;pwd=123456;database=StudentManager";SqlConnection conn = new SqlConnection(connStr);SqlDataAdapter da = new SqlDataAdapter("select * from StudentCJ where CourseName='" + this.TextBox1.Text + "' or Sno='" + this.TextBox2.Text + "' or Sname='" + this.TextBox3.Text + "'", conn);DataSet ds = new DataSet();da.Fill(ds);GridView1.DataSource = ds;GridView1.DataBind();}13.学生成绩删除主要代码：<asp:GridView ID="GridView1"runat="server"AllowPaging="True"AutoGenerateColumns="False"BackColor="#DEBA84"BorderColor="#DEBA84"BorderStyle="None"BorderWidth="1px"CellPadding="3"CellSpacing="2"DataKeyNames="Sno"DataSourceID="SqlDataSource1"style="font-family: 楷?体?;

学生管理系统程序源代码简介：学生管理系统是一种用于学校或者教育机构管理学生信息的软件系统。

它可以匡助学校管理学生的个人信息、课程信息、成绩信息等。

本文将提供一个标准格式的学生管理系统程序源代码，用于展示如何设计和实现一个简单的学生管理系统。

源代码：```python# 导入所需库import csv# 定义学生类class Student:def __init__(self, id, name, age, grade):self.id = id = nameself.age = ageself.grade = grade# 定义学生管理系统类class StudentManagementSystem:def __init__(self):self.students = []# 添加学生def add_student(self, student):self.students.append(student)# 删除学生def delete_student(self, student):self.students.remove(student)# 根据学生ID查找学生def find_student_by_id(self, id):for student in self.students:if student.id == id:return studentreturn None# 根据学生姓名查找学生def find_student_by_name(self, name):for student in self.students:if == name:return studentreturn None# 导出学生信息到CSV文件def export_to_csv(self, filename):with open(filename, 'w', newline='') as file:writer = csv.writer(file)writer.writerow(["ID", "Name", "Age", "Grade"])for student in self.students:writer.writerow([student.id, , student.age, student.grade]) # 从CSV文件导入学生信息def import_from_csv(self, filename):with open(filename, 'r') as file:reader = csv.reader(file)next(reader) # 跳过标题行for row in reader:id = row[0]name = row[1]age = row[2]grade = row[3]student = Student(id, name, age, grade)self.add_student(student)# 示例用法if __name__ == "__main__":# 创建学生管理系统对象sms = StudentManagementSystem()# 添加学生student1 = Student("001", "Alice", 18, "A")student2 = Student("002", "Bob", 17, "B")sms.add_student(student1)sms.add_student(student2)# 根据ID查找学生found_student = sms.find_student_by_id("001")if found_student:print("Found student:", found_)else:print("Student not found.")# 根据姓名查找学生found_student = sms.find_student_by_name("Bob") if found_student:print("Found student:", found_)else:print("Student not found.")# 导出学生信息到CSV文件sms.export_to_csv("students.csv")# 从CSV文件导入学生信息sms.import_from_csv("students.csv")```以上是一个简单的学生管理系统程序的源代码示例。
