课设功能描述
该学生考勤系统包含了登录、注册、学生端的请假功能，教师端对学生信息的增删改查和批假功能。
一、数据库操作类
该类主要用于后面一些功能需要对数据库操作，即需要对数据库操作的话，直接调用该类即可。
using System;
using System.Collections.Generic;
using System.Text;
using MySql.Data.MySqlClient;
namespace 学生考勤系统的设计
{
// 访问数据库的类
class MySqlAccess
{
//定义mysql连接字符串
private static string constring = "data source = localhost; database = student_attendance_system; user id = root; password = 0915; pooling = true; charset = utf8; port=3306;";
//连接mysql
private static MySqlConnection msc = new MySqlConnection(constring);
// 返回用于实现mysql命令的对象
public static MySqlCommand GetMySqlCommand(string sql)
{
//打开数据库连接
if (msc.State == System.Data.ConnectionState.Closed)
msc.Open();
return new MySqlCommand(sql, msc);
}
public static MySqlDataAdapter GetMySqlDataAdapter(string sql)
{
//打开数据库连接
if (msc.State == System.Data.ConnectionState.Closed)
msc.Open();
return new MySqlDataAdapter(sql, msc);
}
}
}
二、登录、注册功能
该功能实现起来其实也也并不是很难，登录的话，只要读取数据库的用户表，然后和输入的用户名和密码进行匹配即可，在根据该用户表的身身份字段，进入不同的客户端。 注册的话，如果操作正确，只需对数据库的用户表增加操作就行了。
1. 登录代码及截图
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using MySql.Data.MySqlClient;
namespace 学生考勤系统的设计
{
public partial class Login_Form : Form
{
//static public Login_Form login = new Login_Form(); //静态化主窗口
public static string userName;
public static string userIdentity;
public Login_Form()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
//定义sql语句
string sql = "select * from subscribers";
//调用MySqlAccess类获得实现mysql语句对象
MySqlCommand cmd = MySqlAccess.GetMySqlCommand(sql);
//执行命令
MySqlDataReader reader = cmd.ExecuteReader();
//读取数据
bool flag1 = false, flag2 = false;
while (reader.Read())
{
if (reader.GetString("id").Equals(User_Name.Text))
{
flag1 = true;
if (reader.GetString("user_password").Equals(User_Password.Text))
{
flag2 = true;
userName = reader.GetString(0);
userIdentity = reader.GetString(2);
}
}
if (flag1 && flag2)
break;
}
reader.Close();
if (flag1 && flag2)
{
if(userIdentity == "学生")
{
Student_Form student_Form = new Student_Form();
this.Hide();
student_Form.ShowDialog();
this.Close();
}
else if(userIdentity == "管理员")
{
Admin_Form admin_Form = new Admin_Form();
this.Hide();
admin_Form.ShowDialog();
this.Close();
}
else
{
Teacher_Form teacher_Form = new Teacher_Form();
this.Hide();
teacher_Form.ShowDialog();
this.Close();
}
}
else
{
if (!flag1)
MessageBox.Show("用户名错误");
else
MessageBox.Show("密码错误");
}
}
private void label1_Click(object sender, EventArgs e)
{
}
private void button2_Click(object sender, EventArgs e)
{
Register_Form register_Form = new Register_Form();
register_Form.ShowDialog();
}
}
}
2. 注册代码及截图
注册主要用于教师、辅导员、领导、院长注册，学生有教师端添加，并且点击注册时也会弹出邀请码框，邀请码由管理员生成。
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace 学生考勤系统的设计
{
public partial class Register_Form : Form
{
public Register_Form()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
textBox1.Clear();
textBox2.Clear();
textBox3.Clear();
}
private void button2_Click(object sender, EventArgs e)
{
if(comboBox1.Text .Equals(string.Empty))
{
MessageBox.Show("请选择身份！");
return;
}
if(textBox1.Text.Equals(string.Empty))
{
MessageBox.Show("用户名不能为空");
return;
}
if (textBox2.Text.Equals(string.Empty))
{
MessageBox.Show("密码不能为空");
return;
}
if (textBox2.Text != textBox3.Text)
{
MessageBox.Show("密码不一致！");
return;
}
Captcha_Form captcha_Form = new Captcha_Form();
DialogResult dialogResult = captcha_Form.ShowDialog();
if (dialogResult != DialogResult.OK)
{
MessageBox.Show("注册失败！");
return;
}
try {
string sql = "insert into subscribers values('{0}', '{1}', '{2}')";
sql = string.Format(sql, textBox1.Text, textBox2.Text, comboBox1.Text);
//MessageBox.Show(sql);
MySqlAccess.GetMySqlCommand(sql).ExecuteNonQuery();
MessageBox.Show("注册成功!");
}
catch(Exception ex)
{
MessageBox.Show("用户已存在！");
}
}
}
}
三、学生端
学生端的主页面会显示该学生的基本信息，并且有一个请假功能
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using MySql.Data.MySqlClient;
namespace 学生考勤系统的设计
{
public partial class Student_Form : Form
{
public Student_Form()
{
InitializeComponent();
}
private void Student_From_Load(object sender, EventArgs e)
{
TableShow();
}
private void TableShow()
{
string userName = Login_Form.userName;
string sql = "select student_id,student_name,class,specialty,phone_number,absence_count,late_count,early_count from student_infomation where student_id = '" + userName + "'";
//MySqlCommand cmd = MySqlAccess.GetMySqlCommand(sql);
//MySqlDataReader reader = cmd.ExecuteReader();
//创建MySqlDataAdapter对象
MySqlDataAdapter mySqlData = MySqlAccess.GetMySqlDataAdapter(sql);
//创建DataSet对象
DataSet ds = new DataSet();
//使用MySqlDataAdapter对象mySqlData将查到的结果填充到DataSet对象中
mySqlData.Fill(ds);
//设置表格控件DataSource的属性
dataGridView1.DataSource = ds.Tables[0];
//设置列标题
dataGridView1.Columns[0].HeaderText = "学号";
dataGridView1.Columns[1].HeaderText = "姓名";
dataGridView1.Columns[2].HeaderText = "班级";
dataGridView1.Columns[3].HeaderText = "专业";
dataGridView1.Columns[4].HeaderText = "电话";
dataGridView1.Columns[5].HeaderText = "旷课次数";
dataGridView1.Columns[6].HeaderText = "迟到次数";
dataGridView1.Columns[7].HeaderText = "早退次数";
//设置数据表格为只读
dataGridView1.ReadOnly = true;
//不允许添加行
dataGridView1.AllowUserToAddRows = false;
//背景为白色
dataGridView1.BackgroundColor = Color.White;
//只允许选中单行
dataGridView1.MultiSelect = false;
//整行选中
dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
}
private void button1_Click(object sender, EventArgs e)
{
Leave leave = new Leave();
leave.ShowDialog();
}
private void button2_Click(object sender, EventArgs e)
{
Login_Form lf = new Login_Form();
this.Hide();
lf.ShowDialog();
this.Close();
}
private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
}
}
}
请假功能
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using MySql.Data.MySqlClient;
namespace 学生考勤系统的设计
{
public partial class Leave : Form
{
public Leave()
{
InitializeComponent();
}
private void button2_Click(object sender, EventArgs e)
{
bool tut_leave = false, ter_leave = false, lea_leave = false, dean_leave = false;
string leaveTime;
string leaveReason;
//判断是否被选中
if (radioButton1.Checked)
{
leaveTime = radioButton1.Text;
ter_leave = true;
}
else if (radioButton2.Checked)
{
leaveTime = radioButton2.Text;
tut_leave = true;
}
else if (radioButton3.Checked)
{
leaveTime = radioButton3.Text; ;
tut_leave = true;
lea_leave = true;
}
else
{
leaveTime = radioButton4.Text;
tut_leave = true;
lea_leave = true;
dean_leave = true;
}
leaveReason = textBox1.Text;
try
{
//获取当前用户名
string userName = Login_Form.userName;
//定义sql语句，修改请假状态
string sql1, sql2, sql3;
// 更新请假状态表
sql2 = "insert into leave_state values({0}, {1}, {2}, {3}, {4})";
sql2 = string.Format(sql2, userName, tut_leave, ter_leave, lea_leave, dean_leave);
//MessageBox.Show(sql2);
MySqlAccess.GetMySqlCommand(sql2).ExecuteNonQuery(); // 获取并执行
// 更新学生表里的请假时长
sql1 = "update student_infomation set leave_state = '" + leaveTime + "' where student_id = '" + userName + "'";
//获取实现sql命令的对象
MySqlCommand cmd = MySqlAccess.GetMySqlCommand(sql1);
//执行命令
cmd.ExecuteNonQuery();
sql3 = "update student_infomation set leave_reason = '" + leaveReason + "' where student_id = '" + userName + "'";
MySqlAccess.GetMySqlCommand(sql3).ExecuteNonQuery();
MessageBox.Show("提交成功");
this.Close();
}
catch(Exception ex)
{
MessageBox.Show("你已经提交过申请");
}
}
}
}
四、管理端
管理端只包含一个生成邀请码的功能，生成的邀请码用于注册
五、教师端
教师端保函对学生信息的增删改查，修改和增加学生信息时，出勤率会自动更新，增加学生时，也会给给该学生自动生成一个账号，账号为学号，密码为123456，并且也会显示未读的消息。
