項目進展：學生管理這部分已經進展的差不多了，調試了幾遍,改了幾個小Bug之后就沒有什么問題了,基本完成，如若后續還有一些新的功能到時候再自行加入。明天開始教師部分。

存在問題：我覺得我們的項目還是比較課堂，比較中規中矩的，還需一些閃光點來加分，例如再加入一些功能。下次小組開會的時候再討論一下。

實現的部分代碼：

MainFrm?

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 GengdanContactsMIS_WinForm {public partial class MainFrm : Form{public MainFrm(){InitializeComponent();}private void 系部管理ToolStripMenuItem_Click(object sender, EventArgs e){DepartmentFrm f = new DepartmentFrm();f.ShowDialog();}private void 專業管理ToolStripMenuItem_Click(object sender, EventArgs e){MajorFrm m = new MajorFrm();m.ShowDialog();}private void btnCancel_Click(object sender, EventArgs e){this.Close();}private void 班級管理ToolStripMenuItem_Click(object sender, EventArgs e){ClassFrm f = new ClassFrm();f.ShowDialog();}private void 學生管理ToolStripMenuItem_Click(object sender, EventArgs e){StudentFrm f = new StudentFrm();f.ShowDialog();}private void 教師管理ToolStripMenuItem_Click(object sender, EventArgs e){TeacherFrm f = new TeacherFrm();f.ShowDialog();}} }

StudentFrm

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 GengdanContactsMIS_WinForm {public partial class StudentFrm : Form{public StudentFrm(){InitializeComponent();BindClass();BindStudent();}void BindClass(){string sql = "select ClassId ,ClassName from Class";DB db = new DB();DataSet ds = db.GetDataSet(sql, "Class");cbClass.DataSource = ds.Tables["Class"];cbClass.DisplayMember = "ClassName";cbClass.ValueMember = "ClassId";}void BindStudent(){string sql = "select SNo as 學號,SName as 姓名,Sex as 性別,ClassName as 班級,BirthDate as 出生年月日,Phone as 電話,Email as 郵箱,Adress as 地址 from Student,Class where Student.ClassId=Class.ClassId";DB db = new DB();DataSet ds = db.GetDataSet(sql,"Student");dataGridView1.DataSource = ds.Tables["Student"];}private void btnAdd_Click(object sender, EventArgs e){string sql = "insert into Student(SNo,SName,Sex,ClassId,BirthDate,Phone,Email,Adress)values("+ txtSNo.Text + ",'" + txtSName.Text + "','" + txtSex.Text + "'," + cbClass.SelectedValue + ",'" + txtBirthDate.Text + "','" + txtPhone.Text + "','" + txtEmail.Text + "','" + txtAdress.Text + "')";DB db = new DB();if (db.ExecuteSQL(sql))MessageBox.Show("學生增加成功");elseMessageBox.Show("學生增加失敗，請檢查學號是否已存在");BindStudent();}private void btnSearch_Click(object sender, EventArgs e){string sql = "select SNo,SName,Sex,ClassName,BirthDate,Phone,Email,Adress from Class,Student where Class.ClassId=Student.ClassId and SName='" + txtSName.Text + "'";DB db = new DB();DataSet ds = db.GetDataSet(sql, "a");dataGridView1.DataSource = ds.Tables["a"];}private void btnCancel_Click(object sender, EventArgs e){this.Close();}} }
