C#管理系统，登录页面，学生页面，老师页面
管理系统：大体分成三个页面
登录页面，学生页面，老师页面
三个页面之间是相通的，可通过切换账号，登录其他页面
老师，学生的账号，密码我是给的固定值。
老师的账号：201966 密码：123abc
学生的账号：123456 密码：123123
首先看登录页面
这是代码
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;
namespace 管理系统
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
comboBox1.SelectedIndex = 0;
comboBox1.DropDownStyle = ComboBoxStyle.DropDownList;
}
const string tid = "201966",tpwd="123abc";
const string sid = "123456", spwd="123123";
private void button1_Click(object sender, EventArgs e)
{
string id = maskedTextBox1.Text;
string pwd = textBox1.Text;
if (id == ""||pwd=="")
{
MessageBox.Show("请输入必填项");
return;
}
string selecttype = comboBox1.SelectedItem.ToString();
switch (selecttype)
{
case "老师":
if (tid.Equals(id) && tpwd.Equals(pwd))
{
Form2 fr = new Form2();
fr.Show();
this.Hide();
}
else
{
MessageBox.Show("登录失败！");
}
break;
case "学生":
if (sid.Equals(id) && spwd.Equals(pwd))
{
Form3 fm = new Form3();
fm.Show();
this.Hide();
}
else
{

}
break;
default:
