C#窗體簡單實現登陸及學生管理功能
首先我們建立一個user類
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace StudentManage
{
class User
{
string userName;
public string UserName
{
get { return userName; }
set { userName = value; }
}
string pwd;
public string Pwd
{
get { return pwd; }
set { pwd = value; }
}
string sex;
public string Sex
{
get { return sex; }
set { sex = value; }
}
int age;
public int Age
{
get { return age; }
set { age = value; }
}
}
}
接著我們還需要一個學生類
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Drawing;
namespace StudentManage
{
class Student
{
private string name;
public string Name
{
get { return name; }
set { name = value; }
}
private string sex;
public string Sex
{
get { return sex; }
set { sex = value; }
}
private string age;
public string Age
{
get { return age; }
set { age = value; }
}
private int grade;
public int Grade
{
get { return grade; }
set { grade = value; }
}
private Image touxiang;
public Image Touxiang
{
get { return touxiang; }
set { touxiang = value; }
}
}
}
設計一下登陸介面
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 StudentManage
{
public partial class CheckIn : Form
{
public CheckIn()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string name = tbxName.Text;
string pwd = tbxPwd.Text;
foreach (User item in listUser)
{
if (name!="")
{
if (pwd!="")
{
if (item.UserName==name)
{
if (item.Pwd==pwd)
{
MessageBox.Show("登入成功！");
StudentManage_Main main = new StudentManage_Main();
main.Show();
this.Hide();
}
else
{
MessageBox.Show("密碼錯誤！");
}
}
else
{
MessageBox.Show("使用者名稱錯誤！");
}
}
else
{
MessageBox.Show("密碼不能為空！");
}
}
else
{
MessageBox.Show("使用者名稱不能為空！");
}
}
}
List<User> listUser = new List<User>();
private void CheckIn_Load(object sender, EventArgs e)
{
User user1 = new User();
user1.UserName = "admin";
user1.Pwd = "123";
user1.Age = 24;
user1.Sex = "男";
listUser.Add(user1);
}
}
}
