两种方式实现登录跳转新窗体

两种方式实现登录跳转新窗体

1. 直接隐藏登录窗体 显示主界面

   //验证是否有此用户
   int? flag = studentService.StudentLogin(userNameText.Text.Trim(), pwdText.Text.Trim());
   if (flag != null && flag != 0) {
   //创建实例,传值
   Home home = new Home(userNameText.Text.Trim());
   //隐藏登录窗口
   this.Hide();
   //显示主窗口
   new Home().Show();
   }
   

   public Home(string userName) {
        InitializeComponent();
        this.userName = userName;
     }
   private void Home_Load(object sender, System.EventArgs e) {
    this.textBox1.Text = this.userName;
   }
   

   //直接运行登录窗口
   Application.Run(new Login());
   

2. 在program.cs中判断当登录页面返回登录成功时 运行主窗体

   public static string userName;
   

   //验证是否有此用户
   if (flag != null && flag != 0) {
   this.DialogResult = DialogResult.OK;
   Home.userName = userNameText.Text.Trim();
   this.Close();
   

Application.EnableVisualStyles();   Application.SetCompatibleTextRenderingDefault(false);
Login login = new Login();
login.ShowDialog();
if (login.DialogResult == DialogResult.OK) {
Application.Run(new Home());
}

private void Home_Load(object sender, System.EventArgs e) { this.textBox1.Text = userName;
  }
