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());
           

1. 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;
  }
