如何在Xamarin中的视图控制器之间传递数据

我试图在我的第一个和第二个ViewController之间传递一些数据。 我已经像这样实例化了第二个视图控制器：

 RegistrationViewController registration = new RegistrationViewController(); 

我将textfield的值设置为来自注册类的变量email，如下所示：

 registration.email = txtEmail.Text; this.NavigationController.PushViewController(registration, true); 

然后在第二个ViewController我使用它像这样：

 public string email { get; set; } txtEmail.Text = email ; 

可悲的是，我在电子邮件变量中没有值。 如何成功将数据传递给新的ViewController 。

更改控制器的代码：

  registration.email = txtEmail.Text; string password = txtPassword.Text; RegistrationViewController controller = this.Storyboard.InstantiateViewController("RegistrationViewController") as RegistrationViewController; this.NavigationController.PushViewController(registration, true); this.NavigationController.PushViewController(controller, true); 

Answer 1

尝试基于此的东西：

 SecondViewController controller = this.Storyboard.InstantiateViewController("SecondViewController") as SecondViewController; //Here you pass the data from the registerViewController to the secondViewController controller.email = registration.email; this.NavigationController.PushViewController(registration, true);
