如何使用 Windows Phone 8 中的对象导航? [英] How to navigate with objects in windows phone 8?

问题描述

我需要使用对象而不是字符串从一个 xaml 页面导航到另一个页面 ..

I need to navigate from one xaml page to another with an Object not a String ..

目前的代码是:

  private void Border_ManipulationStarted(object sender,    System.Windows.Input.ManipulationStartedEventArgs e)
{
     string uri = "/PhonePageOne.xaml?Text=";
     uri += txtBox.Text;
     NavigationService.Navigate(new Uri(uri, UriKind.Relative));
}

我不想在 url 中传递文本，我需要传递一个对象而不是像下面这样的对象，有什么方法可以做到这一点?

i dont want to pass a text in the url, i need to pass an object instead of that like below , and any way to do this ?

Person p = new person();
uri+=p

推荐答案

在第一页执行以下操作:

In the first page do the following:

PhoneApplicationService.Current.State["param"] = p;
NavigationService.Navigate(new Uri("/PhonePageOne.xaml", UriKind.Relative));

然后在第二次检索参数:

And in the second retrieve the parameter:

Person p = PhoneApplicationService.Current.State["param"] as Person;

PhoneApplicationService.State 字典是一个临时存储位置，它会一直存在，直到您的应用被停用.

The PhoneApplicationService.State dictionary is a temporary storage location which persists until your app is deactivated.

其他选项可以是在例如 App.xaml.cs 中声明一个静态成员，并使用它来保存一个页面中的对象并从第二个页面中检索.

Other option could be to declare a static member in, for example, App.xaml.cs and use it to save the object from one page and to retrieve from the second one.
