如何在Windows 8手机导航的对象？ [英] How to navigate with objects in windows phone 8?

问题描述

我需要从一个XAML页面导航到另一个对象不是一个字符串..

目前的代码是：

 私人无效Border_ManipulationStarted（对象发件人，System.Windows.Input.ManipulationStartedEventArgs E）
 {
字符串URI =/PhonePageOne.xaml?Text=  
 URI + = txtBox.Text; 
 NavigationService.Navigate（新的URI（URI，UriKind.Relative））; 
} 
  

我不希望传递一个文本中的网址，我需要传递一个对象，而不是像之下，没有办法做到这一点？

 人员P =新的人（）; 
 URI + = P 
  

解决方案

在第一页做到以下几点：

  PhoneApplicationService.Current.State [参数] = p; 
 NavigationService.Navigate（新的URI（/ PhonePageOne.xaml，UriKind.Relative））; 
  

和第二检索参数：

 者p = PhoneApplicationService.Current.State [参数]的人; 
  

的

PhoneApplicationService.State 词典是暂时的存储位置这一直持续到您的应用程序被停用。

其他选项可能宣布在静态成员，例如 App.xaml.cs ，并用它来从一​​个网页保存对象，并从第二个取回。

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

present code is :

  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));
}

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

解决方案

In the first page do the following:

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

And in the second retrieve the parameter:

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

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

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.
