本文介绍了Windows Phone 7 (WP7) 应用中四种常见的页面间传递参数的方法：通过WEB传参、独立存储方式、PhoneApplicationService及App.xaml共享参数。每种方法都详细展示了如何在开始跳转页和转入页实现数据传递。

方法一：通过WEB传参方式进行传参

开始跳转页：

NavigationService.Navigate(new Uri("/Page/MainPage/XXXXPage.xaml?Address="+address,UriKind.RelativeOrAbsolute));

转入页：

//此方法应该在页面的Loaded方法体中实现

string address=NavigationContext.QueryString["address"];

判断是否存在：

if (NavigationContext.QueryString.ContainsKey("address"))
{
string address=NavigationContext.QueryString["address"];
}

方法二：通过独立存储方式进行传参

开始跳转页：

IsolatedStorageSettings iss = IsolatedStorageSettings.ApplicationSettings;

iss["ImageSource"] = image.source;

NavigationService.Navigate(new Uri("/Page/MainPage/XXXXPage.xaml", UriKind.Relative));

转入页：

IsolatedStorageSettings iss = IsolatedStorageSettings.ApplicationSettings;

image.Source = (BitmapImage)iss["ImageSource"];

方法三：通过PhoneApplicationService来实现传参

开始跳转页：

PhoneApplicationService myService = PhoneApplicationService.Current;

protected override void OnNavigatedFrom(NavigationEventArgs e){

      myService.State["address"] = "address";

      base.OnNavigatedFrom(e);

}

转入页：

PhoneApplicationService myService = PhoneApplicationService.Current;

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e){

    object address;

    if (myService.State.ContainsKey("address")){

        if (myService.State.TryGetValue("address", out address)){

            string address = address.ToString();

        }

    }

    base.OnNavigatedTo(e);

}

方法四：通过App.xaml进行传参（共享参数）

App.xaml:

定义一个或几个用于传参的对象，如public string Address{set;get;}

开始跳转页：

(Application.Current as App).Address= "address";

转入页：

string address=(Application.Current as App).Address;

判断是否存在：
 if (PhoneApplicationService.Current.State.ContainsKey("address"))
 {
        string address = PhoneApplicationService.Current.State["address"] as string;
 }
