请教一个WPF浏览器应用程序页面传值和跳转的问题

你可以用Application.Current.Properties在整个程序范围内保存一些值，就像ASP.NET的Session对象一样。

public partial class TaskPage : Page
{
...
void okButton_Click(object sender, RoutedEventArgs e)
{
// Accept task when Ok button is clicked
TaskPageReturn(true);
}

void cancelButton_Click(object sender, RoutedEventArgs e)
{
// Cancel task
TaskPageReturn(false);
}

void TaskPageReturn(bool taskResult)
{
Application.Current.Properties["TaskResult"] = taskResult;

// Return to calling page
this.NavigationService.GoBack();
}
}


...

public partial class CallingPage : Page
{
...
void callingPage_Loaded(object sender, RoutedEventArgs e)
{
// If a task happened, get task result
if (Application.Current.Properties["TaskResult"] == null) return;
bool taskResult = (bool)Application.Current.Properties["TaskResult"];

// Remove result and data
Application.Current.Properties["TaskResult"] = null;
}
...
}
