我可以使用NavigationContext.QueryString设置参数吗？ （Windows Phone）

Question

Can I pass value to Navigation Context like this:

NavigationContext.QueryString["param1"] = "PARAM1";

Is it a good way to set parameter?

Answer 1

First of all, why you need to store some parameters in NavigationContext.QueryString ? There are exists another good places for this.

If you want to pass parameters to another page, use this:

NavigationService.Navigate(new Uri("SomePage.xaml?param1=PARAM1"))

if you need to save some values to the state dictionary, you can use PhoneApplicationService.Current.State (global) or PhoneApplicationPage.State (page specific)
