读取另一页上的变量集 [英] Reading A Variable Set On Another Page

问题描述

我正在构建一个 Windows 手机应用程序，我需要一个设置页面.我想出了如何设置设置，但现在我需要知道如何从主页读取它们.

I'm building a windows phone app, and I need a settings page. I figured out how to set the settings but now I need to know how to read them from the main page.

所以从 MainPage.xaml.cs 我需要检查 ExitAlert 在 Settings.cs 上是真还是假，但我不知道怎么做.我确定这很简单.

So from MainPage.xaml.cs I need to check if ExitAlert is true or false on Settings.cs, and I can't figure out how. I'm sure it's something simple.

谢谢.

推荐答案

通常在 windows 中临时设置(对于特定实例)都存储在PhoneApplicationService.Current.State"中永久设置将存储在System.IO.IsolatedStorage.IsolatedStorageSettings.ApplicationSettings"

Normally in windows temporary settings (For particular instance) are stored in the "PhoneApplicationService.Current.State" and the Permanent settings will be stored in the "System.IO.IsolatedStorage.IsolatedStorageSettings.ApplicationSettings"

根据您的查询

您可以将值存储在设置页面中，如下所示

you can store the value in the settings page as follows

if(PhoneApplicationService.Current.State.Contains("ExitAlert"))
    PhoneApplicationService.Current.State["ExitAlert"] = value;
else
    PhoneApplicationService.Current.State.Add("ExitAlert", value);  

您可以从主页访问该值，如下所示

and you can access the value from the main page as follows

if(PhoneApplicationService.Current.State.Contains("ExitAlert"))
   value = (bool)PhoneApplicationService.Current.State["ExitAlert"];

if(value == true)
   Messagebox.Show("Exit alert is set");

希望它能解决您的问题.

Hope it solve your issue.
