WP7 + IsoStore +失去价值 [英] WP7 + IsoStore + loosing value

问题描述

大家好......我在使用IsolatedStorageSettings.ApplicationSettings时遇到了一个奇怪的行为......

当我将数据保存到商店并离开时我的应用程序中的当前页面我可以正常从IsoStore重新加载数据...

当我点击 ""或"搜索"按钮，然后点击"后退"按钮按钮重新加载应用程序，存储的数据不再可用...

 

我正在使用Imports System.Io。 IsolatedStorage指令位于页面顶部，代码如下：

保存

        Dim appSettings As IsolatedStorageSettings = IsolatedStorageSettings.ApplicationSettings

       如果appSettings.Contains（" SavedGame"）则为
            appSettings（" SavedGame"）= currentGame

       否则为
            appSettings.Add（" SavedGame"，currentGame）

       结束如果

后退

        Dim appSettings As IsolatedStorageSettings = IsolatedStorageSettings.ApplicationSettings

 

       如果appSettings.Contains（" SavedGame"）则为
           返回CType（appSettings（" SavedGame"），SavedGame）

       否则为
           什么都不返回
       结束如果

 

PS：我正在使用模拟器对此进行测试...所以我的问题是......有什么这段代码错了，或者只是模拟器的行为？

谢谢，

问候，

Victor

Hi everybody... I'm facing a strange behavior when using the IsolatedStorageSettings.ApplicationSettings...

When I save my data to the store and navigate away from the current page in my app I can reload the data from IsoStore normally...

When I hit the "start" or "search" buttons and then hit the "back" button to reload the application, the data stored is no longer available...

 

I'm using the Imports System.Io.IsolatedStorage directive on top of page and the code bellow:

Saving

        Dim appSettings As IsolatedStorageSettings = IsolatedStorageSettings.ApplicationSettings

        If appSettings.Contains("SavedGame") Then
            appSettings("SavedGame") = currentGame
        Else
            appSettings.Add("SavedGame", currentGame)
        End If

Retreiving

        Dim appSettings As IsolatedStorageSettings = IsolatedStorageSettings.ApplicationSettings
 
        If appSettings.Contains("SavedGame") Then
            Return CType(appSettings("SavedGame"), SavedGame)
        Else
            Return Nothing
        End If

 

PS: I'm using the emulator to test this... so my question is... is there anything wrong in this code or it's just the emulator behavior?

Thanks,

Regards,

Victor
