使用C＃在Metro应用程序保存用户设置 [英] Saving user settings in Metro app using C#

问题描述

我想在Metro应用程序编写用户选择的设置，在本地文件夹。我也做了code如下，但它不工作。

I want to write user selected settings in Metro app, in Local Folder. I have done the code as below, but it is not working.

在code键保存设置：

The code to save settings:

        void OnUnloaded(object sender, RoutedEventArgs args)
    {
        //code to save app settings.
        var localSettings = ApplicationData.Current.LocalSettings;
        localSettings.Values["playerPosition"] = playerPosition;
        localSettings.Values["aiPosition"] = aiPosition;
        localSettings.Values["selectedLevel"] = selectedLevel;
    }

在code阅读设置：

The code to read settings:

            var localSettings = ApplicationData.Current.LocalSettings;
        if ((localSettings.Values["playerPosition"]) == null)
        {
            localSettings.Values["playerPosition"] = 1;
            localSettings.Values["aiPosition"] = 1;
            localSettings.Values["selectedLevel"] = "1";

            playerPosition = aiPosition = 1;
            selectedLevel = "1";
        }
        else
        {
            playerPosition = (int)localSettings.Values["playerPosition"];
            aiPosition = (int)localSettings.Values["aiPosition"];
            selectedLevel = (string)localSettings.Values["selectedLevel"]; ----

显然我应该保存此localSettings变量在一个文件中。但是，我无法找到code做到这一点。此外，为Unload事件的好地方这样做，或者我应该把它移到OnNavigatedFrom事件？任何帮助，请？

Clearly I am supposed to save this localSettings variable in a file. But, I am unable to find the code to do that. Also, is Unload event a good place to do it, or should I move it to OnNavigatedFrom event? Any help, please?

推荐答案

我还没有尝试过自己还，但也许你可以看看这个样本（应用程序设置的样品）： HTTP：//$c$c.msdn.microsoft.com / windowsapps /应用程序 - 设置 - 采样1f762f49

I haven't tried it myself yet, but maybe you could check out this sample (App settings sample): http://code.msdn.microsoft.com/windowsapps/App-settings-sample-1f762f49

它使用 Windows.UI.ApplicationSettings 的命名空间。

编辑： 看完<一href="http://www.$c$cguru.com/csharp/.net/using-local-storage-with-c-and-xaml-in-windows-8-metro-apps.html"相对=nofollow>这个帖子和快速入门 MSDN上，在我看来，你并不需要保存文件，因为LocalSettings处理这个的吗？你没有看到这种行为？

After reading this post and the quickstart on MSDN, it seems to me you do not need to save a file, because the LocalSettings handle this for you? Are you not seeing this behavior?
