C# 检测应用程序首次启动windows phone

我是windows phone开发人员中的新手。我想检测用户何时首次启动我的应用程序以显示解释框，例如，通过调用：

if(firstLaunch)
showTheFrameToTheGuyBecauseHeLaunchedTheAppForTheFirstTime();

如果有人能给我们看这么小的剧本，我会非常高兴

提前谢谢大家

您可以简单地使用隔离存储设置

if(!IsolatedStorageSettings.ApplicationSettings.Contains("first"))
{
   // Do your stuff
   IsolatedStorageSettings.ApplicationSettings["first"] = true;
   IsolatedStorageSettings.ApplicationSettings.Save();
}

这段代码就可以了。

我建议您使用内置的应用程序设置

const string settingsAppLaunched = "appLaunched";

public static bool IsFirstLaunch(){
    IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings;
    return !(settings.Contains(settingsAppLaunched) && settings[settingsAppLaunched]);
}

public static bool Launched(){
    if(IsFirstLaunch()){
        IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings;
        settings.Add(settingsAppLaunched, true);
        settings.Save();
    }
}

//usage:
if(IsFirstLaunch()){
    showTheFrameToTheGuyBecauseHeLaunchedTheAppForTheFirstTime();
    Launched();
}
