windows-phone-8.1 – 如何在Windows Phone 8.1中收集应用程序日

这是一个例子：

App.xaml.cs

LoggingSession logSession;
LoggingChannel logChannel;

public App()
{
    this.InitializeComponent();
    this.UnhandledException += App_UnhandledException;
}

void App_UnhandledException(object sender,UnhandledExceptionEventArgs e)
{
    logChannel.LogMessage("Unhandled exception: " + e.Message);
    logSession.SaveToFileAsync(Windows.Storage.ApplicationData.Current.LocalFolder,"MainLog.log").AsTask().Wait();
}

protected override void OnLaunched(LaunchActivatedEventArgs e)
{
    logSession = new LoggingSession("MainLogSession");
    Resources["MainLogSession"] = logSession;

    logChannel = new LoggingChannel("AppLogChannel");
    logSession.AddLoggingChannel(logChannel);
}

MainPage.xaml.cs中

LoggingChannel logChannel;

public MainPage()
{
    this.InitializeComponent();

    var logSession = (LoggingSession)Application.Current.Resources["MainLogSession"];
    logChannel = new LoggingChannel("MainPageLogChannel");
    logSession.AddLoggingChannel(logChannel);
    logChannel.LogMessage("MainPage ctor",LoggingLevel.Information);
}

我强烈建议在2013年的构建会议期间观看Making your Windows Store Apps More Reliable主题演讲,其中Harry Pierson更详细地演示了这些新API(包括使用后台任务将日志文件上传到后端服务器,后台任务在手机连接到交流电源时执行).
