如何在Windows Phone 8.1中收集应用程序日志？

Question

我是Windows手机平台的新手.有什么可用的东西像android中的logcat用于收集日志吗？提前感谢.

Windows 8.1引入了新类来简化日志记录.这些类是LoggingChannel,LoggingSession和他人.

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年建立会议期间观看让您的Windows应用商店应用程序更可靠的主题演讲,其中Harry Pierson更详细地演示这些新API(包括使用后台任务将日志文件上传到后端服务器,该任务在手机启动时执行连接到交流电源).
