Question

我尝试使用Cortana语音命令来启动我的应用程序，

但仅在应用暂停时才有效。当应用关闭时，它会显示启动画面，然后应用失败。我无法发现任何异常。

当语音命令激活应用程序时，将调用此方法，而不会调用OnLaunched。因此，我们需要与OnLaunched中的代码类似的代码

Frame rootFrame = Window.Current.Content as Frame;

if (rootFrame == null)
{
     rootFrame = new Frame();
     rootFrame.CacheSize = 1;
     Window.Current.Content = rootFrame;
     rootFrame.Navigate(typeof(MainPage));
}

使用语音指令打开应用程序时，您需要在 app.OnActivated 方法上处理它：

    protected override void OnActivated(IActivatedEventArgs e)
    {
        // Handle when app is launched by Cortana
        if (e.Kind == ActivationKind.VoiceCommand)
        {
            VoiceCommandActivatedEventArgs commandArgs = e as VoiceCommandActivatedEventArgs;
            SpeechRecognitionResult speechRecognitionResult = commandArgs.Result;

            string voiceCommandName = speechRecognitionResult.RulePath[0];
            string textSpoken = speechRecognitionResult.Text;
            IReadOnlyList<string> recognizedVoiceCommandPhrases;

            System.Diagnostics.Debug.WriteLine("voiceCommandName: " + voiceCommandName);
            System.Diagnostics.Debug.WriteLine("textSpoken: " + textSpoken);

            switch (voiceCommandName)
            ...
