我借助了一些网络资源创建了以下程序来制作Jarvis:

namespace JarvisFile1{    public partial class Form1 : Form    {        private void Form1_Load(object sender, EventArgs e)        {            _recognizer.SetInputToDefaultAudioDevice();            _recognizer.LoadGrammar(new Grammar(new GrammarBuilder(new Choices(File.ReadAllLines(@"C:\Users\Nelson\Documents\JarvisCommands\greetings.txt")))));            _recognizer.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(_recognizer_SpeechRecognized);            _recognizer.RecognizeAsync(RecognizeMode.Multiple);        }        SpeechRecognitionEngine _recognizer = new SpeechRecognitionEngine();        SpeechSynthesizer JARVIS = new SpeechSynthesizer();        string QEvent;        string ProcWindow;        double timer = 10;        int count = 1;        Random rnd = new Random();        public Form1()        {            InitializeComponent();        }        void _recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)        {            int ranNum = rnd.Next(1, 10);            string speech = e.Result.Text;            switch (speech)            {                //GREETINGS                case "hello":                case "hello jarvis":                    if (ranNum < 6) { JARVIS.Speak("Hello sir"); }                    else if (ranNum > 5) { JARVIS.Speak("Hi"); }                    break;                case "goodbye":                case "goodbye jarvis":                case "close":                case "close jarvis":                    JARVIS.Speak("Until next time");                    Close();                    break;                case "jarvis":                    if (ranNum < 5) { QEvent = ""; JARVIS.Speak("Yes sir"); }                    else if (ranNum > 4) { QEvent = ""; JARVIS.Speak("Yes?"); }                    break;            }        }    }}

编译器开始时完美地编译了它，然后给出了以下错误消息:

管理调试助手 ‘RaceOnRCWCleanup’ 在 ‘C:\Users\Nelson\Documents\Visual Studio 2013\Projects\JarvisFile1\JarvisFile1\bin\Debug\JarvisFile1.vshost.exe’ 中检测到问题。

附加信息: 尝试释放正在使用的RCW。RCW正在当前线程或其他线程上使用。尝试释放正在使用的RCW可能会导致损坏或数据丢失。

作为编程初学者，我不太确定这意味着什么。任何帮助解决这个问题都将不胜感激。如果需要，我可以提供进一步的调试日志。我使用的是Windows 8和Visual Studio 2013。
