public event EventHandler<System.Speech.Recognition.AudioSignalProblemOccurredEventArgs> AudioSignalProblemOccurred;

member this.AudioSignalProblemOccurred : EventHandler<System.Speech.Recognition.AudioSignalProblemOccurredEventArgs> 

Public Custom Event AudioSignalProblemOccurred As EventHandler(Of AudioSignalProblemOccurredEventArgs) 

事件類型

EventHandler<AudioSignalProblemOccurredEventArgs>

範例

下列範例會定義可收集事件相關資訊的 AudioSignalProblemOccurred 事件處理常式。

private SpeechRecognizer recognizer;

// Initialize the speech recognition engine.
private void Initialize()
{
  recognizer = new SpeechRecognizer();

  // Add a handler for the AudioSignalProblemOccurred event.
  recognizer.AudioSignalProblemOccurred +=
    new EventHandler<AudioSignalProblemOccurredEventArgs>(
      recognizer_AudioSignalProblemOccurred);
}

// Gather information when the AudioSignalProblemOccurred event is raised.
void recognizer_AudioSignalProblemOccurred(object sender, AudioSignalProblemOccurredEventArgs e)
{
  StringBuilder details = new StringBuilder();

  details.AppendLine("Audio signal problem information:");
  details.AppendFormat(
    " Audio level:               {0}" + Environment.NewLine +
    " Audio position:            {1}" + Environment.NewLine +
    " Audio signal problem:      {2}" + Environment.NewLine +
    " Recognition engine audio position: {3}" + Environment.NewLine,
    e.AudioLevel, e.AudioPosition,  e.AudioSignalProblem,
    e.recoEngineAudioPosition);

  // Insert additional event handler code here.
}

備註

若要取得發生的問題，請使用 AudioSignalProblem 相關聯 AudioSignalProblemOccurredEventArgs 的 屬性。

當您建立 AudioSignalProblemOccurred 事件的委派時，您會識別將處理事件的方法。 若要使事件與您的事件處理常式產生關聯，請將委派的執行個體 (Instance) 加入至事件。 除非您移除委派，否則每當事件發生時就會呼叫事件處理常式。 如需事件處理常式委派的詳細資訊，請參閱 事件和委派。
