示例

以下示例实现按钮单击，该按钮显示实例中的所有 RecognizerInfo 信息。 该示例使用 SupportedAudioFormats 属性获取识别引擎配置支持的编码格式，然后在 中 MessageBox显示它。

private void recognizerInfoButton_Click(object sender, EventArgs e)   
{  
  RecognizerInfo info = _recognizer.RecognizerInfo;  
  string AudioFormats = "";  
  foreach (SpeechAudioFormatInfo fmt in info.SupportedAudioFormats)   
  {  
    AudioFormats += String.Format("       {0}\n", fmt.EncodingFormat.ToString());  
  }  
  string AdditionalInfo = "";  
  foreach (string key in info.AdditionalInfo.Keys)   
  {  
    AdditionalInfo += String.Format("      {0}: {1}\n", key, info.AdditionalInfo[key]);  
  }  
  MessageBox.Show(String.Format(  
                           "Name:                 {0 }\n" +  
                           "Description:          {1} \n" +  
                           "SupportedAudioFormats:\n" +  
                           "{2} " +  
                           "Culture:              {3} \n" +
