如何使用組合框更改我的Windows窗體應用程序的聲音文件？

Question

我正在開發一個Windows窗體應用程序。目前我正在爲Windows窗體應用程序的設置方面工作。在設置表單上，我可以切換我的應用程序的提示音。默認聲音代碼如下

public String defaultAlertTone = Path.GetDirectoryName(Application.ExecutablePath) + "\\Sounds\\applause-2.wav"; 

至於設置，我已經包括2個默認音調供用戶通過組合框進行選擇。對於組合框的代碼如下，

private void comboBoxSound_SelectedIndexChanged(object sender, EventArgs e) 
    { 
     if (comboBoxSound.SelectedIndex == 0) 
     { 
      ReportStatus("Alert tone changed to 'Beep(1)'!"); 
      backgroundFormObject.getSetting().defaultAlertTone = Path.GetDirectoryName(Application.ExecutablePath) + "\\Sounds\\beep-1.wav"; 
     } 
     else 
     { 

      ReportStatus("Alert tone changed to 'Beep(2)'!"); 
      backgroundFormObject.getSetting().defaultAlertTone = Path.GetDirectoryName(Application.ExecutablePath) + "\\Sounds\\beep-2.wav"; 
     } 

     string appPath = Path.GetDirectoryName(Application.ExecutablePath); 

     Stream stream = File.Open(appPath + "\\setting.sd", FileMode.Create); 
     BinaryFormatter bFormatter = new BinaryFormatter(); 


     bFormatter.Serialize(stream, backgroundFormObject.getSetting()); 
     stream.Close(); 
    } 

爲什麼，每當我選擇另一色調，和我一起玩的聲音，效果還是一樣的原始提示音是掌聲。在我玩之前是否必須等待文件加載完成？

設法解決它自己使用下面的代碼

private void comboBoxSound_SelectedIndexChanged(object sender, EventArgs e) 
    { 
     if (comboBoxSound.SelectedIndex == 0) 
     { 
      ReportStatus("Alert tone changed to 'Beep(1)'!"); 
      settingObject.defaultAlertTone = Path.GetDirectoryName(Application.ExecutablePath) + "\\Sounds\\beep-1.wav"; 
     } 
     else 
     { 

      ReportStatus("Alert tone changed to 'Beep(2)'!"); 
      settingObject.defaultAlertTone = Path.GetDirectoryName(Application.ExecutablePath) + "\\Sounds\\beep-2.wav"; 
     } 

     string appPath = Path.GetDirectoryName(Application.ExecutablePath); 

     Stream stream = File.Open(appPath + "\\setting.sd", FileMode.Create); 
     BinaryFormatter bFormatter = new BinaryFormatter(); 


     bFormatter.Serialize(stream, settingObject); 
     stream.Close(); 
    }
