如何使用c編程檢測USB硬盤＃

嗨我必須開發一個應用程序，使用C＃檢測USB硬盤。可能嗎？。我有一個用於檢測USB大容量存儲設備的代碼。我添加了對System.Runtime.InteropServices的引用我試圖覆蓋WndProc（）方法。我將包括片段如何使用c編程檢測USB硬盤＃

protected override void WndProc(ref Message message) 
{ 
base.WndProc(ref message); 
if ((message.Msg != WM_DEVICECHANGE) || (message.LParam == IntPtr.Zero)) 
return; 
DEV_BROADCAST_VOLUME volume = (DEV_BROADCAST_VOLUME)Marshal.PtrToStructure(message.LParam, typeof(DEV_BROADCAST_VOLUME)); 

if (volume.dbcv_devicetype == DBT_DEVTYP_VOLUME) 
{ 
switch (message.WParam.ToInt32()) 
{ 
    // New device inserted... 
    case DBT_DEVICEARRIVAL: 
     MessageBox.Show(
     string.Format("A storage device has been inserted; Drive :{0}", ToDriveName(volume.dbcv_unitmask)), "Detect USB"); 
     break; 

    // Device Removed. 
    case DBT_DEVICEREMOVECOMPLETE: 
     MessageBox.Show("Storage has been removed.", "Detect USB"); 
     break; 
    } 
    } 
} 
}

此鏈接幫助我：http://www.geekpedia.com/tutorial233_Getting-Disk-Drive-Information-using-WMI-and-Csharp.html – OhMyGeo

我開發了USB低於隨身碟的應用程序是我的聲明：

 const int WM_DEVICECHANGE = 0x0219; 
     const int DBT_DEVICEARRIVAL = 0x8000; 
     const int DBT_DEVICEREMOVALCOMPLETE = 0x8004; 
     const int DBT_DEVTYPVOLUME = 0x00000002;

下面是我的WinProc覆蓋：

 protected override void WndProc(ref Message m) 
     { 
      try 
      { 
       if (m.Msg == WM_DEVICECHANGE) 
       { 
        DEV_BROADCAST_VOLUME vol = (DEV_BROADCAST_VOLUME)Marshal.PtrToStructure(m.LParam, typeof(DEV_BROADCAST_VOLUME)); 
        if ((m.WParam.ToInt32() == DBT_DEVICEARRIVAL) && (vol.dbcv_devicetype == DBT_DEVTYPVOLUME)) 
        { 
         usb_drive = DriveMaskToLetter(vol.dbcv_unitmask).ToString(); 

         if (usb_drive.Replace(" ", "").Length > 0) 
         { 

          // USB Inserted         
         } 
        } 
        if ((m.WParam.ToInt32() == DBT_DEVICEREMOVALCOMPLETE) && (vol.dbcv_devicetype == DBT_DEVTYPVOLUME)) 
        { 
         //USB Removed 
        } 
       } 
       base.WndProc(ref m); 
      } 
      catch 
      { 

      } 
     }
