使用C＃中的WMI查詢通過驅動器盤符獲取硬盤驅動器序列號

Question

我有以下代碼，它可以很好地通過Win32_DiskDrive中的模型字符串值獲取硬盤驅動器序列號。但我需要通過分配的驅動器號來獲取序列號。這可能嗎？如果是這樣如何？

public string GetDriveSerial(string model) 
{ 
    string serial = string.Empty; 
    string query = "SELECT * FROM Win32_DiskDrive WHERE Model = '" + model + "'"; 
    try 
    { 
     using (var results = new ManagementObjectSearcher("root\\CIMV2", query)) 
     { 
      foreach (ManagementObject result in results.Get()) 
      { 
       serial = result["SerialNumber"].ToString(); 
      } 
     } 
    } 
    catch (Exception ex) 
    { 
     MessageBox.Show(ex.Message); 
    } 
    return serial; 
}

你可以試試這個：

public static string GetSerialFromDrive(string driveLetter) 
{ 
    try 
    { 
     using (var partitions = new ManagementObjectSearcher("ASSOCIATORS OF {Win32_LogicalDisk.DeviceID='" + driveLetter + 
              "'} WHERE ResultClass=Win32_DiskPartition")) 
     { 
      foreach (var partition in partitions.Get()) 
      { 
       using (var drives = new ManagementObjectSearcher("ASSOCIATORS OF {Win32_DiskPartition.DeviceID='" + 
                 partition["DeviceID"] + 
                 "'} WHERE ResultClass=Win32_DiskDrive")) 
       { 
        foreach (var drive in drives.Get()) 
        { 
         return (string)drive["SerialNumber"]; 
        } 
       } 
      } 
     } 
    } 
    catch 
    { 
     return "<unknown>"; 
    } 

    // Not Found 
    return "<unknown>"; 
} 

這預計這樣的驅動器盤符： 「C：」， 「d：」 ...... 原代碼可以發現here。
