使用C＃中的WMI查询通过驱动器盘符获取硬盘驱动器序列号

Question

我有以下代码，它可以很好地通过Win32_DiskDrive中的模型字符串值获取硬盘驱动器序列号。但我需要通过分配的驱动器号来获取序列号。这可能吗？如果是这样如何？

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; 
}

你可以试试这个：

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>"; 
} 

这预计这样的驱动器盘符： “C：”， “d：” ...... 原代码可以发现here。
