[c＃]从usb密钥获取序列号 [英] [c#] get the serial number from a usb key

问题描述

如何获得连接到PC的USB密钥的序列号，型号......？


这样的东西：

 ManagementObjectSearcher USB =  new  ManagementObjectSearcher（  SELECT * FROM Win32_DiskDrive）; 
 ManagementObjectCollection USBinfo = USB.Get（）; 
  string  info =  ; 
  foreach （ManagementObject MO  in  USBinfo）
 {
 info = （ string ）MO [  SerialNumber ]。 
} 
 

但这给了我磁盘的序列号，而不是usb密钥。

解决方案

尝试查询 WMI 类 Win32_LogicalDisk ，它有一个名为 VolumeSerialNumber的属性。其他属性（如 DriveType 和 MediaType ）将帮助您识别类型或驱动器。使用属性 PNPDeviceID ，可以将其追踪到物理USB设备信息。

How to get the serial number, model,... of the usb key connected on to pc?

Something like this:

ManagementObjectSearcher USB = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
          ManagementObjectCollection USBinfo = USB.Get();
          string info = "";
          foreach (ManagementObject MO in USBinfo)
          {
              info = (string)MO["SerialNumber"];
          }

But this gives me the serial number for disk, not usb key.

Try querying for the WMI class Win32_LogicalDisk, it has one property called VolumeSerialNumber. Other properties like DriveType and MediaType will help you identifying the type or drive. With the property PNPDeviceID it could be possible to track it down to the physical USB device information.
