如何在C语言中获取U盘的序列号#

试试这个:

// add a reference to the System.Management assembly and
// import the System.Management namespace at the top in your "using" statement.
// Then in a method, or on a button click:

ManagementObjectSearcher theSearcher = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive WHERE InterfaceType='USB'");
foreach (ManagementObject currentObject in theSearcher.Get())
{
   ManagementObject theSerialNumberObjectQuery = new ManagementObject("Win32_PhysicalMedia.Tag='" + currentObject["DeviceID"] + "'");
   MessageBox.Show(theSerialNumberObjectQuery["SerialNumber"].ToString());
}

使用Win32的解决方案 is described here

我通过查看当前对象上的属性PNPDeviceId解决了这个问题。

例如。

currentObject["PNPDeviceID"].ToString();

不确定这是否有效,但在我试过的3个U盘上它对我有效
