Win32_PnPEntity是即插即用设备MSDN

您也可以使用驱动程序找到您的设备

            // The WMI query 
            const string QueryString = "SELECT * FROM Win32_PnPSignedDriver ";


            SelectQuery WMIquery = new SelectQuery(QueryString);
            ManagementObjectSearcher WMIqueryResults = new ManagementObjectSearcher(WMIquery);

            // Make sure results were found
            if (WMIqueryResults == null)
                return;

            // Scan query results to find port
            ManagementObjectCollection MOC = WMIqueryResults.Get();

            foreach (ManagementObject mo in MOC)
            { 
                if (mo["FriendlyName"] != null && mo["FriendlyName"].ToString().Contains("YOUR_DEVICE_NAME"))
                {}
              //Check the mo Properties to find the COM port
            }
