C#如何将COM端口更改为指定端口

我需要更改USB串行适配器的端口号，我有以下方法来找到它，现在我需要将其端口名/COM号更改为COM11。

我需要这个，但通过C#代码：

我的电脑->管理->设备管理器->端口->通信端口->端口设置->高级->COM端口号

            ManagementObjectSearcher searcher =
                new ManagementObjectSearcher("root''WMI",
                "SELECT * FROM MSSerial_PortName");
            foreach (ManagementObject queryObj in searcher.Get())
            {
                //If the serial port's instance name contains USB 
                //it must be a USB to serial device
                if (queryObj["InstanceName"].ToString().Contains("USB"))

                    Console.WriteLine(queryObj["PortName"] + "is a USB to SERIAL adapter/converter");
                    string port = queryObj["PortName"].ToString();

                    //p.PortName = "COM11";
                    return port ;
                }
            }
            throw new Exception(Messages.PINPAD_NOT_FOUND);
        }
