C#获取串口列表

参考VC方法实现的: 

       public void GetComList()
        {
            RegistryKey keyCom = Registry.LocalMachine.OpenSubKey("Hardware//DeviceMap//SerialComm");
            if (keyCom != null)
            {
                string[] sSubKeys = keyCom.GetValueNames();
                this.cmbComPort.Items.Clear();
                foreach(string sName in sSubKeys)
                {
                    string sValue = (string)keyCom.GetValue(sName);
                    this.cmbComPort.Items.Add(sValue);
                }
            }
        }
