在串行端口上循环

Question

我正在使用c＃FW 4.0。 我想迭代我的计算机中的所有串行端口并获取每个端口的全名。 例如，我想看到＆＃34;多产USB到串口通讯端口（COM6）＆＃34;而不只是COM6。

这是我目前的代码，它只给我COM / 1/6等......

           string[] ports = SerialPort.GetPortNames();


        foreach (string port1 in ports)
        {
            MessageBox.Show(port1);

        }

您可以使用WMI，查看WMI Reference

Juanma回答，Here。

try
{
    ManagementObjectSearcher searcher =
        new ManagementObjectSearcher("root\\WMI",
        "SELECT * FROM MSSerial_PortName");

    foreach (ManagementObject queryObj in searcher.Get())
    {
        Console.WriteLine("-----------------------------------");
        Console.WriteLine("MSSerial_PortName instance");
        Console.WriteLine("-----------------------------------");
        Console.WriteLine("InstanceName: {0}", queryObj["InstanceName"]);

        Console.WriteLine("-----------------------------------");
        Console.WriteLine("MSSerial_PortName instance");
        Console.WriteLine("-----------------------------------");
        Console.WriteLine("PortName: {0}", queryObj["PortName"]);

        //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");
        }
    }
}
catch (ManagementException e)
{
    MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
}
