Question

如果以太网连接是全双工或半双工，我试图在C＃Winforms应用程序中显示。我不确定是否要检查任何API。我一直在使用下面的代码来获取NetworkInterfaces

NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
 foreach (NetworkInterface adapter in adapters)
        {
            IPInterfaceProperties properties = adapter.GetIPProperties();
            IPv4InterfaceStatistics stats = adapter.GetIPv4Statistics();
            Console.WriteLine(adapter.Description);
            Console.WriteLine("Speed .....: {0}",adapter.Speed);                    
        }

上面的代码为我提供了适配器的描述，速度，NetworkInterfaceType，OperationalStatus等。我要查找的是连接是全双工还是半双工。

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            //string deviceName = "TP-Link Wireless N PCI Express Adapter";

            ManagementScope scope = new ManagementScope("\\\\.\\ROOT\\StandardCimv2");

            ObjectQuery query = new ObjectQuery($"SELECT * FROM MSFT_NetAdapter");// WHERE DriverDescription = \"{deviceName}\"");

            using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query))
            {
                using (ManagementObjectCollection queryCollection = searcher.Get())
                {
                    foreach (ManagementObject m in queryCollection)
                    {
                        Console.WriteLine($"{m["DriverDescription"]} : {m["FullDuplex"]}");
                    }
                }
            }

            Console.ReadKey();
        }
    }
}
