1-) C# RMOS - bilgisayarda kurulu ağda bulunan tüm yazıcı isimlerini iplerini vs alma How to get all network printers

1. Adım YaziciModel.cs

public class YaziciModel

    {

        public string Name { get; set; }

        public string Ip { get; set; }

        public string Port { get; set; }

        public string DriverName { get; set; }

        public bool WorkOffline { get; set; }

        public object PrinterState { get; set; }

        public bool isActive { get; set; }

    }

2. Adım Ping ile Yazıcı Aktifmi metodu

public static bool PingHost(string nameOrAddress)

        {

            if (nameOrAddress == null) return false;

            bool pingable = false;

            Ping pinger = null;

            try

            {

                pinger = new Ping();

                PingReply reply = pinger.Send(nameOrAddress);

                pingable = reply.Status == IPStatus.Success;

            }

            catch (PingException)

            {

                // Discard PingExceptions and return false;

            }

            finally

            {

                if (pinger != null)

                {

                    pinger.Dispose();

                }

            }

            return pingable;

        }

3. Adım Kullanılan Metot

        [HttpGet]

        public object getAllPrintNameDetail(bool isActive=false)

        {

            try

            {

                List<YaziciModel> yaziciList = new List<YaziciModel>();

                var scope = new ManagementScope(@"\root\cimv2");

                scope.Connect();

                var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_Printer");

                var results = searcher.Get();

                foreach (var printer in results)

                {

                    YaziciModel yaziciModel = new YaziciModel();

                    var portName = printer.Properties["PortName"].Value;

                    var searcher2 = new ManagementObjectSearcher("SELECT * FROM Win32_TCPIPPrinterPort where Name LIKE '" + portName + "'");

                    var results2 = searcher2.Get();

                    string isim = printer["Name"].ToString();

                    foreach (var printer2 in results2)

                    {

                        var namee = printer.Properties["Name"].Value;

                        yaziciModel.Name = namee.ToString();

                        yaziciModel.Port = printer2.Properties["PortNumber"].Value.ToString();

                        yaziciModel.Ip = printer2.Properties["HostAddress"].Value.ToString();

                    }

                    if (yaziciModel.Name == null || yaziciModel.Name == "null")

                    {

                        yaziciModel.Name = isim;

                    }

                    yaziciModel.DriverName = printer["DriverName"].ToString();

                    yaziciModel.WorkOffline = (bool)printer["WorkOffline"];

                    yaziciModel.PrinterState = printer["PrinterState"];

                    if (isActive) // hızlı sorgulasın diye bu parametriktir

                    {

                        yaziciModel.isActive = PingHost(yaziciModel.Ip);

                    }

                    //var server = new LocalPrintServer();

                    //PrintQueue queue = server.GetPrintQueue(yaziciModel.Name, Array.Empty<string>());

                    yaziciList.Add(yaziciModel);

                }

                return yaziciList;

            }

            catch (Exception ex)

            {

                return "hata 56 " + ex.Message;

            }

        }
