在程序启动的时候就实时监控设备

public partial class App : Application
    { 
        protected override void OnStartup(StartupEventArgs e)
        { 
            base.OnStartup(e);
    
            GlobalMonitor.Start();
    
            if (new LoginWindow().ShowDialog() == true)
            { 
                new MainWindow().ShowDialog();
            }
            Application.Current.Shutdown();
        }
    
        protected override void OnExit(ExitEventArgs e)
        { 
            GlobalMonitor.Stop();
            base.OnExit(e);
        }
    }

public class GlobalMonitor
    { 
        public static ObservableCollection<DeviceModel> DeviceList {  get; set; } = new ObservableCollection<DeviceModel>();
    
        static bool isRunning = true;
        static Task mainTask = null;
    
        public static void Start()
        { 
            mainTask = Task.Run(async () =>
            { 
                // 获取设备信息
                //DeviceList.Add(new DeviceModel {  Name = "#1 Master device info" });
                //DeviceList.Add(new DeviceModel {  Name = "#2 Master device info" });
                //DeviceList.Add(new DeviceModel {  Name = "#3 Master device info" });
                //DeviceList.Add(new DeviceModel {  Name = "#4 Master device info" });
    
                DeviceService deviceService = new DeviceService();
                var list = deviceService.GetDevices();
                if (list != null)
                    foreach (var item in list)
                    { 
                        DeviceList.Add(item);
                    }
                //DeviceList = new ObservableCollection<DeviceModel>(list);
    
                while (isRunning)
                { 
                    await Task.Delay(100);
    
                    foreach (var item in DeviceList)
                    { 
                        if (item.CommType == 2 && item.S7 != null)// S7通信
                        { 
                            Zhaoxi.Communication.Siemens.S7Net s7Net = new Communication.Siemens.S7Net(item.S7.IP, item.S7.Port, (byte)item.S7.Rock, (byte)item.S7.Slot);
    
                            List<string> addrList = item.MonitorValueList.Select(v => v.Address).ToList();
                            var result = s7Net.Read<ushort>(addrList);
                            if (result.IsSuccessed)
                            { 
                                for (int i = 0; i < item.MonitorValueList.Count; i++)
                                { 
                                    item.MonitorValueList[i].Value = result.Datas[i];
                                }
                            }
    
                            s7Net.Close();
                        }
                    }
                }
            });
        }
    
        public static void Stop()
        { 
            isRunning = false;
            mainTask.ConfigureAwait(true);
        }
    }
