Question

目前，我已成功连接到设备并获取日志，将其保存在数据库中，因为我还在数据库中保存更新的记录以避免任何复制的数据。但我正试图＆＃34;禁用/锁定＆＃34;在数据被提取并存储在数据库中之间的设备（提示消息说，请等待将是最顶层）。因此，如果有人使用它，他/她的记录就不会丢失。

我尝试了什么？我已经完成了这个Biometric_Device_SDK-_Programmers_Guide并遇到了这个事件，

BOOL EnableDevice(
 long dwMachineNumber ,
 BOOL bFlag );

我曾尝试在阅读日志/调用设备之前使用此事件但没有效果。等;

控制器：

  public class UserInfoController : Controller
    {
        DeviceManipulator manipulator = new DeviceManipulator();
        ZkemClient objZkeeper1 = new ZkemClient();
public ActionResult GetDevice1Logs()
        {
            isDevice1Connected = objZkeeper1.Connect_Net("xx.xxx.xxx.xxx", 4370);
            if (isDevice1Connected)
            {
                var machineNum = 1;
               //here
                objZkeeper1.EnableDevice(machineNum, false);
                ICollection<Device1Log> lstMachineInfo = manipulator.GetLogData1(objZkeeper1, machineNum);
                if (lstMachineInfo != null && lstMachineInfo.Count > 0)
                {
                    var lastRecord = db.Device1Log.OrderByDescending(x => x.DateTime).FirstOrDefault();


                    if (lastRecord != null)
                    {
                        lstMachineInfo = lstMachineInfo.Where(x => x.DateTime > lastRecord.DateTime).ToList();
                    }

                    foreach (var p in lstMachineInfo)
                    {
                        db.Device1Log.Add(p);
                    }

                    db.SaveChanges();
                }
objZkeeper1.EnableDevice(machineNum, true);

            }
    return View();

这没有触发，所以我进入了GetLogData1的定义并试图在那里实现它;

Dmanipulator：

public ICollection<Device1Log> GetLogData1(ZkemClient objZkeeper, int machineNumber)
        {

            string dwEnrollNumber1 = "";
            int dwVerifyMode = 0;
            int dwInOutMode = 0;
            int dwYear = 0;
            int dwMonth = 0;
            int dwDay = 0;
            int dwHour = 0;
            int dwMinute = 0;
            int dwSecond = 0;
            int dwWorkCode = 0;

            ICollection<Device1Log> lstEnrollData = new List<Device1Log>();
            //disabling here                
            objZkeeper.EnableDevice(machineNumber, false);
            objZkeeper.ReadAllGLogData(machineNumber);

            while (objZkeeper.SSR_GetGeneralLogData(machineNumber, out dwEnrollNumber1, out dwVerifyMode, out dwInOutMode, out dwYear, out dwMonth, out dwDay, out dwHour, out dwMinute, out dwSecond, ref dwWorkCode))
            {
                DateTime inputDate = new DateTime(dwYear, dwMonth, dwDay, dwHour, dwMinute, dwSecond);
                Device1Log objInfo = new Device1Log();
                objInfo.MachineNum = machineNumber;
                objInfo.RegisterationId = int.Parse(dwEnrollNumber1);
                objInfo.DateTime = inputDate;
                objInfo.Date = DateTime.Parse(DateTime.Parse((objInfo.DateTime).ToString()).ToString("yyyy-MM-dd"));
                objInfo.Time = DateTime.Parse(DateTime.Parse((objInfo.DateTime).ToString()).ToString("hh:mm:ss tt"));

                lstEnrollData.Add(objInfo);
            }
            objZkeeper.EnableDevice(machineNumber, true);

            return lstEnrollData;
        }

不幸的是，这些都没有奏效。我究竟做错了什么？该设备是zkteco F18。的更新： 我试图将machineNum转换为int，因为它之前是一个字符串;

if (isDevice1Connected)
            {
                var machineNum = 1;
              objZkeeper1.Beep(5000);
              objZkeeper1.EnableDevice(Convert.ToInt32(machineNum), false);
              ICollection<Device1Log> lstMachineInfo = manipulator.GetLogData1(objZkeeper1, machineNum);
                if (lstMachineInfo != null && lstMachineInfo.Count > 0){

即使Beep()事件未触发，为什么!! ：（
