ZKEmkeeper：事件不触发，DLL看起来像没有工作

Question

我stucked为尝试使用zkemkeeper SDK上使用一个InBios（控制器）指纹一个应用程序中使用了一段时间。虽然我试图触发一些事件没有发生，我只是创建了一个控制台应用程序来测试SDK，然后才开始实施ASP.NET MVC这里是我的代码，我第一次连接到设备，然后我添加事件OnAttTransactionEx有人可以指出我做错了什么。

这里是我的代码：

private static void Main(string[] args) 
    { 
     CZKEMClass zkem = new CZKEMClass(); 
     int idwErrorCode = 0; 
     const string ipAddr = "10.0.1.240"; 
     bool isConnected; 
     try 
     { 
      isConnected = zkem.Connect_Net(ipAddr, Convert.ToInt32(4370)); 
     } 
     catch (Exception ext) 
     { 
      Console.WriteLine("Erro: " + ext); 
      zkem.GetLastError(ref idwErrorCode); 
      if (idwErrorCode != 0) 
      { 
       zkem.GetLastError(idwErrorCode); 
      } 
      else 
      { 
       Console.WriteLine("No data from terminal returns!"); 
      } 
      throw new Exception(); 
     } 

     if (isConnected) 
     { 
      //Here you can register the realtime events that you want to be triggered(the parameters 65535 means registering all) 
      zkem.EnableDevice(1, true); 
      zkem.RegEvent(1, 65535); 
      zkem.OnAttTransactionEx += axCZKEM1_OnAttTransactionEx; 

      string sdwEnrollNumber = ""; 
      int idwVerifyMode = 0; 
      int idwInOutMode = 0; 
      int idwYear = 0; 
      int idwMonth = 0; 
      int idwDay = 0; 
      int idwHour = 0; 
      int idwMinute = 0; 
      int idwSecond = 0; 
      int idwWorkcode = 0; 

      zkem.EnableDevice(1, false); //disable the device 
      if (zkem.ReadGeneralLogData(1)) 
      { 
       //read all the attendance records to the memory 
       while (zkem.SSR_GetGeneralLogData(1, out sdwEnrollNumber, out idwVerifyMode, 
        out idwInOutMode, out idwYear, out idwMonth, out idwDay, out idwHour, 
        out idwMinute, out idwSecond, ref idwWorkcode)) 
       { 
        //get records from the memory 

        DateTime datetime = new DateTime(idwYear, idwMonth, idwDay, idwHour, idwMinute, idwSecond); 
        int unixDate = (int) datetime.Subtract(new DateTime(1970, 1, 1)).TotalSeconds; 
        try 
        { 
         Console.WriteLine(idwInOutMode); 
         Console.WriteLine(sdwEnrollNumber); 
         Console.WriteLine(unixDate); 
        } 
        catch (Exception ex) 
        { 
         //ignored 
        } 
        try 
        { 
         Console.WriteLine("inserted: " + 
              $"{idwYear}/{idwMonth}/{idwDay} {idwHour}:{idwMinute}:{idwSecond}.000"); 
        } 
        catch (Exception ex) 
        { 
        } 
       } 
      } 
      Console.WriteLine("Fim"); 
     } 
     else 
     { 
      zkem.GetLastError(ref idwErrorCode); 
      if (idwErrorCode != 0) 
      { 
       zkem.GetLastError(idwErrorCode); 
      } 
      else 
      { 
       Console.WriteLine("No data from terminal returns!"); 
      } 
     } 
     zkem.EnableDevice(1, true); 

     Console.WriteLine("Teste"); 
     do 
     { 
      while (!Console.KeyAvailable) 
      { 
      } 
     } while (Console.ReadKey(true).Key != ConsoleKey.Escape); 
    } 

    public static void axCZKEM1_OnAttTransactionEx(string sEnrollNumber, int iIsInValid, int iAttState, 
     int iVerifyMethod, int iYear, int iMonth, int iDay, int iHour, int iMinute, int iSecond, int iWorkCode) 
    { 
     Console.WriteLine("Finger Recognized"); 
    }

您必须使用STA线程。

Thread TT = new Thread(() => 
{ 
    CZKEMClass zkem = new CZKEMClass(); 
    Application.Run(); 
}); 
TT.IsBackground = true; 
TT.SetApartmentState(ApartmentState.STA); 
TT.Start(); 

然后创建事件。 ZKEM事件在STA线程上触发。
