通过zkemkeeper.dll在Windows应用程序连接到设备C＃.net

Question

我试图在网络中连接RFID和生物指标设备，我的本地IP是192.168.1.24和RFID设备IP是192.168.1.22，我正在使用Visual Studio 12一个示例窗口应用程序。连接这个设备，但它抛出一个错误：

Unable to connect the device,error code = -201

private void btnConnect_Click(object sender, EventArgs e) 
{ 

    if (txtIP.Text.Trim() == "" || txtPort.Text.Trim() == "") 
    { 
     MessageBox.Show("IP and Port cannot be null", "Error"); 
     return; 
    } 
    int idwErrorCode = 0; 
    Cursor = Cursors.WaitCursor; 

    if (btnConnect.Text == "DisConnect") 
    { 
     axCZKEM1.Disconnect(); 

     this.axCZKEM1.OnVerify -= new zkemkeeper._IZKEMEvents_OnVerifyEventHandler(axCZKEM1_OnVerify);

     this.axCZKEM1.OnEmptyCard -= new zkemkeeper._IZKEMEvents_OnEmptyCardEventHandler(axCZKEM1_OnEmptyCard); 

     bIsConnected = false; 
     btnConnect.Text = "Connect"; 
     lblState.Text = "Current State:DisConnected"; 
     Cursor = Cursors.Default; 
     return; 
    } 

    axCZKEM1.PullMode = 1; 
    bIsConnected = axCZKEM1.Connect_Net(txtIP.Text.Trim(), Convert.ToInt32(txtPort.Text.Trim())); 


    if (bIsConnected == true) 
    { 
     btnConnect.Text = "DisConnect"; 
     btnConnect.Refresh(); 
     lblState.Text = "Current State:Connected"; 
     iMachineNumber = 1;//In fact,when you are using the tcp/ip communication,this parameter will be ignored,that is any integer will all right.Here we use 1. 

     if (axCZKEM1.RegEvent(iMachineNumber, 65535))//Here you can register the realtime events that you want to be triggered(the parameters 65535 means registering all) 
     { 
      this.axCZKEM1.OnVerify += new zkemkeeper._IZKEMEvents_OnVerifyEventHandler(axCZKEM1_OnVerify); 
      this.axCZKEM1.OnAttTransactionEx += new zkemkeeper._IZKEMEvents_OnAttTransactionExEventHandler(axCZKEM1_OnAttTransactionEx); 
      this.axCZKEM1.OnNewUser += new zkemkeeper._IZKEMEvents_OnNewUserEventHandler(axCZKEM1_OnNewUser); 
      this.axCZKEM1.OnHIDNum += new zkemkeeper._IZKEMEvents_OnHIDNumEventHandler(axCZKEM1_OnHIDNum); 
      this.axCZKEM1.OnWriteCard += new zkemkeeper._IZKEMEvents_OnWriteCardEventHandler(axCZKEM1_OnWriteCard); 
      this.axCZKEM1.OnEmptyCard += new zkemkeeper._IZKEMEvents_OnEmptyCardEventHandler(axCZKEM1_OnEmptyCard); 
     } 

     MyCountFinger = 1; 
     MyCountFace = 2; 

    } 
    else 
    { 
     axCZKEM1.GetLastError(ref idwErrorCode); 
     MessageBox.Show("Unable to connect the device,ErrorCode=" + idwErrorCode.ToString(), "Error"); 
    } 
    Cursor = Cursors.Default; 
} 

请不要帮助在此先感谢

 bool isConnected; 
     try { 
      isConnected = zkem.Connect_Net(ipAddr.Text, Convert.ToInt32(4370)); 
     } catch (Exception ext) { 
      Debug.WriteLine("Холбогдож чадсангүй" + ext); 
      zkem.GetLastError(ref idwErrorCode); 
      if (idwErrorCode != 0) { 
       getError(idwErrorCode); 
      } else { 
       MessageBox.Show("No data from terminal returns!", "Error"); 
      } 
      throw new Exception(); 
     } 

     if (isConnected) { //Here you can register the realtime events that you want to be triggered(the parameters 65535 means registering all) 
      this.btnRC.Enabled = false; 
      zkem.EnableDevice(1, true); 
      zkem.RegEvent(1, 65535); 
      this.zkem.OnAttTransactionEx += new zkemkeeper._IZKEMEvents_OnAttTransactionExEventHandler(onAttTransactionEx);

          int unixDate = (Int32)(datetime.Subtract(new DateTime(1970, 1, 1))).TotalSeconds; 
          try { 
           command.Parameters.AddWithValue("@state", idwInOutMode); 
           command.Parameters.AddWithValue("@userID", Convert.ToInt32(sdwEnrollNumber));

       Debug.WriteLine("Connection Closed"); 
       Cursor = Cursors.Default; 
      } else { 
       Cursor = Cursors.Default; 
       zkem.GetLastError(ref idwErrorCode); 
       if (idwErrorCode != 0) {

       } else { 
        MessageBox.Show("No data from terminal returns!", "Error"); 
       } 
      } 
      zkem.EnableDevice(1, true); //enable the device 
      Cursor = Cursors.Default; 

      logBox.Items.Add("Холбогдлоо"); 
     } 

这里是我的连接代码。我只使用指纹。这工作很好。
