C# 返回错误的登记号码通过zkemkeeper下载考勤记录

我正在使用zkemceeper.dll从生物识别设备下载考勤记录。 这是我的密码。sdwEnrollNumber返回null或错误字符串。 但同样的程序也适用于其他计算机和其他设备

if (device2.ReadGeneralLogData(1))//read all the attendance records to the memory
                {
                    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;
                    while (device2.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
                    {
                        devece2_log(deviceIp, sdwEnrollNumber, 0, idwInOutMode, idwVerifyMode, idwYear, idwMonth, idwHour, idwHour, idwMinute, idwSecond, idwWorkcode);
                    }
                }

设备不同使用此GetGeneralExtLogData

while (device2FingersList["device_" + deviceIp].GetGeneralExtLogData(1, ref idwEnrollNumber, ref idwVerifyMode, ref idwInOutMode,
                             ref idwYear, ref idwMonth, ref idwDay, ref idwHour, ref idwMinute, ref idwSecond, ref idwWorkCode, ref idwReserved))//get records from the memory
                    {
                        devece2_log(deviceIp, idwEnrollNumber.ToString(), 0, idwInOutMode, idwVerifyMode, idwYear, idwMonth, idwDay, idwHour, idwMinute, idwSecond, idwWorkCode, "BAW");
                    }
