I resolve my issue!

public object ClearData(ZkemClient objZkeeper, int machineNumber, ClearFlag clearFlag)
        {
            int iDataFlag = (int)clearFlag;
            iDataFlag = 1;
            if (objZkeeper.ClearData(machineNumber, iDataFlag))
                return objZkeeper.RefreshData(machineNumber);
            else
            {
                int idwErrorCode = 0;
                objZkeeper.GetLastError(ref idwErrorCode);
                return idwErrorCode;
            }
        }

Clear the record specified by DataFlag from the device. DataFlag Type of the records to be cleared. The value ranges from 1 to 5. The meanings are as follows: 1. Attendance record 2. Fingerprint template data 3. None 4. Operation record 5. User information When the value of this parameter is 5, all user data in the device is deleted. Note: All fingerprint templates are also deleted.
