Hi,

I am reading log file which contains huge data

C#

Timestamps Bus   MsgId
   1.8963     1     CFF8027x        Rx   d 8 0C 00 01 FC FD F0 0F 00
   1.8966     1     CFFB027x        Rx   d 8 FC FF FF D3 FC FF FF FF
   1.8967     2     CFE6CEEx        Rx   d 8 FF FF FF FF 00 00 00 00
   1.8967     3     18ECFF27x       Rx   d 8 20 12 00 03 FF EC FE 00
   1.8972     2     CFFB027x        Rx   d 8 FC FF FF D3 FC FF FF FF
   1.8973     3     CFE6CEEx        Rx   d 8 FF FF FF FF 00 00 00 00

The above is example of data
There are 4623509 lines of data

Bus with number 1 is red
Bus with number 2 is yellow
Bus with number 3 is green

I read the data using Readalllines and using constructor with 3 objects to save timestamps,bus and msgId

C#

CANMsgIdList.Add(new MsgIdTimeStampMap(CANBus, CANMsgId, timeStamp1));

MsgIdTimeStampMap is my constructor with 3 objets

I also deleted the repeated msgids using .Distict method

Now I am trying to find the messages passing from red to yellow with same msgId and different bus without passing to green or other in between

C#

int p = 233;

               
                     for (int i = 0; i < CANMsgIdList.Count; i++)
                    {

                        for (int k = 0; k < CANMsgIdList.Count; k++)
                        {
                           

                   

                        if ((gatewayRYmsgId[p] == CANMsgIdList[i].MsgId) 
                            && (CANMsgIdList[i].Bus).Equals(ConsoleApplication13.Buses.CANBusRed)
                            && (gatewayRYmsgId[p] == CANMsgIdList[k].MsgId) 
                            && (CANMsgIdList[k].Bus).Equals(ConsoleApplication13.Buses.CANBusYellow))
                           
                             {
                           
                                  {

                                    gatewayRtimeStamp.Add(CANMsgIdList[i].TimeStamp);

                                    Console.WriteLine(gatewayRtimeStamp[j]);
                                    Console.ReadKey();

                                    j++;

                                   
                                  }
                               }                           
                          }
                        }

I am getting error at line

C#

if ((gatewayRYmsgId[p] == CANMsgIdList[i].MsgId)
                           && (CANMsgIdList[i].Bus).Equals(ConsoleApplication13.Buses.CANBusRed)
                           && (gatewayRYmsgId[p] == CANMsgIdList[k].MsgId)
                           && (CANMsgIdList[k].Bus).Equals(ConsoleApplication13.Buses.CANBusYellow))

Error:Index out of range

Use the debugger to see where the index goes out of the valid range. Understand why it happened and fix it.

Dear @[Member 10408451],

As i mentioned in a comment to the Solution 1 by CHill60, you need to start with basics. Have a look at the number of your questions[^]. Most of them beat about some "Buses". You're trying to make calculations on List<t></t> generic list and arrays.

I would suggest to re-think your application and start coding from 0 (zero). I think you'll never go further in case of several lacks of knowledge, sorry...

Please, describe your problem in details:

the way you retrieve data...
what do you want to achieve?
what methods do you prefer
provide sample data
etc...

Please, make yourself a big favor and provide more information about your dilemma. We can help you to find a solution.

Solution 1

See the comment from SA about debugging.

Do that and examine the size of gatewayRYmsgId

Note that it is less than 233.

Chill, it's not worth to answer. Please, have a look at the number of questions posted by OP. OP needs to start learning...

CHill60 3-Jan-14 19:26pm

Yeah - spotted that. Answer is mainly to get it out of the list. Do you think OP will realise why 233 is significant? I was thinking of running a book on what the next post will be ;-)
