Continue program after encountering error

[Member 14474607]

Hello - I had records to be processed at a time, and the 4th record had an issue. The entire program failed, not processing the rest of the records which had no issue. How can I can continue the program processing the good records? Thanks!!

I have a catch block in the code which catches all exceptions and writes to log file. How can I make it that the program continues processing the good records instead of not processing the entire batch.

There is no specific way to answer you because we have no idea how you are processing the records. One way to do it is to process one record at a time and put that code in a try catch, inside the loop. That way the loop will continue. However, if the problem is that the database is not available, for example, then it's going to throw an exception for every single record you are processing.

You haven't supplied any relevant code so it's impossible to tell you with any accuracy. But, the try/catch block should surround only the processing of a single record, NOT THE ENTIRE LIST OF THEM.

Ask what you want the try-catch to do; retry the current item, or skip it and progress to the next. Retrying should be limited.

To add to what the others have said, you might also want to look at why the record failed - what did it contain that you didn't expect? Was it something you should have expected, or been able to handle? For example, if a user is to enter a page full of information and a single item is wrong, you shouldn't invalidate the whole page - just get the user to enter the right value. We can't see your screen, access your HDD, or read your mind - so we have no idea what your code is doing, or how it is doing it; but graceful error handling is an important part of any app!
