I have web application that updates and creates new records in a database. The application was working fine, but now I'm getting an exception: System.IndexOutOfRangeException: Index was outside the bounds of the array.

I did not code this and am not really a strong C# coder, although I can read through the code and understand the basics plus make small changes. I do not have any arrays in this particular page (that I can find).
Any suggestions on where to start troubleshooting this?

Thanks

Some of the classes you use will have indexes (a collection of some sort).

Simplest thing would be running in the debugger. You could then stop at the error and find the right place the most simple way. Otherwise you should set the options in the application (IIS) to send all errors to de browser, so you would get a  view of the callstack there.

you might be using collections, lists means classes from which values/objects can be retrieved by using indexers.
when you do debugging and the error comes then check the stack trace it will give you which function threw the error or even on which line the exception came.

if you can share that information with us we might be able to help you better
