How to assign CSV file without using ${__threadNum} in JMeter

Question

I'm facing problem with assigning the CSV file on the basis of loop count, not on the basis of thread count.

For example -> address1.csv, address2.csv......addressn.csv

So it is very easy to do the same using ${__threadNum} function (already tried and know about this but our requirement deals with loop count ) But i want do it on basis of loop Count like 1,2 .....n

1. You can use __counter() function just the same way you're using __threadNum() function. The __counter() function generates an incremented number each time it's being called.
2. Another option is going for Counter test element, if you put it inside your loop you will be able to refer incremented value by reference name. See How to Use a Counter in a JMeter Test for more details.

3. Also be aware of __iterationNum() function, it returns current Thread Group loop number. If this is something you're looking for - you can install this function via JMeter Plugins Manager as a part of Custom JMeter Functions bundle
