I’m trying to use Read Column activities from different excel files.
The outputs of Read Column which have more than two elements are working.
The outputs which have only one element do not work.
For example, message box (output.FIrst().ToString()) throw NullReferenceException.
(However, output.count().Tostring() says “1”)
Do you have solutions?
IEnumerable variables should have more than two elements?
