How to add strings to a ienumerable<System.String>

Hi, I am trying to add arguments (strings) to a Systems.Collections.Generic.IEnumerable<System.String>. My ultimate purpose is to add this collection as a variable attachments for a Send Exchange Mail Message activity. I have tried a loop to iterate through the folder + an invoke Method, however it did not work, as the “Add” is not part of IEnumerable. Could you please help me here? Thanks in advance!
