public string getDetails(int ddIndex)
FeederTableQuery q = lines.[ddIndex];
Where I want to pass the previously mentioned (and cast) ddlIndex variable.

Or, if you remove the "." e.g:
(how I traditionally would have thought of indexing something) it complains:
Error (active) CS0021 Cannot apply indexing with  to an expression of type 'IEnumerable<FeederTableQuery>
Feeling dumb, guidance appreciated.
