Question

I have a stupid yet braincracker issue about casting types. As you can see from the code I have a variable lprod_monthylReport that depending on the ytm value can be a List<Monthly_Report> or simply a Monthly_Report. I need the variable to have the same name in both cases.

var lprod_monthlyReport = new List<Monthly_Report>;

if (ytm == true)
{
   lprod_monthlyReport = _ProductRep.GetSpecificArchiveReport(prod.Prod_ID, lmonth, lyear, item.item_ID);
}
else
   lprod_monthlyReport = _ProductRep.GetSpecificYTMReport(prod.Prod_ID, item.item_ID);

The problem is that if I declare the variable inside each if (or else) section the compilers gives error because it says that the variable is already declared in this context.

I already tried casting

lprod_monthlyReport = (Monthly_Report) _ProductRep.GetSpecificArchiveReport(prod.Prod_ID, lmonth, lyear, item.Item_ID);

But it does not work. I also tried the as keyword without success.

May you please help me with this one? Thanks

This should work:
in case you’ve got a Monthly_Report just add it to the list…

    List<Monthly_Report> lprod_monthlyReport;
    if (ytm == true)
    {
       lprod_monthlyReport  = new List<Monthly_Report>();
       lprod_monthlyReport.add(_ProductRep.GetSpecificArchiveReport(prod.Prod_ID, lmonth, lyear, item.item_ID));
    }
    else{
       lprod_monthlyReport = _ProductRep.GetSpecificYTMReport(prod.Prod_ID, item.item_ID));
    }
