Question

I’m experiencing this error…

variable ‘paymentLine’ of type ‘Xrm.sb_directdebitpaymentline’ referenced from scope ”, but it is not defined

… when I attempt to do ‘paymentLines.ToList()’ after the following code:

var payments = from payment in Crm.sb_directdebitpayments
               where payment.statuscode == 1
                     && Crm.sb_directdebitmandates.Any(mandate =>
                                                       mandate.sb_directdebitmandateid ==
                                                       payment.sb_directdebitmandateid &&
                                                       mandate.statuscode == 1)
               select payment;

var paymentLines = from paymentLine in Crm.sb_directdebitpaymentlines
                   where paymentLine.sb_paymentsent == isSent
                         && paymentLine.statuscode == status
                         && payments.Any(payment =>
                                         payment.sb_directdebitpaymentid ==
                                         paymentLine.sb_directdebitpaymentid &&
                                         payment.statuscode == 1)
                   select paymentLine;

If anyone has any ideas on how to fix this, I’d be very grateful!

Answer 1

It is a curious combination of query syntax and extension methods (Any).

It looks like a variation on the capture loop var problem. Execution of paymentLines is deferred, so what value does the captured paymentLine line have when the payments.Any( ) is executed?

Try to rewrite it as a Join.
