Question

I am trying to use a nice near object setter, but have null issues.

My code right now:

var Result = new RefundReplyObject
{
    AuthorisationNumber = reply.refundResponse.transactionDetails.authorisationNumber,
    ChargeValue = reply.refundResponse.transactionDetails.totalAmount.amount, 
    Message = reply.refundResponse.transactionDetails.message,
    ReconciliationReference = reply.refundResponse.transactionDetails.reconciliationReference,
    SettlementDate = reply.refundResponse.transactionDetails.settlementDate,
    Status = TransactionStatusToLocalModel(reply.refundResponse.transactionDetails.status),
    TransactionReference = reply.refundResponse.transactionDetails.transactionReference
};

BUT … ‘totalAmount’ might be null. So, I get errors.

Is there a neat way to handle this, so that if ‘totalAmount’ is null, then set chargevalue to zero?

Answer 1

How about a ternary operator, that checks to see if total amount is null. If it isn’t, then use it’s amount, otherwise 0.

ChargeValue = (reply.refundResponse.transactionDetails.totalAmount != null) ? reply.refundResponse.transactionDetails.totalAmount.amount : 0,
