If Condition：
String.IsNullOrEmpty(Queue_Test_Data_item(“LoanRate”).ToString) or String.IsNullOrWhiteSpace(Queue_Test_Data_item(“LoanRate”).ToString)

※Queue_Test_Data_item is a Dictionary type variable for storing items retrieved from the queue…

Hi

Pls try with this single expression itself

String.IsNullOrEmpty(Queue_Test_Data_item(“LoanRate”).ToString)

And make sure there is a field named LoanRate in that queue item

Hi,

Can you try the following expression?

Queue_Test_Data_item("LoanRate") is Nothing OrElse String.IsNullOrEmpty(Queue_Test_Data_item("LoanRate").ToString) OrElse String.IsNullOrWhiteSpace(Queue_Test_Data_item("LoanRate").ToString)

Or the following might be better.

(Not Queue_Test_Data_item.ContainsKey("LoanRate")) OrElse String.IsNullOrEmpty(Queue_Test_Data_item("LoanRate").ToString) OrElse String.IsNullOrWhiteSpace(Queue_Test_Data_item("LoanRate").ToString)

Regards,

Thank you for your quick reply.

I tried the code below this one, and there was no error.

Queue_Test_Data_item("LoanRate") is Nothing OrElse String.IsNullOrEmpty(Queue_Test_Data_item("LoanRate").ToString) OrElse String.IsNullOrWhiteSpace(Queue_Test_Data_item("LoanRate").ToString)

But, When I tried this, I got the same null exception.

(Not Queue_Test_Data_item.ContainsKey("LoanRate")) OrElse String.IsNullOrEmpty(Queue_Test_Data_item("LoanRate").ToString) OrElse String.IsNullOrWhiteSpace(Queue_Test_Data_item("LoanRate").ToString)

I wasn’t quite sure what was causing the this, but I was able to resolve the error using the first method., thank you very much!!

Hi,

Second code checks if key named “LoanRate” exists. As it seems the key exists In this case, the first one will be solution.

FYI: This expression uses OrElse operator. As it helps you in this case, see the following in detials.
