Erro na lição Level 3 Calculate Client Security Hash - Index was outside the bounds of the array

[taisando]

Olá boa tarde,
Estou com um erro no curso Level 3 - Advanced Training, na lição Calculate Client Security Hash.
Esse erro aparece dentro do GetTransactionData. Peguei instruções no youtube, só que não consigo sair mais desse erro. Como eu resolvo isso?

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.IndexOutOfRangeException: Index was outside the bounds of the array.

Olá @taisando, boa tarde.

Tenta antes da activity de if, colocar um log message ou message box com o texto:
“dt_WorkItems.Rows.Count & vbNewLine & in_TransactionNumber” para dizer quantas linhas tem e qual você está tentando acessar e ver se o problema pode ser na quantidade de linhas.

Eu coloquei log, e alterei o If para “in_TransactionNumber < dt_WorkItems.Count”, isso funcionou.
