Guys,Screenshot%20(1)
I used SharePoint custom activity for read a SharePoint list and a result is two dimensional array of dictionary<String.Object> type.

how filter specific data from this array?
Ex: there is a column - Status and with values - “Completed” and “Pending”
I want filter Completed data from the dictionary

Are there any method to resolve this problem?
