Getting Sheet Details From SmartSheet

I am trying to get the details from a row in a sheet in SmartSheet. I am using the Smartsheet scope and List Rows activities successfully. However, I can’t figure out how to get the information from the data type SmartSheet.Api.Models.Row. I have tried using for each, setting the type and item(i).Cells(1).DisplayValue where i is the index of the loop. But an error generates - For Each: Unable to cast object of type ‘Smartsheet.Api.Models.Row’ to type ‘Smartsheet.Api.Models.Row’.

If you have a Xaml example you could provide or suggestions, I would appreciate it.
Thanks.
