vb.net Fill array with dataset

Question

I'm trying to fill a class array with a DataSet that I retrieved from a table

If I populate a textbox directly from the DataSet it works perfectly, but population of the array gives me this exception, If arry(i).ArrID is an Integer

system.NullReferenceException

The line is this:

arry(i).ArrID = ds.Tables(0).Rows(i).Item(0)

If arry(i).ArrID is a string, the Exception reads

Object reference not set to an instance of an object.

I'm new to VB and would appreciate some help, thank you for your time.

In VBA, the Tables object has a starting index of 1 , so if you're using an index of 0 , you're referencing a table that doesn't exist, hence the Null Reference. You should also change the Item(0) reference, and ensure i is never set to 0 . [Source]
