Array of long values

Posted on 2004-04-22
Last Modified: 2010-05-02
I am trying to put the id returned in a datareader into an array of long
values then put that array in a session. But I am getting this error from my
block. I want to ask if anyone could point out why I might be getting this

At least one element in the source array could not be cast down to the
destination array type.

        Dim PersonList As New ArrayList
        Dim PersonListArray As Long()

        Do While drPerson.Read()
        PersonListArray = PersonList.ToArray(GetType(Long)) <== Error

        If TypeOf drPerson Is DBNull Then
            Session.Item("lngPersomid") = 0
            Session.Item("lngPersomid") = CType(PersonListArray, Long())
        End If

try this

Dim PersonListArray() As Long    instead of Dim PersonListArray As Long()

I converted the value being return being returned from the DB from int to bigint and my code works fine now.
