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
error.

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

<code>
        Dim PersonList As New ArrayList
        Dim PersonListArray As Long()

        Do While drPerson.Read()
            PersonList.Add(drPerson("Personid"))
        Loop
        PersonListArray = PersonList.ToArray(GetType(Long)) <== Error

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

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