[2008] Access [SQL] Getting Last Row?

[Wesley008]

Dim table As DataTable = DS.Tables(0)
            Dim TableRow As DataRow = table.Rows(table.Rows.Count - 1)
            If DS.Tables(0).Rows.Count > 0 Then
                NewTableName = DS.Tables(0).Rows(TableRow).Item("CourseID").ToString()
            End If

Can't Convert Integer into DataRow

How do I make TableRow a Integer while keeping the table.Rows(table.Rows.Count -1) ? I'm trying to get the last index then set it to add to that on a NEW TABLE
