  1. It is 0-based. A return question might be: why do you want to make it 1-based?

    With Extension Methods you could (if you wanted) do:

    <Extension()> Public Function GetOneBased(Of T)(ByVal list As IList(Of T), ByVal index As Integer) As T    Return list(index-1) End Function  <Extension()> Public Sub SetOneBased(Of T)(ByVal list As IList(Of T), ByVal index As Integer, ByVal value As T)    list(index-1) = value End Sub

    then use (from almost any collection):

    Dim foo = data.GetOneBased(1) data.SetOneBased(1, bar)
