[RESOLVED] [2005] Null In array

[shakti5385]

Hi all
How to check Null value in the array
See this

Dim FileName() As String = Nothing
            If Not IsDBNull(DataTable.Rows(0).Item("Document")) Then FileName = Split(DataTable.Rows(0).Item("Document"), ",")
            For Index As Integer = 0 To UBound(FileName)
                Me.lstFiles.Items.Add(Application.StartupPath & "\ShaktiProjectAttachDocument\" & FileName(Index))
            Next

if this is IsDBNull(DataTable.Rows(0).Item("Document")) Nothing then then there is Null in the array and the error will occuring here.For Index As Integer = 0 To UBound(FileName)
so How to avoid this error.
