Column does not belong to table

I am pulling data successfully from an Excel spreadsheet into a datatable, however when it gets to a column header that contains a period ".", I get the message,

Column 'Col.' does not belong to table.

and it converts Col. in datatable to Col#

What I have tried:

Dim v_Col As Integer
      Dim var As String
      Try
          v_Col = 0
          For Each r_item As DataRow In dt_city.Rows
              var = Trim(r_item.Item("Col."))
              Try
                  v_Col= Trim(r_item.Item("Col."))
              Catch exc0 As Exception
                  v_Ktn = 0
              End Try
          Next
      Catch ex As Exception
          MsgBox("column 'Col.' : " + ex.ToString)
      End Try

This is a known problem when importing/exporting data between Excel and Access (for example) - show the code you are using to populate the datatable.
Of course you could always remove the period from the column header :-)

Can you see the column in DataTable.Columns using the debugger?

I'd check the names of columns in a datatable object...

Try this:

VB

For Each r_item As DataRow In dt_city.Rows
    For Each column As DataColumn In dt_city.Columns
        MsgBox(String.Format("{0} = {1}", column.ColumnName, r_item(column))
    Next
Next
