Convert CSV column to Decimal for filtering in VB.NEt DataTable

Last Modified: 2012-05-09
I am reading a CSV file into a DataSet and then creating a datatable so that I can apply a filter to the rows.
My problem is that I need to apply a price range based filter but all columns are held as strings.
Can I convert a column to decimal for the purpose of this filter?  I thought I could CAST the value in my select statement but this does not work.
