Filter DataTable with incorrect DataType



I need to filter a datatable on values < 200. However my datatable is extracted from a web page and the values are saved as strings and not doubles. How can i change the datatypes from String to Double? I have tried using the Filter DataTable Activity but it does not work since it is not correct format. I already tried:

  1. Convert.ToDouble inside a for each row but it does not allow me to change the types.
  2. Change the DataTable Column type but this erases all the values.
  3. Using Select but not sure how to define the select criteria since “[Column]<200” will not work on string.

Please see attachement for my .xaml. You can run the entire thing and then my issues are in the end of the flow.

Try Convert.ToDouble(String)
