Datatable extracted from web, convert from string to int

I actually didn’t get a list, it was just a read output line by line.
I tried to follow this: How to put data from a column of datatable to list of string - #4 by Dominic

( From row in dt.AsEnumerable() Select Convert.Tostring(row(“ColumnName”)) ).ToList()

But I am not having much luck with that variable.

I am getting this error when trying to assign List
