I am looking to grab either a txt, csv, and excel file(whichever would be easier I can get whichever format from the program we are getting it from), import this data in my VS2010 program(windows form or WPF), data mine this to pick out only certain pieces, then display to user, letting them add or edit, then output to a txt file.  What is the best way to do this nowadays?

I like to import raw data in a datatable if it's contents are symmetrical (rows and columns). CSV example, but this could be txt as well if comma separated.

Dim dt As New DataTable
'add columns
dt.Columns.Add(<name of column>)
'repeat as needed

Using sr As New StreamReader(<path to file>)
  While Not sr.EndOfStream
     dt.Rows.Add(sr.Readline.Split(","c))
  End While
End Using

Open in new window


Then make LINQ queries to it and display the query. DataGridView are great for displaying datatables.
