Do you want to select all rows or all columns   Either way  you don t actually need to do anything   The DataContext has a property for each table  you can simply use that property to access the entire table   For example   foreach var line in context Orders          Do something

from row in TableA select row   Or just   TableA   In method syntax  with other operators   TableA Where row   gt  row IsInteresting     no  Select    returns the whole row    Essentially  you already are selecting all columns  the select then transforms that to the columns you care about  so you can even do things like   from user in Users select user LastName      user FirstName

I often need to retrieve  all  columns  except a few  so Select x   gt  x  does not work for me  LINQPad s editor can auto-expand   to all columns   after select    all   LINQPad expands    then I can remove not-needed columns
