but this is my first example, how do i must to use it? padleft? or padleft? thank you ver much

Solution

  • I think all you needed to do was to switch from PadLeft to PadRight:

    Returns a new string of a specified length in which the end of the current string is padded with spaces or with a specified Unicode character.

    Since you want your column fields to be left-aligned, then you must pad right.

    file.WriteLine(
    cantidad.PadRight(5, ' ') +
   preciouni.PadRight(9, ' ') +
     desctot.PadRight(9, ' ') + 
      stotal.PadRight(9, ' '));
