c# - Text file reader not reading until end of file -

i have following text file use position , length rule substring value of give string.

    id        b   element name                    element    c    length  position key2      01  pn    pnfn  user mid nam                    usr        1      1         2           ....about 60 rows 

here how reading the text file , apply position , length value of text file string input.

string input = "aaaaabbbbccccddddgggg......"

**edit**      var values = file.readlines("file")         .skipwhile(string.isnullorwhitespace).skip(1)                           .select(l => l.split(new[] {' ', '\t'}, stringsplitoptions.removeemptyentries));           var array1 = offsets.select(split => new                  {                      element = split[5],                      length = int.parse(split[7]),                      position = int.parse(split[8])                  });       foreach (var info in array1)         {             string substring = input.substring(info.position, info.length);              console.writeline("element: '{0}' value: '{1}'", info.element, substring);         }     

this read 14 rows , breaks loop. there doing wrong? thanks

i used sub string instead of space find exact location:

       foreach (var hashtable in item in offsets                                                  let element = item.substring(4,2)                                                  let length = convert.toint32(item.substring(6, 6))                                                  let position = item.substring(7, 4)                                                  select new hashtable                                                      {                                                          {"element", element},                                                          {"length", length},                                                          {"position", position}                                                      })
