io - Read Text File Using Certain Algorithm in C# -

hi folks googling 1 more hours.i did not find relevant, have text file this

 s.no code   l description                             interaction text     1 xxxx   x xxxxxxxxxxxxx                           xxxxxxxxxxxxxxxxxxxxxxxxxxxxx     2 xxxxxx x xxxxxxxxxxxxxxxxxxxxxxx                 xxxxxxxxxxxx     3 xxxx   x xxxxxxxxxxxxxxx                         xxxxxxxxxxxxxxxxxxxxxxxxxx     4 xxxxx  x xxxxxxxxx xxxxxxx xxxxxxxxxxxxxxxxxx    xxxxxxxxxxxxxxxxxxxxxxxxxxxxx     5 xxxxxx x xxxxxxxxxxxxxxx xxxxxxxx xxxxxxxxx      xxxxxxxxxx xxxxxxxxxxx xxxxx     6 xxxxxx x xxxxxxxxxxxxxxxx xxxxxxxx xxxxx xxxxxxx xxxxxxxxxx xxxxxxxx xxxxxxx 

i reading contents using code,

 string path = @"c:\temp\mytest.txt"; string[] lines = file.readalllines(path); 

but stuck when split columns.any appreciated

in short

how split every columns using fixed length of string?

going cut example save time:

s.no     code 1 xxxx   x    2 xxxxxx x    3 xxxx   x      4 xxxxx  x     5 xxxxxx x      6 xxxxxx x 

first define max lengths of each column, in example:

 list<int> maxlengths = new list<int> { 2,7,4};   list<list<string>> columns = new list<list<string>>(); // we'll save columns 

iterate on lines , use lengths know part of substring cut off:

        foreach (string line in lines)         {             list<string> linescolumns = new list<string>();             int lastindex = 0;             foreach (int maxlength in maxlengths)             {                 linescolumns.add( line.substring(lastindex, maxlength));                lastindex += maxlength;             }         } 

obviously simplified, you'll have work on error handling.
