c# - How to get last entered textdata from textfile? -

-

does 1 know how fetch last entered textdata textfile 1 know

var readtxt = file.readalltext(@"d:\file\log.txt");

simple answer: it's impossible unless have prior version of file. imagine, file is

    b   c

what's happened before? a added or d removed or b changed e? if have previous version can compute called edit distance, e.g.:

https://en.wikipedia.org/wiki/levenshtein_distance

before after          c      b          c

edit distance (levenshtein one) 1 , edit operation b inserted. however, edit distance doesn´t guarantee exact editing procedure, provides most probable one.
