i go school , 1 games , 2 music , 4

how can fastest possible way. c# 4.0 give thanks you.

the groupby method want. you'll need strings in list or implements ienumerable<string>. file.readlines suggested spender homecoming ienumerable<string> reads file line line.

var stringgroups = file.readlines("filename.txt").groupby(s => s); foreach (var stringgroup in stringgroups) console.writeline("{0} , {1}", stringgroup.key, stringgroup.count());

if want them in order of to the lowest degree (as in example) add together orderby

... foreach (var stringgroup in stringgroups.orderby(g => g.count())) ...

c# string list grouping group
