c# - LINQ query where complete group meets a condition -

i have stored lot of text lines this:

1|1000|1|0|text message||| 1|1000|1|1|text message||| 1|1000|2|0|text message||| 1|1000|2|1|text message||| 1|1000|3|0|text message||| 1|1001|1|0|text message||| 

in collection: list<objrow> listrows

and corresponding class:

public class objrow {     private string n_par { get; set; }     private string n_rad { get; set; }     private string n_lang { get; set; }     private string n_line_mex { get; set; }     private string text_mex { get; set; }      private int n_row { get; set; } } 

i find groups of lines (grouped property n_rad, 2° pipe value) have not value n_lang == 3 (3° pipe value).

how linq?

this should want:

var groupswithoutlang3  = listrows              .groupby(o => o.n_rad)              .where(g => !g.any(o => o.n_lang == "3")); 

it selects groups without objrow n_lang == "3".
