[Solved]-how to search between comma separated field in linq-LINQ,C#

for csv splitting i advise you to use any csv parser, not simply use string.split method.

string[] input = { "1,2,4,5", "1,4,3,6", "2,3,4,5", "1,4" };

var result = input.where(l => l.split(',').any(s => new[] { "2", "3" }.contains(s)));
