Question

I know in c#, to get a item from a list can use FirstOrDefault() or other functions. I am looking for a function can get most presented items from a List.

For example:

{ "a" , "a" , "a" , "b" }.MostPresents() => "a"

Is there a default function in c# (asp.net 4.0) for this?

Answer 1

var MostCommonItem = list.GroupBy(item => item)
                         .OrderByDescending(g => g.Count())
                         .Select(g => g.Key).First();
