c# - max date record in LINQ

Question

I have this table named sample with these values in MS Sql Server:

 ID    Date    Description
1    2012/01/02 5:12:43    Desc1
2    2012/01/02 5:12:48    Desc2
3    2012/01/03 5:12:41    Desc3
4    2012/01/03 5:12:43    Desc4

Now I want to write LINQ query that result will be this:

4    2012/01/03 5:12:43    Desc4

I wrote this but it doesn't work:

List<Sample> q = (from n in  Sample.Max(T=>T.Date)).ToList();

Answer 1

O(n log n):

var result = Sample.OrderByDescending(t => t.Date).First();

O(n) – but iterates over the sequence twice:

var max = Sample.Max(t => t.Date);
var result = Sample.First(t => t.Date == max);

Or you can use MoreLINQ which has MaxBy method which is O(n)
