Linq distinct & max

Question

I have to query this table:

symbol    time
------    ----------
aaa       2013-04-18 09:10:28.000    
bbb       2013-04-18 09:10:27.000    
aaa       2013-04         


        

Answer 1

I would actually use.

void Main()
{
    var set = new [] {
        new Foo{A = "aaa", B = 1},
        new Foo{A = "bbb", B = 2},
        new Foo{A = "aaa", B = 3},
        new Foo{A = "bbb", B = 4},
    };

    var result = from x in set
                group x.B by x.A into g
                select new {id = g.Key, biggest = g.Max()};

    Console.WriteLine(result);
}
