LINQ: Group by month and year within a datetime field

Question

I have a table with a datetime field. I want to retrieve a result set grouped by the month/year combination and the number of records that appear within that month/year. H

Answer 1

you could also do it this way

from o in yg
group o by o.OrderDate.ToString("MMM yyyy") into mg
select new { Month = mg.Key, Orders = mg }

Your result will be

{Jan 2014, 25} {Feb 2015, 15} etc...
