Linq Top, Group By and Order By

Question

Could you help me convert this SQL statement to Linq? I have done an IN before but the GROUP BY, ORDER BY and TOP are parts I haven't done before.

SELECT TOP 300 lower(UserName) FROM UserHistory
WHERE LOWER(UserName) IN (SELECT Lower(UserName) FROM ActiveUsers)
GROUP BY LOWER(UserName)
ORDER BY MAX(Date) DESC

Answer 1

GROUP BY is done in Linq by:

group 'result here' by 'field here'

ORDER BY is done in Linq by:

.OrderBy('lambda expression here')

or

orderby //field here  ascending | descending

TOP is done in Linq by:

.Take('number here');

NOTE: the arguments are not strings, just a way to say you have to put the correct value there.
