c# - entity framework linq query, get top N postIDs from favorite's table based on count -


i have database keeping track of favorites looks like

[id] [postid] [userid] [datefavorited]

i'm attempting write entity framework query in linq 12 postids appear in database.

i've looked @ documentation, i'm not putting how this. purpose "most favorited" page

i feel there elegant solution, i've frustrated myself point can't think of way without feting entire table that's bad idea.

in sql, be:

select     top 12     postid,     count(*) favcount     favorites group     postid order     favcount desc

in linq, believe be:

var ret = db.favorites.groupby(     fav => fav.postid ).select(     favgroup => new {         postid = favgroup.key,         count = favgroup.count()     } ).orderby(     row => row.count ).take( 12 );

with type of ret being ienumerable<anonymous{ postid, count }>.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
