from (id=1)

how to?

i need in format

row 1 = id , date ,      min time  , max time col   = 1  , 2017-05-01, 08:00:00  , 19:00:00  row 2 = id , date ,      min time  , max time col   = 2  ,2017-05-01, 08:00:00  , 19:00:00 

groupby friend:

var query = obj.groupby(x => x.id)     .select(grp => new { id = grp.key, mindate = grp.min(x => x.date), maxdate = grp.max(x => x.date) }); 

if want specified id use where:

var id1query = query.where(x => x.id == 1);  

if expect 1 use firstordefault or singleordefault:

var id1 = query.firstordefault(x => x.id == 1);
