任何幫助？

Answer 1

後很難我得到的解決方案

(from e in db.Holidays 
group e by new {e.Title, e.Flag} 
into g 
select new AllEventViewModel 
{ 
start = g.Max(e=>e.Date), 
end = g.Min(e => e.Date), 
title = g.Key.Title, 
Flag = g.Key.Flag 
}).AsEnumerable(); 

Answer 2

var results = db.holidays.GroupBy(g => new { g.Title, g.Flag }).Select(k => new 
{ 
    MinDate = k.Min(a => a.Date), 
    StartDate = k.FirstOrDefault().StartDate, 
    MaxDate = k.Max(b => b.Date), 
    EndDate = k.FirstOrDefault().EndDate, 
    Title = k.Key.Title, 
    Flag = k.Key.Flag 
}).ToList();
