Question

如何在此linq查询中添加orderby函数。我想通过计算投票显示行顺序（您可以在选择查询中看到计算）

(from e in db.FoodItems
                  join o in db.Ratings
                       on e.itemid equals o.itemid into g



           select new FoodView
              {   itemid=e.itemid,
                  caption=e.caption,
                  description=e.description,
                  price=e.price,
                  pubdate=e.pubdate,
                  imageurl=e.imageurl,
                  videourl=e.videourl,
                  itemname = e.itemname,
                  vote = (long)Math.Round((double)(g.Sum(x => (int?)x.vote) ?? 0) / g.Count(),0)


              }).Take(8).ToList();

Answer 1

.OrderBy(x => x.vote).Take(8).ToList()

Answer 2

您可以在拍摄后添加吗？

(from e in db.FoodItems
 join o in db.Ratings
         on e.itemid equals o.itemid into g
 select new FoodView
          {   itemid=e.itemid,
              caption=e.caption,
              description=e.description,
              price=e.price,
              pubdate=e.pubdate,
              imageurl=e.imageurl,
              videourl=e.videourl,
              itemname = e.itemname,
              vote = (long)Math.Round((double)(g.Sum(x => (int?)x.vote) ?? 0) / g.Count(),0)
          }).OrderBy(f => f.vote).Take(8).ToList();

Answer 3

你可以......

.Take(8).ToList().OrderBy(item => item.vote);

按顺序查询linq
