LINQ获取某个表中的部分字段值

我有个新闻表

id,title,body,createtime,author,click

使用ef4.1 仅仅读取 id,title,createtime 并显示在页面上。

 

 

 public static List<NewInfo> GetHotNews()
        {
            List<NewInfo> list;
            list = (from n in db.NewInfoes
                    where n.IsTop == 1
                    orderby n.PublishTime descending
                    select new
                    {
                        Title = n.Title,
                        NewID = n.NewID,
                        PublishTime = n.PublishTime
                    }).ToList();
            return list;
        }
改为

 

 

public static List<NewInfo> GetHotNews()
        {
            List<NewInfo> list;
            list = (from n in db.NewInfoes
                    where n.IsTop == 1
                    orderby n.PublishTime descending
                   
       .Select(n => new NewInfo
                    {
                        Title = n.Title,
                        NewID = n.NewID,
                        PublishTime = n.PublishTime
                    });
            return list;
        }
