linq查询结果指定列的两种方式

方式一:

var results = from product in products orderby product.Price descending select new { product.Name, product.Price };

方式二:

products.Where(pro => pro.Price < 3M).Select(s => new { s.Name, s.Price });

查询结果转换到实体里:

方式一:

var list = from q in _db.Page_AdPages where q.IsDelete == "N" orderby q.PageID select new AdPages { PageID = q.PageID, PageName = q.PageName, Flag = (Int32)q.Flag }; return list.ToList<AdPages>();

方式二:

public List<Admin_CPcompany> GetCpList() { var result = _db.Admin_CPcompany.Select(s => new Admin_CPcompany { ID=s.ID,CPname=s.CPname,AddTime=s.AddTime,IsDelete=s.IsDelete}).ToList(); return result; }
