在lambda表达式中插入对象属性

Question

我跟随Linq对实体的声明。

var records = from c in db.l_rate_his
              select new testing { namec.l_rate.name, labo = c.rate};

我正在尝试将其转换为lambda表达式。我已经走到了这一步

var records1 = db.l_rate_his.Include(p => p.labor_rate).ToArray();

如何完成lambda表达式以包含对象属性？

您的查询

var records = from c in db.l_rate_his
              select new testing { namec.l_rate.name, labo = c.rate};

相当于

var records = db.l_rate_his
                .Select(c => new testing { namec.l_rate.name, labo = c.rate });
