如何在Entity Framework中使用BETWEEN关键字？

Question

如何在实体框架中使用BETWEEN关键字？

这是我的SQL查询

    SELECT *
  FROM [HRM].[dbo].[meals]
  WHERE SHIFTCODE = 'Normal'
  AND 12.59 BETWEEN [STAR TIME] AND [STAR TIME]+DURATION/10;

这是我的实体框架代码。

HRMEntities HRM = new HRMEntities();
            meal ml = HRM.meals.SingleOrDefault(p => p.SHIFTCODE == "Normal");

值12.59可以是变量

Answer 1

您可以>=和<=使用DateTime来获取范围。

HRMEntities HRM = new HRMEntities();
meal ml = HRM.meals.SingleOrDefault(p => p.SHIFTCODE == "Normal" 
                                    && p.StartTime <= yourTime 
                                    && (p.StartTime + duration) >= yourtime);
