var getr = (from d in _context.DR
join r in _context.R on d.RID equals r.RID
where HID == r.HID && cI >= d.DRD && cO < d.DRD
group d by new {d.RID, d.RGID} into g
select g);
如何将 Linq 转换为 lambda?这是我得到的:
var getr = _context.DR.Join(_context.R, x => x.RID, y => y.RID, (x, y) => new { R= x, DR= y}).Where(z => z.DR.RID== y.RID);
使用任何一种都有什么优点和缺点吗?
