EF 按时查询数据怎么实现（一周内每天的小时）

for (int i = 0; i < 24; i++)
{
DateTime temp = new DateTime(endTime.Year, endTime.Month, endTime.Day, i, 0, 0);
int tag = temp.Hour;
flowWhere = (m) => m.WebInfo.Id == webId && m.DeviceType.Contains(device) && SqlFunctions.DateDiff("hh", temp, m.CurrentTime) == 0;
vifWhere = (m) => m.WebInfo.Id == webId && m.DeviceType.Contains(device) && SqlFunctions.DateDiff("hh", temp, m.AccessTime) == 0 || m.VisitSE == source || m.Address == territory;
TimeSpan ts = new TimeSpan(temp.Hour, 0, 0);
VisitorInfo model = new VisitorInfo();
model.Address = ts.ToString();
model.Age = tag;
se.Add(model);
VisitorInfo visitor = sm.GetHourByExpression(vifWhere, flowWhere);
UV.Add(visitor);
}
se = se.OrderBy(m => m.Address).ToList();
}
