此代码打破了我想是因为在 AgendaDt 和 DateTime today 有时间 。 我如何在日期前过滤此代码 。
DailyOrder todaysOrderNotReset = dailyOrders.Where(x => x.SubmittedDt == DateTime.Today && x.IsResetDone == false).First();
此代码打破了我想是因为在 AgendaDt 和 DateTime today 有时间 。 我如何在日期前过滤此代码 。
DailyOrder todaysOrderNotReset = dailyOrders.Where(x => x.SubmittedDt == DateTime.Today && x.IsResetDone == false).First();
x.SubmittedDt
应该是
x.SubmittedDt.Date
...尽管您并不真的需要 where
因为第一( 或第一( FirstOr Default)) 应该处理您想要的东西 。
dailyOrders.First(x => x.SubmittedDt.Date == DateTime.Today && x.IsResetDone == false);
试试这个
DailyOrder todaysOrderNotReset = dailyOrders.Where(x => x.SubmittedDt.Date == DateTime.Today && x.IsResetDone == false).First();
DateTime today = DateTime.Today;
DailyOrder todaysOrderNotReset = dailyOrders.First(x =>
x.SubmittedDt.Date == today && x.IsResetDone == false);
在比较当前日期/ 时间与项目集的比较时,您最好先将当前日期/ 时间读成本地变量,然后使用该一致值进行比较。否则,您将面临一个很小的风险,即当前日期/ 时间在执行过程中会发生变化,并产生意想不到的结果。
