通过LINQ比较DB的最大日期

Question

比较两个日期时间我有问题。我在我的数据库中有很多重复记录，我需要获取实际数据。我用它来获取实际数据Linq Max（）。

在数据库表格中，我有时间采用以下格式：

2017-01-03 09:19:21.220

当我尝试使用LINQ过滤实际数据时

.Where(y=> y.EditDate == DB.Table.Max(q => q.EditDate.Value))

如果我尝试让MaxD​​ate分开var

var maxDate = DB.Table.Max(q => q.EditDate);

我有这种格式的日期

03/01/2017 09:19:21

我怎样才能解决这个问题，因为如果我没有弄错的话，Linq Max（）不会返回mili和微秒。

感谢。

var <div class="width20 overflowYAuto text-center" style="padding: 5px; height: 200px;"> <div style="height:100%;"> <div class="cal_day" style="border: solid 1px black; height:90%; background-color: rgba(255,0,0,0.2)"> <p class="redText"><small>@Model.HolidayFriday</small></p> @foreach (var booking in Model.WeekEvents.ScheduleFriday.Where(e => e.SchoolClassId == @item.DetailId).OrderBy(e => e.Events.Min(ev => ev.StartDate)).ToList()) { if (@booking.Lecture) { <div class="innerbox blueBox hidden-sm hidden-xs cal_event_allteachers cal_event" onclick="showLectureSessionDetails('@booking.Id')" title="Visa mer information"> @Html.HiddenFor(b => booking.StartTimeText, new { @class = "cal_event_start_allteachers cal_event_start" }) @Html.HiddenFor(b => booking.EndTimeText, new { @class = "cal_event_end_allteachers cal_event_end" }) <div class="floatLeft"> <p class="paragraphSchadule"> <b>@booking.DisplayRow1</b><br /> <b>@booking.DisplayRow2</b><br /> <b>@booking.DisplayRow3</b><br /> <b>@booking.DisplayRow4</b><br /> <b>@booking.DisplayRow5</b><br /> </p> </div> </div> <div class="innerbox blueBox text-center visible-sm visible-xs" onclick="showLectureSessionDetails('@booking.Id')" title="Visa mer information"> <p class="paragraphSchadule"> <b>Info</b> </p> </div> } else if (@booking.FieldTrip) { <div class="innerbox yellowBox hidden-sm hidden-xs cal_event_allteachers cal_event" onclick="showFieldTripSessionDetails('@booking.Id')" title="Visa mer information"> @Html.HiddenFor(b => booking.StartTimeText, new { @class = "cal_event_start_allteachers cal_event_start" }) @Html.HiddenFor(b => booking.EndTimeText, new { @class = "cal_event_end_allteachers cal_event_end" }) <div class="floatLeft"> <p class="paragraphSchadule"> <b>@booking.DisplayRow1</b><br /> <b>@booking.DisplayRow2</b><br /> <b>@booking.DisplayRow3</b><br /> <b>@booking.DisplayRow4</b><br /> </p> </div> </div> <div class="innerbox yellowBox text-center visible-sm visible-xs" onclick="showFieldTripSessionDetails('@booking.Id')" title="Visa mer information"> <p class="paragraphSchadule"> <b>Info</b> </p> </div> } else { <div class="innerbox greenBox hidden-sm hidden-xs cal_event_allteachers cal_event" onclick="showBookingSessionDetails('@booking.Id')" title="Visa mer information"> @Html.HiddenFor(b => booking.StartTimeText, new { @class = "cal_event_start_allteachers cal_event_start" }) @Html.HiddenFor(b => booking.EndTimeText, new { @class = "cal_event_end_allteachers cal_event_end" }) <div class="floatLeft"> <p class="paragraphSchadule"> <b>@booking.DisplayRow1</b><br /> <b>@booking.DisplayRow2</b><br /> <b>@booking.DisplayRow3</b><br /> </p> </div> </div> <div class="innerbox greenBox text-center visible-sm visible-xs" onclick="showBookingSessionDetails('@booking.Id')" title="Visa mer information"> <p class="paragraphSchadule"> <b>Info</b> </p> </div> } } </div> </div> </div> 实际上存储了毫秒，但调试器中的显示使用的格式为maxDate而没有dd/MM/yyyy HH:mm:ss

在手表中试试.fff。
