将时间和日期与此格式 HH.MM mm/dd/yyyy 进行比较. [英] Comparing Time And Date with this format HH.MM mm/dd/yyyy.

问题描述

是否可以像这样使用军用时间和日期的格式进行比较HH.MM mm/dd/yyyy.例如:

Is it possible to compare using The format of military time and Date like this HH.MM mm/dd/yyyy. For Example:

08.25 06/10/2014 > 23.18 06/09/2014 

结果为真，因为第 10 天大于第 09 天

Result is True because the day 10 is greater than day 09

23.25 06/10/2014 > 23.30 06/10/2014 

结果为假，因为 30 分钟大于 25 分钟

Result is false because the mins 30 is greater than mins 25

24.25 06/10/2014 > 1.30 06/10/2014 

结果为真，因为 24 小时大于 1 小时

Result is true because the hrs 24 is greater than hrs 1

优先级是年份 ->月 ->日 ->小时 ->分钟.

The Priority is Year -> Month -> Day -> Hours -> mins.

推荐答案

似乎允许您使用非标准时间，例如 24.25.然后你可以使用以下策略 - 提取日期，添加时间，比较.

Seems like you are allowed to have non-standard time like 24.25. Then you can use the following strategy - extract date, add time, compare.

Public Shared Function ToDateTime(ByVal value As String) As DateTime
    Dim m As Match = Regex.Match(value, "^(?<hours>\d{1,2})\.(?<minutes>\d{2}) (?<date>\d{2}/\d{2}/\d{4})$")
    If Not m.Success Then
        Throw New ArgumentException("value")
    End If
    Dim dateOnly As DateTime = DateTime.ParseExact(m.Groups.Item("date").Value, "dd\/MM\/yyyy", CultureInfo.InvariantCulture)
    Dim hours As Integer = Integer.Parse(m.Groups.Item("hours").Value)
    Dim minutes As Integer = Integer.Parse(m.Groups.Item("minutes").Value)
    Return dateOnly.AddHours(hours).AddMinutes(minutes)
End Function

用法:

Console.WriteLine(ToDateTime("08.25 06/10/2014") > ToDateTime("23.18 06/09/2014"))
Console.WriteLine(ToDateTime("23.25 06/10/2014") > ToDateTime("23.30 06/10/2014"))
Console.WriteLine(ToDateTime("24.25 06/10/2014") > ToDateTime("1.30 06/10/2014"))
