在 C# 中获取从小于 23:00:00 到较大的 24:00:00 之间的最接近 24:00:00 的时间

本文关键字：之间 时间 最接近 获取 小于 | 更新日期: 2023-09-27 18:32:32

我试图在午夜之前和午夜之后的两个值之间使时间更接近 24：00：00。

编辑：这只是我正在尝试做的一个例子。 在这种情况下，我应该得到这两个项目。 

var dt1 = new DateTime(2014, 11, 11, 23, 50, 00);
var dt2 = new DateTime(2014, 12, 11, 00, 50, 00);
var l = new List<DateTime>();
for (int i = 0; i < l.Count - 1; i++)
{
    TimeSpan ts1 = new TimeSpan(l[i].Hour, l[i].Minute, l[i].Second);
    TimeSpan ts2 = new TimeSpan(l[i + 1].Hour, l[i + 1].Minute, l[i + 1].Second);
    if (ts1.TotalHours <= 23 && ts2.TotalHours >= 00)
    {
        Console.WriteLine("00:00:00 - {0} {1} 'n", ts1, ts2);
    }
}

感谢您的任何帮助和建议。

你的问题很混乱，并不完全清楚你想实现什么，但我做了一些假设，并提出了我认为你可能想要的东西：

var l = new List<DateTime> {
    new DateTime(2014, 11, 11, 22, 0, 0),
    new DateTime(2014, 11, 11, 23, 45, 0),
    new DateTime(2014, 11, 11, 23, 55, 0),
    new DateTime(2014, 11, 11, 23, 59, 59),
    new DateTime(2014, 11, 12, 0, 0, 0),
    new DateTime(2014, 11, 12, 0, 4, 0),
    new DateTime(2014, 11, 12, 0, 15, 0),
    new DateTime(2014, 11, 12, 1, 0, 0),
    new DateTime(2014, 11, 12, 10, 0, 0),
};
for (int i = 0; i < l.Count - 1; i++) {
    if (l[i].TimeOfDay.TotalMinutes < 5 || l[i].TimeOfDay.TotalMinutes >= 23*60 + 55) 
        Console.WriteLine("{0} is close to midnight", l[i]);
    else
        Console.WriteLine("{0} is NOT close to midnight", l[i]);
}

我已经用一些测试数据加载了日期/时间列表，代码只是打印出每个日期/时间是否在午夜两侧的 5 分钟内。

回答你的模棱两可的问题的另一个尝试如下：

var l = new List<DateTime> {
    new DateTime(2014, 11, 11, 15, 0, 0),   // 15:00:00
    new DateTime(2014, 11, 11, 16, 0, 0),   // 16:00:00
    new DateTime(2014, 11, 11, 17, 0, 0),   // 17:00:00
    new DateTime(2014, 11, 11, 17, 20, 0),  // 17:20:00
    new DateTime(2014, 11, 11, 18, 15, 0),  // 18:15:00
    new DateTime(2014, 11, 11, 19, 0, 0),   // 19:00:00
    new DateTime(2014, 11, 11, 22, 0, 0),   // 22:00:00
    new DateTime(2014, 11, 11, 23, 45, 0),  // 23:45:00
    new DateTime(2014, 11, 11, 23, 50, 00), // 23:50:00
    new DateTime(2014, 12, 11, 00, 50, 00), // 00:50:00
    new DateTime(2014, 11, 12, 1, 0, 0),    // 01:00:00
    new DateTime(2014, 11, 12, 10, 0, 0),   // 10:00:00
};
var time = new TimeSpan(18, 0, 0); // <- Set the target time here
var offsetBefore = new TimeSpan(1, 0, 0, 0).TotalMilliseconds - time.TotalMilliseconds;
var offsetAfter = time.TotalMilliseconds * -1;
var closestBefore =
    l.Aggregate(
        (current, next) =>
            next.AddMilliseconds(offsetBefore).TimeOfDay.TotalMilliseconds > current.AddMilliseconds(offsetBefore).TimeOfDay.TotalMilliseconds
                ? next
                : current);
var closestAfter =
    l.Aggregate(
        (current, next) =>
            next.AddMilliseconds(offsetAfter).TimeOfDay.TotalMilliseconds < current.AddMilliseconds(offsetAfter).TimeOfDay.TotalMilliseconds
                ? next
                : current);
Console.WriteLine("{0} is the closest date/time before {1}.", closestBefore, time);
Console.WriteLine("{0} is the closest date/time after {1}.", closestAfter, time);
Console.WriteLine("00:00:00 - {0} {1} 'n", closestBefore, closestAfter);
// OUTPUTS:
//   11/11/2014 17:20:00 is the closest date/time before 18:00:00.
//   11/11/2014 18:15:00 is the closest date/time after 18:00:00.
//   00:00:00 - 11/11/2014 17:20:00 11/11/2014 18:15:00

这将返回列表中最接近午夜的午夜日期/时间，以及列表中最接近午夜的午夜之后的日期/时间。

希望这有帮助！

试试这个：

        var dt1 = new DateTime(2014, 11, 11, 23, 50, 00);
        var dt2 = new DateTime(2014, 12, 11, 00, 50, 00);
        var dt1temp = new DateTime(dt1.Year, dt1.Month, dt1.Day, 00, 00, 00);
        var dt2temp = new DateTime(dt2.Year, dt2.Month, dt2.Day, 00, 00, 00);
        TimeSpan time1 = new TimeSpan();
        TimeSpan time2 = new TimeSpan();
        TimeSpan time24 = new TimeSpan(24, 0, 0);
        time1 = dt1 - dt1temp;
        time2 = dt2 - dt2temp;
        if (time1.Hours >= 12) time1 = time24 - time1;
        if (time2.Hours >= 12) time2 = time24 - time2;
        string result = "";
        if (time1 < time2) result = "Time1 nearer to 00:00";
        else result = "Time2 nearer to 00:00";
