时间跨度比较

是的,你需要告诉我这是新的一天。您可以使用DateTime,但也可以使用额外的一天来初始化timespan—它提供了 Parse-method 为此:

using System;
using System.Globalization;             

public class Program
{
    public static void Main()
    {
        var cdnTime = TimeSpan.Parse("23:12", CultureInfo.InvariantCulture);
        var nextTime = TimeSpan.Parse("01.00:03", CultureInfo.InvariantCulture);

        Console.WriteLine(cdnTime.TotalMinutes);
        Console.WriteLine(nextTime.TotalMinutes);
        Console.WriteLine(cdnTime.CompareTo(nextTime));
        Console.WriteLine(cdnTime < nextTime);
    }
}

另一种选择是添加后一天:

var anotherTime = TimeSpan.FromMinutes(3);
anotherTime = anotherTime.Add(TimeSpan.FromDays(1));        
Console.WriteLine(anotherTime.TotalMinutes);
