我试图找到时间范围之间的持续时间并将其转换为小时,分钟和秒。应添加的小时数不应转换为24小时。如果有50小时30分30秒它应该显示为50:30:30,如果分钟持续时间超过59,它应该在几秒钟内增加到几小时。
请参阅完整的代码。这两种方法都没有给出正确的答案。方法GetSumOfDuration将0.30视为0.3,因此它没有给出正确的答案。方法GetSumOfDurationFromSecond在超过24小时的差异时失败。

答案 0 :(得分:2)
这应该给出日期之间的总小时数。
DateTime dt1 = new DateTime(2016, 1, 1);
DateTime dt2 = new DateTime(2016, 1, 5);
TimeSpan difference = dt2 - dt1;
int totalDaysToHours = difference.Days * 24;
Console.WriteLine((difference.Hours + totalDaysToHours) + " hours " + difference.Minutes + " Minutes " + difference.Seconds + " seconds" );
Console.ReadKey();
答案 1 :(得分:0)
您可以通过减去操作来确定差异的时间跨度。
TimeSpan time1 = TimeSpan.Parse(date1);
TimeSpan time2 = TimeSpan.Parse(date2);
TimeSpan difference = time1 - time2;
int hours = difference.Hours;
int minutes = difference.Minutes;
答案 2 :(得分:0)
您可以从结束时间中减去开始时间。 结果将是Timespan对象。
// Set startime example to one hour ten minutes and 30 seconds ago
DateTime startTime = DateTime.Now.AddSeconds(-4230);
DateTime endTime = DateTime.Now;
TimeSpan elapsedTime = endTime-startTime;
// Print out the elapsed time in hour:minutes:seconds to string
string result = elapsedTime.TotalHours + ":" + elapsedTime.Minutes + ":" + elapsedTime.Seconds
请注意,TimeSpan为例如Hours和TotalHours提供了属性。小时数可以在0-23之间(当值超过23时,属性天数会增加)而TotalHours则提供完整小时数
答案 3 :(得分:0)
我同意ThomasVoß你应该使用Timespan。但是,TotalHours应该被转换为int以获得适当的小时数。
string result = (int)elapsedTime.TotalHours + ":" + elapsedTime.Minutes + ":" + elapsedTime.Seconds
如果您可以考虑以天数格式显示结果,则可以使用TimeSpan格式:
elapsedTime.ToString("dd\.hh\:mm\:ss")
您可以阅读有关自定义TimeSpan格式here
