关于c＃：如何将TimeSpan转换为格式化字符串？


How do I convert a TimeSpan to a formatted string?

本问题已经有最佳答案，请猛点这里访问。

我有两个日期时间变量，begintime和endtime。我通过以下操作得到了它们的区别：

1
TimeSpan dateDifference = endTime.Subtract(beginTime);

我现在如何使用c_返回hh-hrs、mm-mins、ss-secs格式的字符串？

如果差是00:06:32.4458750

它应该返回这个00小时06分32秒

它被转换到的日期时间格式的定，你可以得到：

1
new DateTime(timeSpan.Ticks).ToString("HH:mm");
相关讨论

这是最短的解决方案。

1
timeSpan.ToString(@"hh\:mm");

(3)将timespan.tostring的你吗？如果不是，它看起来像这样的代码示例，介绍如何在页面的自定义格式的TimeSpan对象。

使用string.format(多参数)。

在easiest路TimeSpan格式它是添加到DateTime和格式是：

1
string formatted = (DateTime.Today + dateDifference).ToString("HH 'hrs' mm 'mins' ss 'secs'");

本厂是一长的时间差不超过24小时。

在TodayDateTime物业收益值在零时间的操作系统组件，组件的时间是TimeSpan的结果值。

根据微软的文档，在时间结构exposes小时，分钟，秒和milliseconds的成员。也许你想让这样的事情：

1
dateDifference.Hours.ToString() +" hrs," + dateDifference.Minutes.ToString() +" mins," + dateDifference.Seconds.ToString() +" secs"

你可以使用下面的代码。

我知道这是一个大问题，但是现在网上有4。支持自定义格式的时间。

我知道，但它引起了上述的被转换的DateTime蜱对我作品的推出，但不恰当的T手柄跨度超过24小时。

1
new DateTime((DateTime.Now - DateTime.Now.AddHours(-25)).Ticks).ToString("HH:mm")

这是不是你会得到1点25点，你可能期望。

我也有类似的问题和我自己扩展的凸轮跟踪位但它似乎是不同的比其他的事情。

我知道这是一晚，但我的答案是：这个作品

1
TimeSpan dateDifference = new TimeSpan(0,0,0, (int)endTime.Subtract(beginTime).TotalSeconds);

现在datedifference应该排除在较小的比第二部分。在.NET 2.0的作品了。
