[英]remove seconds from timespan using c#
I want to remove the seconds from timespan using c#我想使用 c# 从时间跨度中删除秒数
My code is here:我的代码在这里:
TimeSpan lateaftertime = new TimeSpan();
lateaftertime = lateafter - Convert.ToDateTime(intime) ;
It returns the value 00:10:00
它返回值
00:10:00
But i want the below output : 00:10
only not seconds field :00
.但我想要以下输出:
00:10
only not seconds field :00
。
Well you can simply do as那么你可以简单地做
string.Format("{0}:{1}", ts.Hours,ts.Minutes) // it would display 2:5
EDIT编辑
to get it properly formatted use使其正确格式化使用
string.Format("{0:00}:{1:00}", ts.Hours,ts.Minutes) // it should display 02:05
Note that a TimeSpan
does not have a format .请注意,
TimeSpan
没有格式。 It's stored in some internal representation which does not resemble 00:10:00
at all.它存储在一些完全不像
00:10:00
内部表示中。
The usual format hh:mm:ss
is only produced when the TimeSpan is converted into a String
, either explicitly or implicitly.通常的格式
hh:mm:ss
仅在 TimeSpan 显式或隐式转换为String
时产生。 Thus, the conversion is the point where you need to do something.因此,转换是您需要做某事的地方。 The code example in your question is "too early" -- at this point, the TimeSpan is still of type
TimeSpan
.您问题中的代码示例“为时过早”——此时, TimeSpan 仍然是
TimeSpan
类型。
To modify the conversion to String, you can either use String.Format
, as suggested in V4Vendetta's answer, or you can use a custom format string for TimeSpan.ToString (available with .NET 4):要修改到 String 的转换,您可以使用
String.Format
,如 V4Vendetta 的答案中所建议的,或者您可以使用TimeSpan.ToString的自定义格式字符串(可用于 .NET 4):
string formattedTimespan = ts.ToString("hh\\:mm");
Note that this format string has the following drawbacks:请注意,此格式字符串具有以下缺点:
If the TimeSpan spans more than 24 hours, it will only display the number of whole hours in the time interval that aren't part of a full day.如果 TimeSpan 跨度超过 24 小时,它只会显示时间间隔中不属于一整天的小时数。
Example: new TimeSpan(26, 0, 0).ToString("hh\\\\:mm")
yields 02:00
.示例:
new TimeSpan(26, 0, 0).ToString("hh\\\\:mm")
产生02:00
。 This can be fixed by adding the d
custom format specifier .这可以通过添加
d
自定义格式说明符来解决。
Custom TimeSpan format specifiers don't support including a sign symbol, so you won't be able to differentiate between negative and positive time intervals.自定义 TimeSpan 格式说明符不支持包含符号符号,因此您将无法区分负时间间隔和正时间间隔。
Example: new TimeSpan(-2, 0, 0).ToString("hh\\\\:mm")
yields 02:00
.示例:
new TimeSpan(-2, 0, 0).ToString("hh\\\\:mm")
产生02:00
。
TimeSpan newTimeSpan = new TimeSpan(timeSpan.Hours, timeSpan.Minutes, 0);
Since there can be more than hours and minutes in a timespan string representation, the most reliable code for removing just the seconds and nothing else would be something like this:由于时间跨度字符串表示中可能有多个小时和分钟,因此最可靠的代码只删除秒而不是其他任何内容,如下所示:
var text = TimeSpan.FromDays(100).ToString(); // "100.00:00:00"
var index = text.LastIndexOf(':');
text = text.Substring(0, index); // "100.00:00"
