How do I convert a TimeSpan to a formatted string? [duplicate]
Question
This question already has an answer here:
I have two DateTime vars, beginTime and endTime. I have gotten the difference of them by doing the following:
TimeSpan dateDifference = endTime.Subtract(beginTime);
How can I now return a string of this in hh hrs, mm mins, ss secs format using C#.
If the difference was 00:06:32.4458750
It should return this 00 hrs, 06 mins, 32 secs
Solution
Would TimeSpan.ToString() do the trick for you? If not, it looks like the code sample on that page describes how to do custom formatting of a TimeSpan
object.
OTHER TIPS
I just built a few TimeSpan Extension methods. Thought I could share:
public static string ToReadableAgeString(this TimeSpan span)
{
return string.Format("{0:0}", span.Days / 365.25);
}
public static string ToReadableString(this TimeSpan span)
{
string formatted = string.Format("{0}{1}{2}{3}",
span.Duration().Days > 0 ? string.Format("{0:0} day{1}, ", span.Days, span.Days == 1 ? String.Empty : "s") : string.Empty,
span.Duration().Hours > 0 ? string.Format("{0:0} hour{1}, ", span.Hours, span.Hours == 1 ? String.Empty : "s") : string.Empty,
span.Duration().Minutes > 0 ? string.Format("{0:0} minute{1}, ", span.Minutes, span.Minutes == 1 ? String.Empty : "s") : string.Empty,
span.Duration().Seconds > 0 ? string.Format("{0:0} second{1}", span.Seconds, span.Seconds == 1 ? String.Empty : "s") : string.Empty);
if (formatted.EndsWith(", ")) formatted = formatted.Substring(0, formatted.Length - 2);
if (string.IsNullOrEmpty(formatted)) formatted = "0 seconds";
return formatted;
}
By converting it to a datetime, you can get localized formats:
new DateTime(timeSpan.Ticks).ToString("HH:mm");
This is the shortest solution.
timeSpan.ToString(@"hh\:mm");
Use String.Format() with multiple parameters.
using System;
namespace TimeSpanFormat
{
class Program
{
static void Main(string[] args)
{
TimeSpan dateDifference = new TimeSpan(0, 0, 6, 32, 445);
string formattedTimeSpan = string.Format("{0:D2} hrs, {1:D2} mins, {2:D2} secs", dateDifference.Hours, dateDifference.Minutes, dateDifference.Seconds);
Console.WriteLine(formattedTimeSpan);
}
}
}
The easiest way to format a TimeSpan
is to add it to a DateTime
and format that:
string formatted = (DateTime.Today + dateDifference).ToString("HH 'hrs' mm 'mins' ss 'secs'");
This works as long as the time difference is not more than 24 hours.
The Today
property returns a DateTime
value where the time component is zero, so the time component of the result is the TimeSpan
value.
public static class TimeSpanFormattingExtensions
{
public static string ToReadableString(this TimeSpan span)
{
return string.Join(", ", span.GetReadableStringElements()
.Where(str => !string.IsNullOrWhiteSpace(str)));
}
private static IEnumerable<string> GetReadableStringElements(this TimeSpan span)
{
yield return GetDaysString((int)Math.Floor(span.TotalDays));
yield return GetHoursString(span.Hours);
yield return GetMinutesString(span.Minutes);
yield return GetSecondsString(span.Seconds);
}
private static string GetDaysString(int days)
{
if (days == 0)
return string.Empty;
if (days == 1)
return "1 day";
return string.Format("{0:0} days", days);
}
private static string GetHoursString(int hours)
{
if (hours == 0)
return string.Empty;
if (hours == 1)
return "1 hour";
return string.Format("{0:0} hours", hours);
}
private static string GetMinutesString(int minutes)
{
if (minutes == 0)
return string.Empty;
if (minutes == 1)
return "1 minute";
return string.Format("{0:0} minutes", minutes);
}
private static string GetSecondsString(int seconds)
{
if (seconds == 0)
return string.Empty;
if (seconds == 1)
return "1 second";
return string.Format("{0:0} seconds", seconds);
}
}
According to the Microsoft documentation, the TimeSpan structure exposes Hours, Minutes, Seconds, and Milliseconds as integer members. Maybe you want something like:
dateDifference.Hours.ToString() + " hrs, " + dateDifference.Minutes.ToString() + " mins, " + dateDifference.Seconds.ToString() + " secs"
You can use the following code.
public static class TimeSpanExtensions
{
public static String Verbose(this TimeSpan timeSpan)
{
var hours = timeSpan.Hours;
var minutes = timeSpan.Minutes;
if (hours > 0) return String.Format("{0} hours {1} minutes", hours, minutes);
return String.Format("{0} minutes", minutes);
}
}
Thanks to Peter for the extension method. I modified it to work with longer time spans better:
namespace ExtensionMethods
{
public static class TimeSpanExtensionMethods
{
public static string ToReadableString(this TimeSpan span)
{
string formatted = string.Format("{0}{1}{2}",
(span.Days / 7) > 0 ? string.Format("{0:0} weeks, ", span.Days / 7) : string.Empty,
span.Days % 7 > 0 ? string.Format("{0:0} days, ", span.Days % 7) : string.Empty,
span.Hours > 0 ? string.Format("{0:0} hours, ", span.Hours) : string.Empty);
if (formatted.EndsWith(", ")) formatted = formatted.Substring(0, formatted.Length - 2);
return formatted;
}
}
}
I know this question is older but .Net 4 now has support for Custom TimeSpan formats.
Also I know it's been mentioned but it caught me out, converting Ticks to DateTime works but doesn't properly handle more than a 24 hour span.
new DateTime((DateTime.Now - DateTime.Now.AddHours(-25)).Ticks).ToString("HH:mm")
That will get you 01:00 not 25:00 as you might expect.
I also had a similar issue and came up with my own extension but it seems to be a bit different than everything else.
public static string TimeSpanToString(this TimeSpan timeSpan)
{
//if it's negative
if (timeSpan.Ticks < 0)
{
timeSpan = timeSpan - timeSpan - timeSpan;
if (timeSpan.Days != 0)
return string.Format("-{0}:{1}", timeSpan.Days.ToString("d"), new DateTime(timeSpan.Ticks).ToString("HH:mm:ss"));
else
return new DateTime(timeSpan.Ticks).ToString("-HH:mm:ss");
}
//if it has days
else if (timeSpan.Days != 0)
return string.Format("{0}:{1}", timeSpan.Days.ToString("d"), new DateTime(timeSpan.Ticks).ToString("HH:mm:ss"));
//otherwise return the time
else
return new DateTime(timeSpan.Ticks).ToString("HH:mm:ss");
}
I know this is a late answer but this works for me:
TimeSpan dateDifference = new TimeSpan(0,0,0, (int)endTime.Subtract(beginTime).TotalSeconds);
dateDifference should now exclude the parts smaller than a second. Works in .net 2.0 too.
