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
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.
ToString method can take a custom format as an argument (like mm\\:ss), according to this page : msdn.microsoft.com/en-us/library/dd992632.aspx –
Battement 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;
}
extensible :( but it is certainly the correct direction, you should accept a string like "hh:mm" in here and build the time based on that. Just like ToString() I think the answer by @rubenroid is the best answer. –
Affectional TimeSpan like "2 days ago" or "15 minutes ago" then check this gist inspired by @Marisolmarissa anwear: gist.github.com/Rychu-Pawel/fefb89e21b764e97e4993ff517ff0129 –
Trammell By converting it to a datetime, you can get localized formats:
new DateTime(timeSpan.Ticks).ToString("HH:mm");
1. –
Provitamin This is the shortest solution.
timeSpan.ToString(@"hh\:mm");
timeSpan.ToString("hh\\:mm"); –

Battement 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);
}
}
}
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);
}
}
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.
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"
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;
}
}
}
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);
}
}
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");
}
timeSpan = timeSpan - timeSpan - timeSpan; as different is an insult to different :-) but I like it, in a perverse sort of way –
Cimbri 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 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.
