How can I String.Format a TimeSpan object with a custom format in .NET?

What is the recommended way of formatting `TimeSpan` objects into a string with a custom format?

One way is to create a `DateTime` object and use it for formatting:

new DateTime(myTimeSpan.Ticks).ToString(myCustomFormat)

// or using String.Format:
String.Format("{0:HHmmss}", new DateTime(myTimeSpan.Ticks))

This is the way I know. I hope someone can suggest a better way.

Dim duration As New TimeSpan(1, 12, 23, 62)

DEBUG.WriteLine("Time of Travel: " + duration.ToString("dd\.hh\:mm\:ss"))

It works for Framework 4

You can also go with:

Dim ts As New TimeSpan(35, 21, 59, 59) '(11, 22, 30, 30) '
Dim TimeStr1 As String = String.Format("{0:c}", ts)
Dim TimeStr2 As String = New Date(ts.Ticks).ToString("dd.HH:mm:ss")

EDIT:

You can also look at [Strings.Format][1].

Dim ts As New TimeSpan(23, 30, 59)
Dim str As String = Strings.Format(New DateTime(ts.Ticks), "H:mm:ss")

For .NET 3.5 and lower you could use:

string.Format ("{0:00}:{1:00}:{2:00}",
(int)myTimeSpan.TotalHours,
myTimeSpan.Minutes,
myTimeSpan.Seconds);

Personally, I like this approach:

TimeSpan ts = ...;
string.Format("{0:%d}d {0:%h}h {0:%m}m {0:%s}s", ts);

You can make this as custom as you like with no problems:

string.Format("{0:%d}days {0:%h}hours {0:%m}min {0:%s}sec", ts);
string.Format("{0:%d}d {0:%h}h {0:%m}' {0:%s}''", ts);
