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

Question

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

Answer 1

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.
