How to format TimeSpan.ToString in .NET 4.0

Question

Hello, I'm trying to format my TimeSpan string using

 myString = myTimeSpan.ToString("c");

However the TimeSpan.ToString method does not take a format string as an argument until .NET 4.0 while Unity's version of Mono is still on 3.5.

How would you format DateTime and TimeSpan strings then?

myString = string.Format("{0:c}", myTimeSpan);

Thank you! However this solution works only for formatting DateTime.

In the case of TimeSpan, even if the format string is changed such as

myString = string.Format("{0:%s}", myTimeSpan);

which should only output the value of the myTimeSpan.Seconds property, myTimeSpan is still displayed with the default format string "c", showing dd:hh:mm:ss:fffffff.

So it doesn't seem to work for formatting TimeSpan.

So what format are you after? Something like this:

   myString = string.Format("{0:00}:{1:00}", myTimeSpan.$$anonymous$$inutes, myTimeSpan.Seconds);

Yes! This is what I was looking for!

I had been using a workaround as such:

myString = string.Format("{0:HH\\:mm\\:ss}", new DateTime(myTimeSpan.Ticks));

but your solution is much more correct, thank you.

Stackoverflow is a great resource, but I personally find that Unity-centric questions get better answers here. Also this question is for an older version of C# and Stackoverflow tends to focus on the latest specification from my experience.
