How Do I Convert Seconds to a Formatted Time Duration (hh:mm:ss:fff) in .NET?

Converting Seconds to Time Duration

In .NET, you can convert seconds into a formatted time duration, such as "00h:00m:00s:00ms." Here's how you can achieve this:

For .NET <= 4.0:

The TimeSpan class provides a convenient way to represent time durations. To convert seconds into a TimeSpan object:

TimeSpan t = TimeSpan.FromSeconds(seconds);

To format the TimeSpan in the desired format, use the "string.Format" method:

string answer = string.Format("{0:D2}h:{1:D2}m:{2:D2}s:{3:D3}ms", 
                t.Hours, 
                t.Minutes, 
                t.Seconds, 
                t.Milliseconds);

This will produce a formatted string with the specified placeholders filled with the corresponding values from the TimeSpan object.

For .NET > 4.0:

In .NET 4.0 and above, you can also use the ToString() method of TimeSpan with a custom format string to achieve the desired result:

TimeSpan time = TimeSpan.FromSeconds(seconds);

// Use backslash to escape the colon character
string str = time.ToString(@"hh\:mm\:ss\:fff");

Additional Note:

As mentioned in the provided answer, ensure that the input seconds value is less than the maximum allowed value for TimeSpan.MaxValue.TotalSeconds (approximately 24 days) to avoid an exception.
