TimeSpan to Custom string like HH:mm:ss [duplicate]

Question

I would like to convert

var delta = TimeSpan.FromSeconds(10);

to string like 00:00:01

I try this delta.ToString(@"0:\\hh\\:mm\\:ss", System.Globalization.CultureInfo.InvariantCulture);

But nothing is working fine. Also I cannot find here https://msdn.microsoft.com/en-us/library/ee372287.aspx correct way to do it.

Method ToString() does not help so i need in format lie hh:mm:ss.

Any clue?

Answer 1

Just use :

delta.ToString(); // 00:00:10

which does the trick for you (Fiddle)

Or try this:

var str = string.Format("{0:00}:{1:00}:{2:00}", delta.Hours, delta.Minutes, delta.Seconds);

You can build an extension method if you use it a lot:

public static class MyExtensions
{
    public static string ToCustomString(this TimeSpan span)
    {
        return string.Format("{0:00}:{1:00}:{2:00}", span.Hours, span.Minutes, span.Seconds);
    }
}

Usage:

string strSpan = delta.ToCustomString();
