C# - converting from an exact number of seconds to DateTime : Newbie here! I have almost completed my given problem - got a total number of seconds. Now I need to print those seconds to a d:HH:mm:ss format. Like I mentioned, I'm kind of new, so it's kind of confusing. I tried the following:

    double totalSeconds = filteredPictures + totalFilterTime + totalUploadTime;
                string output = totalSeconds.ToString($"{total:dd.HH:mm:ss}");
                Console.WriteLine(output);

What am I doing that's not quite right?
