Question

This is my input:

55

This is my desired output:

PT55H

Is there a built in class in C# that converts a timespan as: TimeSpan.TryParse(55) or as a string “55” with hours into an ISO8601 formatted string?

Answer 1

Coworker just found this for me:

TimeSpan start = new TimeSpan(int.Parse(txtStartHours.Text), 0, 0); 
durationNode.Element("StartTime").Value = XmlConvert.ToString(start); 

It seems to convert it to PT2D7H, but since I’m using XMLConvert.ToTimeSpan().TotalHours elsewhere, it shouldn’t cause any problems!
