问题

I have variable that is come from wcf with http call to javascript is like "P18DT5H"

C#:

param.time = new TimeSpan(18, 5, 0, 0);

I want to convert hours and minutes? Should I use regular expression?

回答1:

You can use ParseExact:

string span = "P18DT5H";

IFormatProvider formatProvider = System.Globalization.CultureInfo.InvariantCulture;
TimeSpan timeSpan = TimeSpan.ParseExact(span, "'P'd'DT'h'H'", formatProvider);

int hours = (int)Math.Floor(timeSpan.TotalHours);
int minutes = (int)Math.Round(timeSpan.Subtract(new TimeSpan(hours, 0, 0)).TotalMinutes, 0, MidpointRounding.AwayFromZero);

Console.WriteLine("{0} hours, {1} minutes", hours, minutes);

It will return for your example with no minutes:

437 hours, 0 minutes
