I have some strings of xxh:yym format where xx is hours and yy is minutes like "05h:30m". What is an elegant way to convert a string of this type to TimeSpan?
This seems to work, though it is a bit hackish:
TimeSpan span;
if (TimeSpan.TryParse("05h:30m".Replace("m","").Replace("h",""), out span))
MessageBox.Show(span.ToString());
Are TimeSpan.Parse and TimeSpan.TryParse not options? If you aren't using an "approved" format, you'll need to do the parsing manually. I'd probably capture your two integer values in a regular expression, and then try to parse them into integers, from there you can create a new TimeSpan with its constructor.
DateTime.ParseExact or DateTime.TryParseExact lets you specify the exact format of the input. After you get the DateTime, you can grab the DateTime.TimeOfDay which is a TimeSpan.
In the absence of TimeSpan.TryParseExact, I think an 'elegant' solution is out of the mix.
@buyutec As you suspected, this method would not work if the time spans have more than 24 hours.
Here'e one possibility:
TimeSpan.Parse(s.Remove(2, 1).Remove(5, 1));
And if you want to make it more elegant in your code, use an extension method:
public static TimeSpan ToTimeSpan(this string s)
{
TimeSpan t = TimeSpan.Parse(s.Remove(2, 1).Remove(5, 1));
return t;
}
Then you can do
"05h:30m".ToTimeSpan();
@John:
It is a nice method but what if the input is "26h:30m"?
