Hi there,

I have time-of-day spans presented as strings and want to check, if, at
a given time, I am within such a time span.

Example: Timespan-string is given as follows: "09:00 , 16:00"

A function should now return true if the current time of day is between
9:00 and 16:00 and false otherwise.

Any help is appreciated. The problem sounds trivial, yet I currently
fail to come up with a pleasant solution.

cheers,

Mathias

string t = "09:00 , 16:00";

string start = t.Substring(0, 5), end = t.Substring(8, 5);
string now = DateTime.Now.ToString("HH:mm");

return (now >= start && now <= end);

Eq.

It is fairly trivial: just parse out the actual TimeSpans you want out of
timespan-string so that you have two strings: one containing "09:00" and another
containing "16:00". Create TimeSpans with them them (TimeSpan.Parse), and return
whether DateTime.Now.TimeOfDay is between them.

Chris.
