c# - Is it possible to represent non gregorian dates as DateTime in .NET? -

i'm having trouble representing persian (solar hijri calendar) dates datetime in c#, on days of particular months, example 31/04 in gregorian calendar such date meaningless: system.globalization.persiancalendar p = new system.globalization.persiancalendar(); datetime date = new datetime(2013,7,22); int year = p.getyear(date); int month = p.getmonth(date); int day = p.getdayofmonth(date); datetime d1 = new datetime(year, month, day); the above code result in argumentoutofrangeexception saying: year, month, , day parameters describe un-representable datetime. which expected. how can represent persian dates datetime s in .net taking accounts dates such 30/02 , 31/04? the above code result in argumentoutofrangeexception saying: year, month, , day parameters describe un-representable datetime. yes, because unless specify calendar, datetime arguments expected gregorian. can specify calendar though: datetime d1 = new datetime(year, month, day, p); note i...

javascript - Sum of elements, differences between code -

i have 2 pieces of code both calculating sum of elements of array: var sum = array.reduce(function(previousvalue, currentvalue) { return previousvalue + currentvalue; }, 0); or var sum = 0; array.foreach(function(e) { sum += e; }); are there differences between them beside different implementations? when better use one? besides personal style preference, there difference in actual performance. 2 perform however. if you're doing operation lot (or large arrays) consider using third way: var sum = 0; (l = array.length; l--; ) { sum += array[l]; } this way faster. check this performance test actual results. note: gain speed if cache array length. instead of doing this: for (var = 0; < array.length; i++) {...} do this: var l = array.length; (; l--; ) { ... } or this: for (l = array.length; l--;) { ... }
