this question has answer here:

i trying write months array in order.

                                string january = "january";                                 string february = "february";                                 string march = "march";                                 string april = "april";                                 string may = "may";                                 string june = "june";                                 string july = "july";                                 string august = "august";                                 string september = "september";                                 string october = "october";                                 string november = "november";                                 string december = "december";

and writing array so:

                            (int = 0; < (janc - 1); i++)                                 {                                     analyser.sortedmonths[i] = january;                                 }

sortedmonths initialized in cs sheet. sorted months array 1022 in size amount of months being read in.

why not working? have googled null reference exception have not found related writing array.

analyzer.sortedmonths null. have initialize it:

analyzer.sortedmonths = new string[12];

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
