c# - How to report standard exceptions to the user? -

-

consider c# gui application uses filestream read file, chosen user through "open file" dialog.

in case read fails one of exceptions, correct way report failure user, in user-friendly manner?

should invent own message each of exceptions, or there way of obtaining localized, user-friendly message present verbatim user?

edit

i'm asking whether .net able provide me descriptive string can present (and consistent other .net programs). know can roll own, i'd avoid if there's standard alternative.

you can have set of localizable user exceptions 1 of them being fileuploaderror. can put localized general information there. throwing few technical details might bit challenging, can quite hard right balance between technical details , simple step user needs take fix error.

my suggestion be:

  1. have 1 user level fileuploaderrorexception
  2. have details property in it
  3. depending on actual exception, suggest user try few things

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
