c# - Returning Azure Blob Stream directly from WCF service -

-

i looking return stream azure blob storage directly browser via wcf. have rest wcf service , looking have users download files via service while files stored in azure blob storage.

in question

returning azure blob wcf service stream - need close it?

it downloads entire file new stream first, there way give blob stream return stream wcf wcf acts more proxy stream?

my issue large files (> 10mb), not want download entire stream azure storage before can start returning user.

the reason doing way doing security checks on user before allow access file stored in azure blob storage, of files 1gb in size.

i have done similar wcf used authorize client (and check blob still exists , on). if ok wcf service returned url shared access signature - allowed client access stream directly storage. saving transaction costs of pulling blob wcf role , streaming there.

might work you?

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...
