.net - Encoding.Unicode.GetString error when resolving encryption Byte() -

-

have been trying encrypt xml file string may transfer on service. transmission server server using symetric key compiled code.

i have been using aes sample msdn , converting byte arry , string so:

    ' encrypt string array of bytes.     dim encrypted byte() = crypto.encryptstring(original, _key, _iv)      dim encrypstr string = encoding.unicode.getstring(encrypted)     '''' >>> transmit...     dim posttrans byte() = encoding.unicode.getbytes(encrypstr)      ' decrypt bytes string.     dim roundtrip string = crypto.decryptstring(posttrans, _key, _iv)

without middle 2 line encrypt/decrypt works fine, middle 2 lines included either recieve badly formed xml document cannot parsed or "padding invalid , cannot removed" error.

is not method string encryption? works without converting byte() string ad back.

do not use encoding.getstring(), not work. use tobase64()

thanks henk holterman answer.

c# - Copy ObservableCollection to another ObservableCollection -

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...
