windows phone 7 - WP7 Deserialize JSON -

i'm new c# , having problems below giving invalidcastexception on line addresses address = (addresses)serializer.readobject(e.result);:

namespace my_app {     [datacontract]     public class addresses     {         [datamember(name = "line1")]         public string line1         {             get;             set;         }         [datamember(name = "line2")]         public string line2         {             get;             set;         }         [datamember(name = "postcode")]         public string rpostcode         {             get;             set;         }         [datamember(name = "city")]         public string city         {             get;             set;         }         [datamember(name = "state")]         public string state         {             get;             set;         }         }       public partial class sim : phoneapplicationpage     {          public sim()         {              initializecomponent();         }          private void button_tap(object sender, system.windows.input.gestureeventargs e)         {                  var webclient = new webclient();                      webclient.openreadcompleted += onopenreadcompleted;                      webclient.openreadasync(new uri("http://www.myurl" urikind.absolute));          }       }      private void onopenreadcompleted(object sender, openreadcompletedeventargs e)     {             var serializer = new datacontractjsonserializer(typeof(addresses));             addresses address = (addresses)serializer.readobject(e.result);      }  } }

json:

[     {         "@type": "accountaddress",         "line1": " 1",         "line2": "norwich road",         "postcode": "nr1 1au",         "city": "norwich",         "state": "norfolk"     },     {         "@type": "accountaddress",         "line1": " 2",         "line2": "norwich road",         "postcode": "nr1 1au",         "city": "norwich",         "state": "norfolk"     },     {         "@type": "accountaddress",         "line1": " 3",         "line2": "norwich road",         "postcode": "nr1 1au",         "city": "norwich",         "state": "norfolk"     } ]

i need in suitable format use in listpicker object. appreciated.

problem here is, json has set of addresses , trying access 1 address. in other words, serializer returns list of addresses trying convert single addresses object.

so change code this,

list<addresses> addresslist = (list<addresses>)serializer.readobject(e.result);

and need list or collection bind listpicker.

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...
