c# - List<string[]> displaying list values -

-

i have code generates list<string[]> variable can't quite figure out how display in text box properly. 

list<string[]> test = parsecsv(); (int = 0;  < test.count; i++) {   console.writeline("i = {0}",i);   console.writeline("test[i] = {0}", test[i]);   namelist.text = test[i].tostring() + "\n" + namelist.text; }

when output test[i] console displays string information correctly, when output test[i] text box get:

system.string[] system.string[] system.string[] system.string[] system.string[] system.string[]

can tell me i'm doing wrong?

this common misconception tostring shows in variety of situations. not magical formatting wizard, if primitive types appear work "as expect". tostring provides reasonable representation of data @ hand.

in case of array data, obnoxious , incorrect .net output entire array every tostring call (which debugger makes heavy usage of). imagine 3d array of strings 60x60x10. hate have wait on rendered because put mouse on array in debugger.

in case use string.join:

for (int = 0;  < test.count; i++) {     console.writeline("i = {0}",i);     console.writeline("test[i] = {0}", test[i]);     namelist.text = string.join(", ", test[i]) + "\n" + namelist.text; }

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...
