c# - How to Convert plain text data into managed format? -

-

using c#, goal create working app accept text file input, read it, , separate sections of data within text file distinct groups contain index #, , name of section found in first part of section.

this perhaps more of question how take data in plain text file, separate sections of data "groups"? , output file in managed format.

the text input file has 13 fields, , additional field status, making 14 fields.

the text input file have 1500 - 2000 groups of sections of data, there 2000 entries indexed , name of entry being first field, "package name". section of data this:

package:  horse version:  1.2.3 depends:  libgcc provides: status:  user installed other:   other info other2:  other info 2  package:  cow version:  2.3.4 depends:  libhay provides: milk status:   user installed other:    white black spots other2:   has red cow bell around neck  package:  tractor version:  0.9.22 depends:  diesel provides:

etc...

how can data read , placed appropriate tables or entries or datasets?

ps previous edit

a simplistic solution read file 1 line @ time, splitting @ ":" , storing each in dictionary<string, string> stored in package , adding list<package>. whenever keyword "package", create new package instance , add list. code below trick, not defensively coded.

    static void main(string[] args)     {       string line;       list<package> packages = new list<package>();       package package = null;       streamreader file = new system.io.streamreader("textfile1.txt");       while ((line = file.readline()) != null)       {         string[] pair = line.split(new string[] { ": " }, stringsplitoptions.none);         if (pair.length != 2)           continue;         if (pair[0] == "package")         {           package = new package();           packages.add(package);         }         package.values.add(pair[0].trim(), pair[1].trim());       }       file.close();       console.writeline(packages.count);       foreach (package p in packages)       {         console.writeline(p);         foreach (keyvaluepair<string, string> pair in p.values)           console.writeline("{0}={1}", pair.key, pair.value);       }       console.readline();     }   }    class package   {     public dictionary<string, string> values;     public package()     {       values = new dictionary<string, string>();     }   }

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...
