c# - Autofac two properties with the same type -

-

if i've got 2 properties in class same interface type , want inject 2 different conrete types each how do autofac either property or constructor injection.

eg.

class : ia {     public ib propertyb { get; set; }     public ib propertyc { get; set; }      public a(ib b, ib c)     {         propertyb = b;         propertyc = c;     }      public void printb()     {         propertyb.print();     }      public void printc()     {         propertyc.print();     } }

i've tried of course c inject both properties

    var builder = new containerbuilder();      builder.registertype<b>().as<ib>();     builder.registertype<c>().as<ib>();     builder.registertype<a>().as<ia>();      var container = builder.build();     var = container.resolve<ia>();

or same result:

    builder.registertype<b>().as<ib>();     builder.registertype<c>().as<ib>();     builder.registertype<a>().as<ia>().propertiesautowired();      var container = builder.build();     var = container.resolve<ia>();

is there way can tell autofac want b in propertyb , c in propertyc ?

using property injection, can following:

builder.registertype<a>()     .as<ia>()     .onactivating(e => {     e.instance.propertyb = e.context.resolve<bimpl1>();     e.instance.propertyc = e.context.resolve<bimpl2>(); });

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...
