c# - Autofac ordered list as parameter -

i have object takes ordered list (iorderedenumerable) of items order of items important.

public class orderedlistworker : ilistworker {     private orderedlistworker(iorderedenumerable<ilistitem> orderedlistitems)     {         foreach (var listitem in orderedlistitems)             listitem.dosomethingwhereordermatters();     } } 

i have multiple objects of type ilistitem.

how can register orderedlistworker autofac , ensure listitems in specifc order @ run time?

i see order isn't guaranteed in this post, i'm not sure how guarantee order.

i have solution, combination of iorderedenumerable, , resolveordered<tcomponent> solution post linked above.

using autofacextensions class:

public static class autofacextensions {     private const string orderstring = "withordertag";     private static int _ordercounter;      public static iregistrationbuilder<tlimit, tactivatordata, tregistrationstyle>         withorder<tlimit, tactivatordata, tregistrationstyle>(         iregistrationbuilder<tlimit, tactivatordata, tregistrationstyle> registrationbuilder)     {         return registrationbuilder.withmetadata(orderstring, interlocked.increment(ref _ordercounter));     }      public static iorderedenumerable<tcomponent> resolveordered<tcomponent>(this icomponentcontext context)     {         return             context.resolve<ienumerable<meta<tcomponent>>>()                    .orderby(m => m.metadata[orderstring])                    .select(m => m.value).orderby(c => true);     } } 

i can specify registrations follows:

builder.registertype<listitema>().as<ilistitem>().withorder(); builder.registertype<listitemb>().as<ilistitem>().withorder(); builder.registertype<orderedlistworker>()                    .as<ilistworker>()                    .withparameter(                        new resolvedparameter(                            (info, context) => true,                            (info, context) => context.resolveordered<ilistitem>()));
