c# - How to coerce using direct class structuremap -

i have problem writing valid configuration classes. suppose have:

interface ia{}  class abstract : ia {}  class a1 : a, ia {     private readonly ib _ib;      public a1(ib ib)     {         _ib = ib;     } }  class a2 : a, ia {     private readonly ib _ib;      public a1(ib ib)     {         _ib = ib;     } } 

and want inject classes constructor of others, , think there have no problems that, doing this:

for<ienumerable<ia>>.use(x => x.allinstances<a>()); 

but don't know resolve problem property ib, if want use different _ib class a1 , class a2.

interface b{}  class b1 : b {}  class b2 : b {} 

i know if have 1 class b , class can this:

for<ia>().use<asample>().ctor<ib>().is<bsample>(); 

but problem try use this:

for<ia>().conditionallyuse(c => { c.if(t => t.concretetype == typeof(a1)) .thenit .is.constructedby(by => new a1(by.instanceof<b1>()));     c.if(t => t.concretetype == typeof(a1)) .thenit .is.constructedby(by => new a2(by.instanceof<b2>())); }); 

but gives me error of bidirectional registration..

or maybe should think this:

for<ienumerable<ia>>.use(x => x.allinstances<a>()); for<ienumerable<ib>>.use(x => x.allinstances<b>()); 

but variant should create abstract class, , additional method use 1 injected property list (for classes inherit interface b).

if me appreciate!

resolution problem write that:

for<ia>().add<a1>().ctor<ib>().is<b1>(); for<ia>().add<a2>().ctor<ib>().is<b2>();  //and for<ienumerable<ia>>.use(x => x.getallinstances<ia>());
