c# - How do I choose the implementation of a type been registered with Microsoft Unity -

say have interface named ipumaservices, , have 2 classes implement it: posixmlservices , taxmlservices.

now have interface called ipumanotification , class implementing called pumanotification. constructor of pumanotification receives ipumaservices implementation.

my question: in unity, how can register implementation of pumanotification injects posixmlservices in contructor , injects taxmlservices?

this have far.

using (_unitycontainer = new unitycontainer())             {               _unitycontainer               .registertype<ipumaservices, posixmlservices>("posixml")               .registertype<ipumaservices, taxmlservices>("taxml")               .registertype<ipumanotification, pumanotification>();             } 

i have not idea how make work requirements have above.

i not able research online issue not sure how describe issue facing.

i appreciate help.

you can specify resolved parameters constructor , resolve instance want:

using (_unitycontainer = new unitycontainer())         {           _unitycontainer           .registertype<ipumaservices, posixmlservices>("posixml")           .registertype<ipumaservices, taxmlservices>("taxml")           .registertype<ipumanotification, pumanotification>(               new injectionconstructor(                        // explicitly specify constructor                  new resolvedparameter<ipumaservices>("taxml") // resolve parameter of type                );         } 

if want register 2 ipumaservices, can name each 1 appropriately , resolve name when use them.
