c# - Getting IConfiguration from ServiceCollection -

i´m writing own extension method servicecollection registered types of module , need access iconfiguration instance collection register options.

extension method

public static iservicecollection addapi(this iservicecollection services) {   // configuration collection   var configuration = (iconfiguration) services.firstordefault(p => p.servicetype == typeof(iconfiguration)).implementationinstance;    services.configure<databaseoptions>(configuration.getsection("database")); } 

is right way iconfiguration instance collection or there more elegant solution? not want add iconfiguration instance parameter method.

i created own "service collection" type wrapped iservicecollection , iconfiguration , modules use type register services. example:

public interface imyservicecollection {     public iservicecollection services { get; set; }      public iconfiguration configuration { get; set; } }  public static void addfoomodule(this imyservicecollection myservices) {     var services = myservices.services;     var config = myservices.configuration; } 

then have create extension method configuration instance parameter creates implementation imyservicecollection, such as:

public static imyservicecollection createservicecollection(this iservicecollection services, iconfiguration config) {     return new myservicecollection      {          services = services,         configuration = config     }; } 

note using in modular framework. simple applications overkill.

i think solution fine well. if need access iconfiguration instance might find searching in service collection on , on bit tedious.
