c# - REST webservice WebAPI - create endpoint based on multiple entities -

i have need create rest webservice. followed tutorial: http://www.odata.org/blog/how-to-use-web-api-odata-to-build-an-odata-v4-service-without-entity-framework/

everything worked fine, added basicauth it, works glove.

now, question... webservice work possible versions of it, decided implement sort of versions systems. also, want client applications choose database want perform actions. that, thought nice have uris style:

http://localhost/connection/northwind/api/1/datarow

this code have. used have entity datarow defined. have defined entity api , connection.

how implement uri/endpoint want? code have, far.

you can config api versioning global route prefixes attribute routing... can create class inherits defaultdirectrouteprovider 1 below

public class centralizedprefixprovider : defaultdirectrouteprovider {     private readonly string _centralizedprefix;      public centralizedprefixprovider(string centralizedprefix)     {         _centralizedprefix = centralizedprefix;     }      protected override string getrouteprefix(httpcontrollerdescriptor controllerdescriptor)     {         var existingprefix = base.getrouteprefix(controllerdescriptor);         if (existingprefix == null) return _centralizedprefix;          return string.format("{0}/{1}", _centralizedprefix, existingprefix);     } } 

and add in webapiconfig.cs this

config.maphttpattributeroutes(new centralizedprefixprovider("api/v{version:int}"));
