Question

I have multiple implementations of the same interface who all have the same constructor parameter (strConn). Is it possible to register all implementations with 1 container.Register call?

Here is what I have:

container.Register(
            Classes.FromAssemblyContaining<IUserMenuDao>()
                .BasedOn<IDataAccess>().WithService.FromInterface()
            );

These implementations all have the same constructor parameter; strConn. Registering one would be:

container.Register(Component.For<IUserMenuDao>()
                               .DependsOn(new {strConn = ConfigurationManager.ConnectionStrings["ABC123"].ConnectionString})
                               .ImplementedBy<UserMenuDaoSqlServerImpl>());

Is there a way to register by convention similar to code sample #1 but using a DependsOn for all implementations?

Answer 1

Yes Indeed

container.Register( 
    Classes.FromAssemblyContaining<IUserMenuDao>() 
         .BasedOn<IDataAccess>()
         .WithService.FromInterface() 
         .Configure(c => c.DependsOn(new {strConn = ConfigurationManager.ConnectionStrings["ABC123"].ConnectionString}))
    );
