in the first email i'm doing this:
<code>
var ass = Assembly.Load(assemblyname);
var type = ass.GetType(typename);
Type openType = typeof(GenericReportDataRepository<>);
Type actualType = openType.MakeGenericType(new Type[] { type });
object obj = Activator.CreateInstance(actualType);
var genrepo = Container.Resolve<GenericReportDataRepository<obj>>();
</code>
with the intention of creating an instance of
GenericReportDataRepository<T> with the generic type being
instantiated on the fly.
the GenericReportDataRepository<T> class is explained in the following email.
that is the scenario.
initially i know the type parameter to pass to
GenericReportDataRepository only as a string.
considering i have the component registered using:
<code>
<component id="GenericReportDataRepository"
type="Ideal.Reporting.Domain.GenericReportDataRepository`1,
Ideal.Reporting.Domain"/>
</code>
is there any way to get one of these from the container - with the
type parameter being either instantiated by activator.createinstance
or by passing a string :
var repo = Container.Resolve("GenericReportDataRepository", "TypeParameter");
or something?
it's a bit hard to explain the whole thing without going into a
massive essay - let me know if that's not making sense.
