Hi Krzysztof
Thanks for your fast response...
Regarding my App issue I was able to do some progress using that method you
mentioned:
---
IWindsorContainer container = new WindsorContainer();
AssemblyFilter filter = new
AssemblyFilter(System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location));
container.Kernel.Resolver.AddSubResolver(new
ArrayResolver(container.Kernel, true));
container.Register(
Classes.FromAssemblyInDirectory(filter).BasedOn<IOCApp02Interfaces.IFileDownloader>().WithServiceBase(),
Classes.FromAssemblyInDirectory(filter).BasedOn<IOCApp02Interfaces.ITitleScraper>().WithServiceBase()
);
container.Register(
Component.For<HtmlTitleRetriever>()
//.DependsOn(Dependency.OnComponentCollection<IOCApp02Interfaces.IFileDownloader[]>(
// "IOCApp02.HttpFileDownloader",
// "IOCApp02ExtendedLib.FtpFileDownloader",
// "IOCApp02ExtendedLib.FileSystemFileDownloader"))
.DependsOn(Dependency.OnValue("files", new Uri[] {
new
Uri("http://mi.mirror.garr.it/mirrors/postfix/index.html";),
new
Uri("ftp://mi.mirror.garr.it/mirrors/postfixweb/announcements.html";),
new
Uri("file:///C:/Users/jcarvalho/Documents/Work/vs2012/CastleWindsorIOCApp/IOCApp02/teste.txt")
}))
);
HtmlTitleRetriever retriever =
container.Resolve<HtmlTitleRetriever>();
---
If I dont use the ArrayResolver I was able to do the thing using the lines
in coments;
But how can I pass arguments needed for the contructor or inject properties
at the resolve moment (bold line) ?
About my process of looking for information: well ... for example: I would
like to see something like this <http://autofac.org/apidoc/> but with
realistic examples; for instance: reading this wiki
page<http://docs.castleproject.org/Windsor.Arguments.ashx> I
suspect that this is the answer to my question above but I still can not
figure how I can pass an IFileDownloader[] to my constructor on resolving
time...
... well at this time I opted to dig a little more before post my answer
and It seems I was able to to do what I wanted: the only problem is that
I'm not real sure if this is the right approach...?
---version 2:
IWindsorContainer container = new WindsorContainer();
IWindsorContainer container = new WindsorContainer();
AssemblyFilter filter = new
AssemblyFilter(System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location));
//container.Kernel.Resolver.AddSubResolver(new
ArrayResolver(container.Kernel, true));
container.Register(
Classes.FromAssemblyInDirectory(filter).BasedOn<IOCApp02Interfaces.IFileDownloader>().WithServiceBase(),
Classes.FromAssemblyInDirectory(filter).BasedOn<IOCApp02Interfaces.ITitleScraper>().WithServiceBase()
);
container.Register(
Component.For<HtmlTitleRetriever>()
);
IFileDownloader[] aDownloaders =
(IFileDownloader[])container.ResolveAll(typeof(IFileDownloader));
Uri[] thefiles = new Uri[] {
new
Uri("http://mi.mirror.garr.it/mirrors/postfix/index.html";),
new
Uri("ftp://mi.mirror.garr.it/mirrors/postfixweb/announcements.html";),
new
Uri("file:///C:/Users/jcarvalho/Documents/Work/vs2012/CastleWindsorIOCApp/IOCApp02/teste.txt")
};
HtmlTitleRetriever retriever =
container.Resolve<HtmlTitleRetriever>(new Arguments(new { downloaders =
aDownloaders, files = thefiles }));
---
note the comment line: I'm not even using the ArrayResolver method, I
suspect this is because we are passing the arguments so the container does
not need to resolve the IFileDownloader[] it just returns an Array that I
can cast to IFileDownloader[]
My problem with the wiki is that the learning curve is really slow, the
method turns out to be very much trial and error...
Yet another question, regarding the registration: what are the possible or
best methods for this situation: I have all my services (interfaces) in an
assembly, and the implementations separated for 2 assemblies: the running
one (app) and another one that is not referenced by anyone; is using
FromAssemblyInDirectory like I did is the best choice?
(These must be really windsor-newbie questions...)
Thank you again for your answer, it helped a lot...
