Question

I using StructureMap to create instances of ModuleData

I have many classes that inherit from ModuleData(class A,B,C…) and each of them get Config1 or Config2 in coustructor
In Registry(located in file1.cs) I scan all types of ModuleData.

In Get(lacated in file2.cs) I get the instance.

I want that when ObjectFactory creates Config1/Config2 while creating instance of ModuleData it will pass “param” to Config1/Config2 constructors.
How I can configure structuremap to do this?

P.S. Registry & Get methods are located in different files!!!
Thank you

public class Config1
{
     Config1(string param)
     {
     }
}
public class Config2
{
     Config2(string param)
     {
     }
}
//.....//
public class A : ModuleData
{
    A(Config1 c)
   {
   }
}
public class B : ModuleData
{
    A(Config2 c)
   {
   }
}
//....//
//located in file1.cs
public Registry()
{
     Scan(x =>
     {
          x.TheCallingAssembly();
          x.AddAllTypesOf<ModuleData>();
     });            
     ObjectFactory.Initialize(x =>
     {
             x.For<Config1>().Use<Config1>();
             x.For<Config2>().Use<Config2>();
     });
}    
//....//
//located in file2.cs
public ModuleData Get(object o)
{
    var module = o as PageModule;
    var t = Type.GetType(string.Format("{0}.{1},{2}", Settings.Namespace, module.Name, Settings.Assembly));
    return ObjectFactory.With("param").EqualTo(module.Parameters).GetInstance(t) as ModuleData;
}

I can’t think of a good way to do what you want, I think its a bit of a design problem… I think you would have to explain a bit more about why you need to do this for me to help you.

What is a page module? Why is your config objects dependent on it?

Based on your comment, I think what you need is a factory object that creates ModuleData objects for you. Since they are objects it does not make much sense to get them from the container. Think about using a data access technology like Entity Framework, it would not make sense to get those objects from the container. From what I can tell, this is a similar case.
