Hello,

I'm walking the CodeElements collection in a solutions DTE.Projects
collection and I'm trying to find more information about method
parameters... namely I need to know what type it is but the CodeElement
object doesn't have much in there. For example, take the following
method:

void MyMethod(MyClass & aClass);

Somewhere deep in the tree would be an element where .Kind equals
vsCMElementFunction and it would have one child whose .Kind is
vsCMElementParameter named "aClass" but no where, can I find that it is
of type MyClass.

Does anyone know how to get that information? Thanks!
Alex

Once you have a CodeElement of vsCMElementParameter kind, cast it to
EnvDTE.CodeParameter and check its CodeParameter.Type property, which
returns an EnvDTE.CodeTypeRef and check its properties.

Ok, so the CodeParameter.Type gives me the string of the type in
question but is there any way I can get back to the actual CodeElement
that represents the definition of that type?

Thanks,
Alex

That's a tough question, because the actual type can be:

- A type declared somewhere in your project. In this case you must use
Project.CodeModel.CodeElements, etc. to locate it.
- A type declared somewhere in a referenced project. In this case you must
use CType(Project.Object, VSProject).References, get the
Reference.SourceProject property and use again
Project.CodeModel.CodeElements-
- A type declared somewhere in a referenced assembly. In this case you must
use Reflection to find it, the GetExportedTypes function.

That's awesome. That's exactly what I need. Although, is a string
name match the strongest relationship one can glean? I guess since
they are identifiers and as long as namespaces are processed properly
it had better be unique.

Thanks!
Alex
