TypeInfo_Interface from runtime string?

[Thalamus via Digitalmars-d-learn]

Hi everyone,

My project includes lots of .Net interop via C linkage. One of 
the things I need to do is refer in C# to an interface declared 
in the D code, and then to actually work with the interface 
concretely in the D layer. So, I need to get a TypeInfo_Interface 
object from a string passed in from C#.

The problem isn't in marshaling the string between C# and D, but 
rather what to do with the string once I have it in D.

So in the D code, where interfaceName is the fully qualified name 
of an interface, e.g.  "MyPackage.MyModule.MyInterface", what I 
would like is something like:


TypeInfo_Interface theInterface = new 
TypeInfo_Interface(interfaceName);


But there's no such constructor.

Apologies if this seems like it should be obvious, but I couldn't 
find anything in the forums or the wider web. :)

thanks,
Thalamus
