Include DLL in classic asp

Is it possibl开发者_如何学Goe to include a .net 3.5 framework DLL in classic asp?

You will need to expose this .NET assembly as a COM object. This could be done using the regasm.exe utility. For this the types that you need to use or the entire assembly must be decorated with the ComVisible attribute.

Then consume the COM object from classic ASP as you would with any normal COM object.

Yes, it's called creating a COM-Callable Wrapper.

Here is the MSDN Documentation

The link that pops up for the Code Project article in Google is, surprisingly, not the better one. You'll want to check out this one: Exposing .NET Components to COM It's the best. Complete step-by-step tutorial.

It's worth noting that in a former life I had to develop and support a .NET application which was exposed to some COM-based integrations - and simply slapping ComVisible on my classes was putting me in a world of hurt. Pay attention to the author's explanation of the Interface Types in that article... that article is a gem.

Excerpt:

Previously I was using AutoDual, however Heath Stewart[^] pointed out this was not the best method to use as it can create version-related problems in the long run. After reading a little more I changed the code to use ClassInterfaceType.None which forces our class to gain access only through our interface. This keeps everything viable during changes to the class in the future.
