如何将经典ASP响应对象传递给C＃DLL

Question

Can anyone tell me whether it is possible to pass the Response object from classic asp to a C# class library and if so how it is done.

I'm using C# 2010 express and JScript in ASP, but I'll take a VBScript answer.

Or if there is another way of outputting to the http context of the classic asp page from a dll, that'll also do.

I thinking that it can't be done as the System.Web.HttpResponse object doesn't seem to be available from a class library.

Thank you to those who responded. By way of a complete answer for anybody else that may have the same question, here is some sample code:

public string passObj(ASPTypeLibrary.Response r)
{
    r.Write("text from DLL");
    return "OK";
}

and on the classic asp side of things:

var x = Server.CreateObject("dllTest.test");
x.passObj(Response);

Answer 1

To access the classic ASP objects including Response, you can add a COM reference in your C# project to "Microsoft Active Server Pages Object Library".

You can then reference it from C# as:

ASPTypeLibrary.Response

Answer 2

The Response object is a COM object that supports IUnknown and IDispatch . Therefore, you can pass it to a method as an object and call the properties using reflection.

From looking on my own machine, the IReponse IID is {D97A6DA4-D5F5-4763-9BE5-60126DD39E43} Typelib UUID is {A79CBB28-1006-4227-BE61-CBEE2520C353} . If you open regedit and navigate to HKEY_CLASSES_ROOT\\TypeLib\\{A79CBB28-1006-4227-BE61-CBEE2520C353}\\2.0\\0\\win32 the default key will contain a path to the Typelib you can import to create the interop assembly.
