Question

I am trying to access COM object from on the fly compiled C# code.

It’s impossible to add assembly reference and “use” it by regular way, can anybody point me to dynamical COM query example?

Answer 1

You can use System.Activator to load the COM object on the fly, for example:

Type t = Type.GetTypeFromProgID("CDO.Message");
object obj = Activator.CreateInstance(t);

And use Type.InvokeMember() to call the methods of the object.
