Transforming the COM object from IHTMLDocument2.Script.InvokeMember() into a functional and valuable asset

Currently, I am tackling a coding task in C#.NET involving an Internet Explorer extension. The challenge lies in calling Javascript within the browser and extracting the return value from the call. Handling primitive types or arrays of primitive types is manageable, however, when the Javascript returns an object, it results in obtaining an opaque COM object.

I am seeking guidance on how to access the contents of this COM object efficiently, or if there exists a more effective approach to interact with IE from C#.NET?

Answer №1

After reading the comments on the InvokeMember documentation page, it becomes clear that if the return value is a javascript object, what you are actually receiving is a .NET Object wrapper around it. This means using reflection will be necessary to inspect/invoke the members of the underlying javascript object. The reason for this is simple - javascript being a dynamic language and C# not.
