In .NET, when you pass an instance / interface of a class as a parameter, you pass a single object or a full vtable

Question

If you pass an interface or an instance of a class as a parameter, we pass many objects or a full vtable, because as soon as you call the method on the instance, it needs to overwrite vtable and call the corresponding right?
How it works?

You pass the link (by value). The exact representation of the link is implementation-specific, but in most cases it will be a pointer :)

btw, there is no such thing as "passing an interface to a parameter". You always pass a reference to an object that can implement any, one or several interfaces.
