What is the difference between AxInterop and Interop?
提问by Yaron Naveh
I've added an .ocx to the toolbox in VS. Two .dll's were created: Interop.NNN.dll, AxInterop.NNN.dll.
我在 VS 的工具箱中添加了一个 .ocx。创建了两个 .dll：Interop.NNN.dll、AxInterop.NNN.dll。
What is each one? Are they both required?
每一个是什么？两者都需要吗？

The AxFoo.dll assembly contains an automatically generated class that's derived from the System.Windows.Forms.AxHost control. It is pretty simple, it has methods, properties and events, the same ones you have available in the .ocx, that simply call the Foo.dll interop library.
AxFoo.dll 程序集包含一个从 System.Windows.Forms.AxHost 控件派生的自动生成的类。它非常简单，它具有方法、属性和事件，与您在 .ocx 中可用的相同，只需调用 Foo.dll 互操作库。
So, yes, you definitely need to deploy both assemblies.
所以，是的，您肯定需要部署这两个程序集。

Interop.xxx.dll and AxInterop.xxx.dll are runtime callable wrappers (RCW) for a referenced COM and an ActiveX dll respectively.
Interop.xxx.dll 和 AxInterop.xxx.dll 分别是引用的 COM 和 ActiveX dll 的运行时可调用包装器 (RCW)。
interop.xxx.dll is purely an automation (a COM dll) wrapper, enabling you to manipulate the object within the namespace of your application. AxInterop.xxx.dll is a control wrapper for a ActiveX control, which can be dragged onto the form.
interop.xxx.dll 纯粹是一个自动化（COM dll）包装器，使您能够操作应用程序命名空间内的对象。AxInterop.xxx.dll 是 ActiveX 控件的控件包装器，可以将其拖到窗体上。
