如果采用托管代码做封装的话，可以通过此示例中的方法进行调用

COM Registration of the Libraries
What is great with managed platforms like Java and .NET is that once you have your byte-code binaries, you can use a single process to rule them all. So here are the COM-registration commands for the 3 implementations of the API (you’ll need to run them with administrator privileges):

Collapse | Copy Code
regasm /codebase /tlb FinanceCS.dll
...
regasm /codebase /tlb FinanceVBNet.dll
...
regasm /codebase /tlb FinanceCPP.dll
...
Some explanations:

“/codebase” tells regasm to reference the assemblies full path into the registry, not only its name; otherwise your assembly should be put into the GAC which in this case is useless and would be pure over-engineering (but sometimes, for assemblies shared by many applications, the GAC can be useful)
“/tlb” tells regasm to generate and register a TLB file for the DLLs: a TLB file holds some metadata that will be consumed by the clients of our API to allow for a more user-friendly usage especially by allowing auto-completion in the VBA editor.
Our API is now ready to get used by VBA.

Regasm.exe（程序集注册工具）说明

/codebase
在注册表中创建一个 Codebase 项。 Codebase 项指定未安装到全局程序集缓存中的程序集的文件路径。 如果随后要安装正在注册到全局程序集缓存中的程序集，则不应指定此选项。 用 /codebase 选项指定的 assemblyFile 参数必须是具有强名称的程序集。

/tlb [:typeLibFile]
从指定的程序集生成类型库，该类型库包含在程序集中定义的可访问类型的定义。
