我按照"Retrieving the COM class factory for component.... error: 80070005 Access is denied." (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))的步骤进行操作，但还是会出错。

我想念什么？

您似乎正在尝试在服务器上使用Excel自动化。这是不受支持的用例。实际上，这已经被许多人尝试和失败了很多次，以至于目前答案是众所周知的-不要在服务器上自动化Office产品。永远期。这是Microsoft和开发人员社区的正式答案。研究可以将文档作为数据文件创建，读取或操作的工具，例如Open XML SDK。（如果您要使用Open XML SDK，我强烈建议您在downloading the SDK时也下载Productivity工具。）

异常调用Excel.Interop
