C # Excel (opening part)

I believe that many people need to make a lot of reports during system development. CMS and GIS may not encounter such problems in processing complicated Excel and generating complicated EXCEL reports, however, when I was working on ERP, sap, and other software systems related to production and office work, I certainly had to deal with these problems. I encountered similar thorny problems for some time last year, C # is easy to learn, but it is basically a starting point. I am exploring and learning how C # operates COM components, in the next chapter, I will introduce how C # operates excel, how to generate complex reports, and how to generate a colorful chart of Excel, MES development personnel are helpful and hope you will pay attention to them.
