c# - SharePoint 2010“错误”打开通过 C# 创建的 Excel

Answer 1

Thanks to this article I found the problem. With the OpenXmlValidator class you can easily find errors in a created file. In my case the problem was that the title/name of one of my sheets was longer than 31 characters and 31 seems to be the limit. Problem solved, so for anyone with a similar issue, I strongly recommend the use of the validator! ;)
