SoftArtisans ExcelWriter在尝试打开xlsx文件时返回重复键错误

SoftArtisans ExcelWriter returning duplicate key error when attempting to open xlsx file

We are using the SoftArtisans ExcelWriter to open and process data from various excel files. One file has recently begun giving us the following error: An item with the same key has already been added.

I've attempted the Excel repair options for repairing the file and extracting the data, but both the repaired files and the original file continue to return the same error.

Stack Trace, as promised:

System.ArgumentException was unhandled by user code
Message=An item with the same key has already been added.

It sounds like somewhere in your or SoftArtisan's code there is a System.Collections.Generic.Dictionary, where two objects with the same key are being added.
