Question

我们正在使用SoftArtisans ExcelWriter打开和处理来自各种excel文件的数据。最近有一个文件开始给我们以下错误： An item with the same key has already been added.

我已尝试使用Excel修复选项来修复文件并提取数据，但修复后的文件和原始文件都会继续返回相同的错误。

Stack Trace，正如所承诺的那样：

System.ArgumentException was unhandled by user code
HResult=-2147024809
Message=An item with the same key has already been added.

Answer 1

听起来像你或SoftArtisan的代码中有一个System.Collections.Generic.Dictionary，其中有两个具有相同键的对象被添加。
