推荐答案

xlsx搜索规范应该是* .xlsx。



另外，你的MyDocuments路径中有一个文件夹这对你来说是禁区。您启动的代码始终以您的身份运行，因此它具有您所执行的完全相同的权限。例如，您无法搜索路径C：\

That "xlsx" search spec should be "*.xlsx".

Also, you've got a folder in your MyDocuments path somewhere that is off-limits to you. The code you launch always runs as you so it has the exact same permissions you do. For example, you can't search the path "C:\

Recycle.Bin\S-1-5-18。尝试这样做会导致你得到的错误。



要么不搜索AllDirectories，要么编写自己的搜索来处理异常和继续前进，忽略失败的文件夹路径。这并不难。

Recycle.Bin\S-1-5-18". Attempting to do so will result in the error you're getting.

Either don't search "AllDirectories", or you write your own search that handles the exception and keeps going, ignoring the folder paths that fail. It's not that hard.
