Using C# Selenium, how would I read/write data from an Excel file that is already open on the user's machine?使用 C# Selenium，我将如何从用户机器上已经打开的 Excel 文件中读取/写入数据？ I've searched the other answers here and only see how to open the Excel and start reading.我在这里搜索了其他答案，只看到如何打开 Excel 并开始阅读。 Am I able to connect to a file that is already open and read/write to it?我是否能够连接到已打开的文件并对其进行读/写？ In my case I would know the exact file name just not the file location.就我而言，我会知道确切的文件名而不是文件位置。

If you open your File-Explorer and go into the Folder of the Excel-File you will see a lock-File when one other user has opened the Document.如果您打开文件资源管理器并进入 Excel 文件的文件夹，当其他用户打开文档时，您将看到一个锁定文件。 This will be on all Office Documents.这将出现在所有 Office 文档上。

In normal mode only one (the first) User can open a Office Document and write in it.在正常模式下，只有一个（第一个）用户可以打开 Office 文档并在其中写入。 So no other User can write ...所以没有其他用户可以写......

But there will be a Function that allowes multiple-Users to work in the same time on one Office Document.但是会有一个功能允许多个用户同时在一个 Office 文档上工作。 So multiple User can open and do changes over the day.因此，多个用户可以在一天内打开并进行更改。 It will update for a single User directly on save with the modifications from the other Users.它将在保存时直接更新单个用户，并使用其他用户的修改。

I dont know the english name of this function, but it should be something like -Approve Document-我不知道这个函数的英文名称，但它应该类似于 -Approve Document-
