I'm trying to read a log file of log4net:
我正在尝试读取 log4net 的日志文件：
FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read)
and I get the Exception specified on the topic. I guess log4Net is holdin an exclusive lock on the file, but, as for example Notepad++ can read the file, I guess is technically possible to do this.
我得到了该主题指定的异常。我猜 log4Net 对文件持有独占锁，但是，例如 Notepad++ 可以读取文件，我猜在技术上可以做到这一点。
Any help?
有什么帮助吗？

using (FileStream fs =
new FileStream(filePath,
FileMode.Open, FileAccess.Read, FileShare.ReadWrite))

Your log may be write locked, so try with FileShare.ReadWrite.
您的日志可能被写锁定，因此请尝试使用 FileShare.ReadWrite。

Try to add the FileShare option, see if that helps:
尝试添加 FileShare 选项，看看是否有帮助：
FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
EDIT: corrected code, not FileShare.Readbut FileShare.ReadWritedoes the trick (as Guillaume showed as well). The reason: you want to open your file and allow others to read and write it at the same time.
编辑：更正的代码，FileShare.Read但不是FileShare.ReadWrite诀窍（正如纪尧姆所展示的那样）。原因：您想打开您的文件并允许其他人同时读取和写入它。
