推荐答案

如果某个进程访问了某个资源，那么它将拥有一个锁。在这种情况下，没有其他进程可以访问资源。因此，请确保在访问该文件时没有其他进程正在访问该文件。没有办法解决这个问题。要么你必须杀死正在使用该文件的进程，要么保留它。在您的情况下，制作文件的副本并使用它。处理完成后，有2份文件和删除。

If a resource is accessed by a process then it will have a lock.So no other process can access the resource in this case. So make sure when you access the file no other processes are accessing the file. There is no way to fix this issue. Either you have to kill the process which is using the file or leave it like that. In your case make a copy of the file and use it. have 2 copies of file and delete once the processing is done.
