在我的应用程序中，我有一些远程位置的文件说\\server\sharedfolder，程序根据用户操作执行MOVE或DELETE等操作，并将相应的文件移动到另一个用户或文件夹。但是如果某个用户打开了文件夹或文件，操作显然会失败。
我的目标是记录当前持有该文件的用户，包括进程，计算机名称和用户名。
解决方案：
How do I determine the owner of a process in C#?
How do I find out which process is locking a file using .NET?
也尝试用上述解决方案模仿，但它没有用。
在我检查的服务器上computer management-> system tools-> opened files拥有用户的所有日志和其他详细信息。
我的解决方案是完全使用c＃编程的。
由于政策，P.S无法共享任何代码或代码段。

对于任何寻找类似方法或解决方案的人，接受this one here的答案和与管理员权限相结合的模拟，将导致最终输出。
这里有另一个答案：stackoverflow.com/questions/317071/...
我已经为此尝试了多种解决方案，但唯一一个我得到正确答案的是Eric J.已经做出回应。我测试了这个，它适用于正常大小的文件，而且我没有得到任何正确的答案，因为Windows服务锁定的过程（如MSSQL服务）。这是由win32 api完成的。
我只是重申Eric J.的答案：
