如何知道哪些进程正在使用ASP.NET下的文件？ [英] How to know which processes is using a file under ASP.NET?

问题描述

我正在开发一个多线程的ASP.NET 3.5应用程序，使用了一些文件工作过程中，我发现了以下异常：

I'm developing a multi-threaded ASP.NET 3.5 application, during working with some file, I'm getting the following exception :

该进程无法访问该文件   因为它是正由另一个   过程

The process cannot access the file because it is being used by another process

我在寻找一种方式来知道到底是哪个进程锁定的文件，所以我可以阻止其访问该文件。或如果是复杂的，我想一个办法来锁定我的线程文件，以便其他线程/进程无法访问它。谢谢你。

I'm looking for a way to know exactly which process is locking that file so I can stop its access to the file. OR if that is complicated, I want a way to lock the file by my thread so other threads/processes can't access it. Thanks.

推荐答案

要真正锁定对资源的访问（你建议的第二个选项），你可以使用一个互斥锁（互斥）。

To actually lock access to the resource (the 2nd option you suggest), you could use a Mutex (a Mutual Exclusion).

我没有做任何这在.NET中，但似乎的好文章的就可以了。

I've not done any of this in .NET, but there seems to be good articles on it.
