文件锁定问题 [英] File lock problem
问题描述
偶尔我尝试保存文件时：
-----------------------
xmlDoc.Save（Application.StartupPath + @" \Config.xml"）;
------------------ -----
我得到这个错误，说该文件无法被访问，因为它的
被另一个进程锁定了（我无法得到它）现在就去做 - 因为
我希望它崩溃...）
有没有办法检查文件是否被另一个进程锁定了
试图保存它？如果它被锁定有没有办法终止其他
进程或某些人将其释放以便可以保存它？
谢谢，
格兰特
我无法解答您的具体问题，但如果我尝试打开文件，我会使用
try / catch并且通常在短时间内循环该过程，其中有一些
thread.sleep（0）被抛入。

不，AFAIK没有办法知道是否一个文件被预先锁定，你有打开它的
并且它会给你错误，使用try / catch块。
这是可能的知道什么进程正在使用给定文件，来自
sysinternals.com的filemon就可以了。怎么样 ？坦率地说，我不知道，IIRC没有一个简单的方法来获取这些信息。当然没有一种管理方式。

Occasionally when I try and save a document:
-----------------------
xmlDoc.Save(Application.StartupPath + @"\Config.xml");
-----------------------
I get this error saying that the file could not be accessed because its
locked by another process or something (I cant get it to do it now - because
I want it to crash...)
Is there a way to check whether a file is locked by another process befre
trying to save it? If it is locked is there a way to terminate the other
process or somewhow free it up so that it can be saved?
Thanks,
Grant
I can''t answer your specific question but if I try to open a file I use
try/catch and usually loop the process over a short time period with some
thread.sleep(0) thrown in.

Hi,
No, AFAIK there is no way to know if a file is locked beforehand, you have
to open it and it will give you error, use a try/catch block .
It''s possible to know what process is using a given file, filemon from
sysinternals.com does it. how ? frankly I have no idea , IIRC there is no a
easy way to get this info. of course there is not a managed way of doing it.
cheers,
