推荐答案

我不确定这些操作是否锁定文件.

但是，我确实看到很多帖子都抱怨他们这样做.这些声明几乎总是错误的，并且是另一个文件操作锁定了文件，并且当代码到达Move()方法时，将调用异常.

因此，如果您解释这仅仅是出于好奇还是由于您尝试执行某项操作而导致的失败，那么这可能会有所帮助.

如果是后者，则发布一小段代码演示该问题将有助于我们为您提供帮助.

I do not know for certain if these operations lock a file or not.

I do however see a lot of posts complaining that they do. Almost always these claims are wrong and it is another file operation that is locking the file and an exception gets called when the code reaches the Move() method.

Therefore, it might help if you explain whether this is just curiosity on your part or as a result of something that you are trying to do, that has failed.

If the latter, posting a small snippet of code that demonstrates the problem would help us to assist you.

如果您真的想知道会发生什么，请尝试此操作.

1)下载进程监视器 [
3)确保您正在捕获事件&运行有问题的程序.观察代码点击移动"时会发生什么

If you really want to know what happens, try this.

1) Download Process Monitor[^] from Microsoft

2) Create a filter so it''s only capturing events from the program in question

NB: You can create include\exclude filters over ''Actions'', so you don''t see too much info,

3) Make sure you''re capturing events & run the program in question. Watch what happens when the code hits ''Move''
