如何确定，因为一个共享冲突，如果抛出IOException？ [英] How do I determine if an IOException is thrown because of a sharing violation?

问题描述

我有一个C＃应用程序，我想将文件复制到一个新的位置。有些时候我需要覆盖现有文件。 发生这种情况时我收到System.IO.IOException。我想从一个共享冲突恢复，但我怎么确定IOException异常返回，因为该目标文件正在使用中而不是其他原因？我可以寻找的过程，因为它是被另一个进程无法访问该文件。消息......但我不喜欢这个主意。

I have a C# application and I want to copy a file to a new location. Some times I need to overwrite an existing file. when this happens I receive a System.IO.IOException. I want to recover from a Sharing violation but how do I determine that IOException was returned because the destination file is in use rather then some other reason? I could look for the "The process cannot access the file because it is being used by another process." message... But I don't like that idea.
