避免在复制档案和向它提交另一处理文件时出现错误
原标题:Avoid errors while copying a file and another process writes to it

i 撰写一个简单的文件同步。

Therefore i want at the time a file is created in the source folder it should be copied to the destination.

我的问题是:在试图阅读来文方档案时,如何避免错误,因为另一个过程可能想写给它? 一读到“读写共享模式”中的文档或简单系统。 IO.File.Copy sufficient ?

感谢!

File Copy will lock the file while it is being copied.
If it wasn t locked, the file could be corrupted during the copy by another process
So, when you start the copy process there are two possibilities:

  • None has a lock on your source file, then File.Copy start its work and locks the source file.
  • Someone has a lock on your source file, then File.Copy will throw an exception.
