File.WriteAllText throws UnauthorizedAccessException
提问by ripper234
Doing File.WriteAllTextto a remote path throws UnauthorizedAccessException. When I open the file in notepad I can edit it without a problem. The process that's trying to modify the file is running as my own user account, so it should be able to access it.
否则File.WriteAllText到远程路径抛出UnauthorizedAccessException。当我在记事本中打开文件时，我可以毫无问题地编辑它。尝试修改文件的进程正在以我自己的用户帐户运行，因此它应该能够访问它。

According to MSDN, UnauthorizedAccessExceptioncan also be caused by:
根据MSDN，UnauthorizedAccessException也可能由以下原因引起：
path specified a file that is read-only. -or- This operation is not supported on the current platform. -or- path specified a directory.
path specified a file that is read-only. -or- This operation is not supported on the current platform. -or- path specified a directory.
Is it possible one of these conditions is the cause of your problem?
这些情况之一是否可能是您的问题的原因？

The UnauthorizedAccessExceptionis also thrown if the file has the "hidden" attribute set. Don't ask me why...
该UnauthorizedAccessException如果该文件具有“隐藏”属性设置也抛出。不要问我为什么...

I believe you also get this exception (although its not documented) if the file is being locked by another process or thread.
我相信如果文件被另一个进程或线程锁定，你也会得到这个异常（虽然它没有记录）。
Make sure nothing else has opened the file in a manner that prohibits writing. Notepad is not a good test for seeing if a file is locked, since it will open a locked file (ie: read-only files are fine).
确保没有其他任何东西以禁止写入的方式打开文件。记事本不是查看文件是否被锁定的好测试，因为它会打开一个锁定的文件（即：只读文件很好）。
