删除关闭文件 [英] Delete on close files

问题描述

使用语言：C＃

理论：
我想创建一个临时文件夹的标志FileOptions.DeleteOnClose的文件。
中的文件创建成功，我写上拿督它，下一步是启动与文件的Process.Start（...）相关的应用程序，并允许用户检查文档，最后我关闭句柄并尽快其他程序关闭句柄到临时文件，该文件是由操作系统删除。

Theory: I want to create a file with the flag FileOptions.DeleteOnClose in a temporary folder. The file is successfully created and I write dato onto it, the next step is to launch the application associated with the file Process.Start(...) and allow the user to inspect the document, finally I close my handle and as soon as other process close the handle to the temporary file, the file is deleted by operating system.

我的问题是其他进程无法打开文件，甚至读书，尽管如果我添加FileShare.ReadWrite | FileShare.Delete到共享模式。

My problem is that other processes cannot open the file, even for reading, despite if I add FileShare.ReadWrite | FileShare.Delete to the sharing mode.

有什么建议？

推荐答案

其他工艺需要指定 FileShare.Delete 当他们打开 DeleteOnClose 文件

The other processes need to specify FileShare.Delete when they open the DeleteOnClose file

从 MSDN的CreateFile 文档：

FILE_FLAG_DELETE_ON_CLOSE ...该文件的后续打开请求失败，除非 FILE_SHARE_DELETE 指定共享模式。

"FILE_FLAG_DELETE_ON_CLOSE... Subsequent open requests for the file fail, unless the FILE_SHARE_DELETE share mode is specified."
