如何将文件复制到C：\\ Program Files（x86）\\

Question

I can copy files to the C:\\Program Files (x86)\\... ...but only with the administrator account.

This file is a configuration file like App.Config , but with a different name, and I want to put it into the application path's sub folder.

The scenario is like following.

1. Put the initial configuration file in the \\Cfg\\org.cfg

2. When start application program,myApp.exe, check if configuration file exists in the application path.

3. If it doesn't exist, copy org.cfg to the myApp.exe.config and load it.

I tried DirectoryInfo.SetAccessControl() but following error occur as well.

"Attempted to perform an unauthorized operation"

Answer 1

Program Files (x86) required administrative permission to write to. So does changing the permissions, which is why SetAccessControl fails. There's really no way around that. If you want to have your configuration file writable by the application, then you might consider changing the permission of the configuration file during installation of the program when you do have administrative access.

I would instead however recommend putting your configuration file somewhere in the user's profile, which is writable by default for all users, like in %LOCALAPPDATA% .

You can load configuration files from arbitrary locations as well, it doesn't have to be in the .config file next to the executable. For an example of that, look at this question .
