how to set folder ACLs from C#

Question

How can I automate the following manual steps in C#?

• Right click a folder in Windows Explorer;

  Properties -> Security -> Advanced -> Edit

• Un-tick "Include inheritable permissions from this object's parent" and click Remove.

• Click Add, choose a group and grant it Modify rights.

I've found this article, which looks like exactly what i need, but I don't have and cant find Microsoft.Win32.Security

Thanks

Answer 1

I don't know about that one, but you should be able to do that via the DirectorySecurity class in the System.Security.AccessControl namespace.

And I assume you'd probably want to look at the InheritanceFlags enumeration as well.

Answer 2

check the code below:

DirectoryInfo dInfo = new DirectoryInfo(strFullPath);

DirectorySecurity dSecurity = dInfo.GetAccessControl();

dSecurity.SetAccessRuleProtection(true, true); //check off & copy inherited security setting

dInfo.SetAccessControl(dSecurity);
