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.

Answer 1

check the code below:

DirectoryInfo dInfo = new DirectoryInfo(strFullPath);

DirectorySecurity dSecurity = dInfo.GetAccessControl();

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

dInfo.SetAccessControl(dSecurity);
