Applies access control list (ACL) entries described by a System.Security.AccessControl.DirectorySecurity object to the directory described by the current System.IO.DirectoryInfo object.
Syntax
Parameters
- directorySecurity
Remarks
An access control list (ACL) describes individuals and/or groups who have, or do not have, rights to specific actions on the given file or directory. For more information, see ACL Technology Overview and How to: Add or Remove an Access Control List Entry.
The DirectoryInfo.SetAccessControl(System.Security.AccessControl.DirectorySecurity) method applies ACL entries to a file that represents the noninherited ACL list.
The ACL specified for directorySecurity replaces the existing ACL for the directory. To add permissions for a new user, use the erload:System.IO.DirectoryInfo.GetAccessControl method to obtain the existing ACL, and modify it.
The DirectoryInfo.SetAccessControl(System.Security.AccessControl.DirectorySecurity) method persists only System.Security.AccessControl.DirectorySecurity objects that have been modified after object creation. If a System.Security.AccessControl.DirectorySecurity object has not been modified, it will not be persisted to a file. Therefore, it is not possible to retrieve a System.Security.AccessControl.DirectorySecurity object from one file and reapply the same object to another file.
To copy ACL information from one file to another:
