Applies access control list (ACL) entries described by a DirectorySecurity object to the specified directory.
Assembly: mscorlib (in mscorlib.dll)
static member SetAccessControl : path:string * directorySecurity:DirectorySecurity -> unit
The directorySecurity parameter is a null reference (Nothing in Visual Basic).
The directory could not be found.
The path was invalid.
The current process does not have access to the directory specified by path.
The current process does not have sufficient privilege to set the ACL entry.
The current operating system is not Windows 2000 or later.
The method applies access control list (ACL) entries to a file that represents the noninherited ACL list.
The ACL specified for the directorySecurity parameter replaces the existing ACL for the directory. To add permissions for a new user, use the GetAccessControl method to obtain the existing ACL and modify it.
An 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 Access Control List Entries.
The method persists only DirectorySecurity objects that have been modified after object creation. If a DirectorySecurity object has not been modified, it will not be persisted to a file. Therefore, it is not possible to retrieve a DirectorySecurity object from one file and reapply the same object to another file.
To copy ACL information from one file to another:
Create a new DirectorySecurity object for the destination file.
Set the destination DirectorySecurity object to the destination file using the method.
In NTFS environments, ReadAttributes and ReadExtendedAttributes are granted to the user if the user has ListDirectory rights on the parent folder. To deny ReadAttributes and ReadExtendedAttributes, deny ListDirectory on the parent directory.
The following code example uses the GetAccessControl and the methods to add an access control list (ACL) entry and then remove an ACL entry from a directory. You must supply a valid user or group account to run this example.
