The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Namespace:   System.Security.Permissions
Assembly:  mscorlib (in mscorlib.dll)

	FileIOPermissionAccess access,
	AccessControlActions control,
	String^ path


Type: System.Security.Permissions::FileIOPermissionAccess

A bitwise combination of the FileIOPermissionAccess enumeration values.

Type: System.Security.AccessControl::AccessControlActions

A bitwise combination of the AccessControlActions enumeration values.

Type: System::String^

The absolute path of the file or directory.

Exception Condition

The access parameter is not a valid value of FileIOPermissionAccess.


The path parameter is not a valid string.


The path parameter does not specify the absolute path to the file or directory.

This constructor allows only one FileIOPermissionAccess value to be specified for the specified file or directories. Use the AddPathList method to define complex permissions.

The control parameter specifies whether the access control list (ACL) for the file or directory specified by path can be changed, viewed, or cannot be accessed.


An access control list (ACL) describes individuals or groups who have, or do not have, rights to specific actions on the given file and its properties. The ability to change or view an ACL is an important permission and should be granted with caution.
