Remarks

Use this constructor when you want to create an empty FileSecurity object that is not based on an existing file. You can then populate the object with access control information and apply it to a file.

You can add access or audit rules to the FileSecurity object using the AddAccessRule method. You can remove access or audit rules using the RemoveAccessRule method.

To persist new or changed access or audit rules to a file, use the SetAccessControl or SetAccessControl method. To retrieve access or audit rules from an existing file, use the GetAccessControl or GetAccessControl method.

Applies to

FileSecurity(String, AccessControlSections)

 FileSecurity(System::String ^ fileName, System::Security::AccessControl::AccessControlSections includeSections);
public FileSecurity (string fileName, System.Security.AccessControl.AccessControlSections includeSections);
new System.Security.AccessControl.FileSecurity : string * System.Security.AccessControl.AccessControlSections -> System.Security.AccessControl.FileSecurity
Public Sub New (fileName As String, includeSections As AccessControlSections)

Parameters

Remarks

This constructor retrieves the access control information for the specified file and then creates a FileSecurity object that encapsulates that information. You can then inspect, add, or delete the access control information for the specified file.

You can add access or audit rules to the FileSecurity object using the AddAccessRule method. You can remove access or audit rules using the RemoveAccessRule method.

To persist new or changed access or audit rules to a file, use the SetAccessControl or SetAccessControl method. To retrieve access or audit rules from an existing file, use the GetAccessControl or GetAccessControl method.

Notes to Callers

The FileSecurity(String, AccessControlSections) constructor requires the current account to have administrative privileges. To create a new instance of the FileSecurity class for a specific file using an account that does not have administrative privileges, use the GetAccessControl() method.
