FileSystemSecurity.RemoveAuditRule Method (FileSystemAuditRule)

Note: This method is new in the .NET Framework version 2.0.

Removes all matching allow or deny audit rules from the current file or directory.

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

public bool RemoveAuditRule (
	FileSystemAuditRule rule
)
public boolean RemoveAuditRule (
	FileSystemAuditRule rule
)
public function RemoveAuditRule (
	rule : FileSystemAuditRule
) : boolean

Parameters

rule

A FileSystemAuditRule object that represents an audit rule to remove from a file or directory.

Return Value

true if the audit rule was removed; otherwise, false

Exception typeCondition

ArgumentNullException

The rule parameter is a null reference (Nothing in Visual Basic).

The RemoveAuditRule method removes either all matching Deny audit rules or all matching Allow audit rules from the current FileSystemSecurity object. For example, you can use this method to remove all Deny audit rules for a user by passing a FileSystemAuditRule object created using the Deny value, the Failure value, and a user account. When you do this, the RemoveAuditRule method removes any deny rules that specify the Failure value or the Success value.

The following code example uses the AddAuditRule method to add an audit rule to a file and uses the RemoveAuditRule method to remove the audit rule from the file. You must supply a valid user or group account to run this example.

using System.IO;
using System.Security.AccessControl;

namespace FileSystemExample
{
    class FileExample
    {
        public static void Main()
        {
            try
            {
                string FileName = "test.xml";

                Console.WriteLine("Adding access control entry for " + FileName);

                // Add the access control entry to the file.
                AddFileAuditRule(FileName, @"MYDOMAIN\MyAccount", FileSystemRights.ReadData, AuditFlags.Failure);

                Console.WriteLine("Removing access control entry from " + FileName);

                // Remove the access control entry from the file.
                RemoveFileAuditRule(FileName, @"MYDOMAIN\MyAccount", FileSystemRights.ReadData, AuditFlags.Failure);

                Console.WriteLine("Done.");
            }
            catch (Exception e)
            {
                Console.WriteLine(e);
            }

            Console.ReadLine();
        }

        {


            // Get a FileSecurity object that represents the 
            // current security settings.
            FileSecurity fSecurity = File.GetAccessControl(FileName);

            // Add the FileSystemAuditRule to the security settings. 
            fSecurity.AddAuditRule(new FileSystemAuditRule(Account,
                                                            Rights,
                                                            AuditRule));

            // Set the new access settings.
            File.SetAccessControl(FileName, fSecurity);

        }

        // Removes an ACL entry on the specified file for the specified account.
        public static void RemoveFileAuditRule(string FileName, string Account, FileSystemRights Rights, AuditFlags AuditRule)
        {

            // Get a FileSecurity object that represents the 
            // current security settings.
            FileSecurity fSecurity = File.GetAccessControl(FileName);

            // Add the FileSystemAuditRule to the security settings. 
            fSecurity.RemoveAuditRule(new FileSystemAuditRule(Account,
                                                            Rights,
                                                            AuditRule));

            // Set the new access settings.
            File.SetAccessControl(FileName, fSecurity);

        }
    }
}
