The PipeSecurity.RemoveAuditRuleSpecific(PipeAuditRule) method removes the specified matching System.Security.AccessControl.AccessControlType.Deny audit rule or the specified matching System.Security.AccessControl.AccessControlType.Allow audit rule from the current System.IO.Pipes.PipeSecurity object. For example, you can use this method to remove a specified System.Security.AccessControl.AccessControlType.Deny audit rule for a user by passing a System.Security.AccessControl.FileSystemAuditRule object created using the System.Security.AccessControl.AccessControlType.Deny value, the System.Security.AccessControl.AuditFlags.Failure value, and a user account. When you do this, the PipeSecurity.RemoveAuditRuleSpecific(PipeAuditRule) method removes only a deny rule that specifies the System.Security.AccessControl.AuditFlags.Failure value. It does not remove any deny rules that specify the System.Security.AccessControl.AuditFlags.Success value.
