How to programmatically determine if anonymous access is enabled for a SharePoint 2010 Web Application?

Question

In Central Administration\Manage Web Applications, there is the ability to enable anonymous access on a web application through the authentication providers. Is there a way to programmatically determine if this option is enabled? Thanks!

Answer 1

This should work for you:

web.Site.WebApplication.IisSettings[Microsoft.SharePoint.Administration.SPUrlZone.Internet].AllowAnonymous

I started with web, but you can start wherever you need obviously. Also make sure you look at the appropriate zone.

Answer 2

The SPWeb object expose the following boolean :

AllowAnonymousAccess

example :

web.AllowAnonymousAccess;

MSDN : Gets a Boolean value that indicates whether anonymous access is allowed for the website
