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

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

$authprov = Get-SPAuthenticationProvider -WebApplication [web application URL] -Zone [zone]
# Check the AllowAnonymous property:
$authprov.AllowAnonymous 

Should return true or false

Answer 2

I should have specified in my post, but I was looking for how to do this in C#. I got the answer I was looking for in this link. Here's the code I basically wound up using by utilizing the IisSettings property of the SPWebApplication object:

Dictionary<SPUrlZone, SPIisSettings> settings = webApplication.IisSettings;

foreach (KeyValuePair<SPUrlZone, SPIisSettings> setting in settings)
{
    bool allowAnon = setting.Value.AllowAnonymous;

    //TODO handle stuff with this info
}
