Detecting Web.Config Authentication Mode

Say I have the following web.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.web>
        <authentication mode="Windows"></authentication>
    </system.web>
</configuration>

Using ASP.NET C#, how can I detect the Mode value of the Authentication tag?

In ASP.Net Core you can use this:

public Startup(IHostingEnvironment env, IConfiguration config)
{
    var enabledAuthTypes = config["IIS_HTTPAUTH"].Split(';').Where(l => !String.IsNullOrWhiteSpace(l)).ToList();
}

You can also get the authentication mode by using the static ConfigurationManager class to get the section and then the enum AuthenticationMode.

AuthenticationMode authMode = ((AuthenticationSection) ConfigurationManager.GetSection("system.web/authentication")).Mode;

The difference between WebConfigurationManager and ConfigurationManager

If you want to retrieve the name of the constant in the specified enumeration you can do this by using the Enum.GetName(Type, Object) method

Enum.GetName(typeof(AuthenticationMode), authMode); // e.g. "Windows"

Import the System.Web.Configuration namespace and do something like:

var configuration = WebConfigurationManager.OpenWebConfiguration("/");
var authenticationSection = (AuthenticationSection)configuration.GetSection("system.web/authentication");
if (authenticationSection.Mode == AuthenticationMode.Forms)
{
  //do something
}

use an xpath query //configuration/system.web/authentication[mode] ?

protected void Page_Load(object sender, EventArgs e)
{
 XmlDocument config = new XmlDocument();
 config.Load(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
 XmlNode node = config.SelectSingleNode("//configuration/system.web/authentication");
 this.Label1.Text = node.Attributes["mode"].Value;
}

The mode property from the authenticationsection: AuthenticationSection.Mode Property (System.Web.Configuration). And you can even modify it.

// Get the current Mode property.
AuthenticationMode currentMode = 
    authenticationSection.Mode;

// Set the Mode property to Windows.
authenticationSection.Mode = 
    AuthenticationMode.Windows;

This article describes how to get a reference to the AuthenticationSection.
