FormsAuthenticationUser Class

Configures the user's credentials for Web applications that use forms-based authentication.

Namespace:  System.Web.Configuration
Assembly:  System.Web (in System.Web.dll)

public sealed class FormsAuthenticationUser : ConfigurationElement

The FormsAuthenticationUser class provides a way to programmatically access and modify the user section of a configuration file.

This type is part of a group that includes the FormsAuthenticationCredentials, the FormsAuthenticationUserCollection, and the FormsAuthenticationConfiguration types. The types other than the collection type directly affect the underlying configuration tags.

NoteNote:

The FormsAuthenticationUser can write information into the related section of the configuration file at machine, site, or application level only. Any attempt to write in a configuration file at a different level in the hierarchy will result in an error message generated by the parser. However, you can use this class to read configuration information at any level in the hierarchy. For safety and scalability, it is recommended that you use an external repository, such as a database, to keep the users' credentials.

The following code example shows how to obtain the FormsAuthenticationUserCollection to access the FormsAuthenticationUser objects of an existing Web application. The configuration file will contain a setup similar to the following.

NoteNote:

If you use the credentials Element for forms for authentication (ASP.NET Settings Schema) section, be sure to follow the guidelines explained at ASP.NET Authentication. For scalability and better security, it is recommended you use an external database to store the users' credentials.
