FormsAuthenticationUser Class

Definition

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

public ref class FormsAuthenticationUser sealed : System::Configuration::ConfigurationElement
public sealed class FormsAuthenticationUser : System.Configuration.ConfigurationElement
type FormsAuthenticationUser = class
    inherit ConfigurationElement
Public NotInheritable Class FormsAuthenticationUser
Inherits ConfigurationElement
Inheritance
FormsAuthenticationUser

Examples

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.

Note

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. For more information about building secure ASP.NET applications, see Securing Your ASP.NET Application and Building Secure ASP.NET Applications: Authentication, Authorization, and Secure Communication.

This example uses SHA1. Due to collision problems with SHA1, Microsoft recommends SHA256.

<authentication mode="Forms">
  <forms name="MyAppCookieName" loginUrl="/login.aspx">
    defaultUrl="formsdefault.aspx"
    protection="Encryption" timeout="5" path="aspnet"
    slidingExpiration="false"
    cookieless="UseCookies" domain="domainName">
    <credentials passwordFormat="SHA1">
      <user name="aspnetuser1"
        password="5BAA61E4C9B93F3F0682250B6CF8331B7EE68FD8"/>
       <user name="aspnetuser2"
         password="E38AD214943DAAD1D64C102FAEC29DE4AFE9DA3D"/>
    </credentials>
  </forms>
</authentication>

// Get the Web application configuration.
System.Configuration.Configuration configuration = 
    WebConfigurationManager.OpenWebConfiguration(
    "/aspnet");
// Get the section.
AuthenticationSection authenticationSection = 
    (AuthenticationSection)configuration.GetSection(
    "system.web/authentication");
// Get the users collection.
FormsAuthenticationUserCollection formsAuthenticationUsers =
    authenticationSection.Forms.Credentials.Users;
' Get the Web application configuration.
  Dim configuration _
  As System.Configuration.Configuration = _
  WebConfigurationManager.OpenWebConfiguration( _
  "/aspnet")
' Get the section.
  Dim authenticationSection _
  As AuthenticationSection = _
  CType(configuration.GetSection( _
  "system.web/authentication"), AuthenticationSection)
' Get the users collection.
  Dim formsAuthenticationUsers _
  As FormsAuthenticationUserCollection = _
  authenticationSection.Forms.Credentials.Users

Remarks

The FormsAuthenticationUser class provides a way to programmatically access and modify the credentials element for forms for authentication 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.

Note

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.
