public sealed class FormsAuthenticationCredentials : ConfigurationElement

NameDescription
System_CAPS_pubmethodFormsAuthenticationCredentials()

This API supports the product infrastructure and is not intended to be used directly from your code. Initializes a new instance of the FormsAuthenticationCredentials class.

NameDescription
System_CAPS_pubpropertyCurrentConfiguration

Gets a reference to the top-level Configuration instance that represents the configuration hierarchy that the current ConfigurationElement instance belongs to.(Inherited from ConfigurationElement.)

System_CAPS_pubpropertyElementInformation

Gets an ElementInformation object that contains the non-customizable information and functionality of the ConfigurationElement object. (Inherited from ConfigurationElement.)

System_CAPS_protpropertyElementProperty

Gets the ConfigurationElementProperty object that represents the ConfigurationElement object itself.(Inherited from ConfigurationElement.)

System_CAPS_protpropertyItem[ConfigurationProperty]

Gets or sets a property or attribute of this configuration element.(Inherited from ConfigurationElement.)

System_CAPS_protpropertyItem[String]

Gets or sets a property, attribute, or child element of this configuration element.(Inherited from ConfigurationElement.)

System_CAPS_pubpropertyLockAllAttributesExcept

Gets the collection of locked attributes.(Inherited from ConfigurationElement.)

System_CAPS_pubpropertyLockAllElementsExcept

Gets the collection of locked elements.(Inherited from ConfigurationElement.)

System_CAPS_pubpropertyLockAttributes

Gets the collection of locked attributes (Inherited from ConfigurationElement.)

System_CAPS_pubpropertyLockElements

Gets the collection of locked elements.(Inherited from ConfigurationElement.)

System_CAPS_pubpropertyLockItem

Gets or sets a value indicating whether the element is locked.(Inherited from ConfigurationElement.)

System_CAPS_pubpropertyPasswordFormat

Gets or sets the password format.

System_CAPS_protpropertyProperties

Gets the collection of properties.(Inherited from ConfigurationElement.)

System_CAPS_pubpropertyUsers

Gets the users' names and password credentials.

NameDescription
System_CAPS_protmethodDeserializeElement(XmlReader, Boolean)

Reads XML from the configuration file.(Inherited from ConfigurationElement.)

System_CAPS_pubmethodEquals(Object)

Compares the current ConfigurationElement instance to the specified object.(Inherited from ConfigurationElement.)

System_CAPS_pubmethodGetHashCode()

Gets a unique value representing the current ConfigurationElement instance.(Inherited from ConfigurationElement.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodInit()

Sets the ConfigurationElement object to its initial state.(Inherited from ConfigurationElement.)

System_CAPS_protmethodInitializeDefault()

Used to initialize a default set of values for the ConfigurationElement object.(Inherited from ConfigurationElement.)

System_CAPS_protmethodIsModified()

Indicates whether this configuration element has been modified since it was last saved or loaded, when implemented in a derived class.(Inherited from ConfigurationElement.)

System_CAPS_pubmethodIsReadOnly()

Gets a value indicating whether the ConfigurationElement object is read-only.(Inherited from ConfigurationElement.)

System_CAPS_protmethodReset(ConfigurationElement)

Resets the internal state of the ConfigurationElement object, including the locks and the properties collections.(Inherited from ConfigurationElement.)

System_CAPS_protmethodResetModified()

Resets the value of the IsModified method to false when implemented in a derived class.(Inherited from ConfigurationElement.)

System_CAPS_protmethodSerializeElement(XmlWriter, Boolean)

Writes the contents of this configuration element to the configuration file when implemented in a derived class.(Inherited from ConfigurationElement.)

System_CAPS_protmethodSerializeToXmlElement(XmlWriter, String)

Writes the outer tags of this configuration element to the configuration file when implemented in a derived class.(Inherited from ConfigurationElement.)

System_CAPS_protmethodSetReadOnly()

Sets the IsReadOnly property for the ConfigurationElement object and all subelements.(Inherited from ConfigurationElement.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_protmethodUnmerge(ConfigurationElement, ConfigurationElement, ConfigurationSaveMode)

Modifies the ConfigurationElement object to remove all values that should not be saved. (Inherited from ConfigurationElement.)

The FormsAuthenticationCredentials class provides a way to programmatically access and modify the credentials element of a forms section in the authentication section of the configuration file. This type is part of a group that includes the FormsAuthenticationConfiguration, the FormsAuthenticationUserCollection, and the FormsAuthenticationUser types. With the exception of the collection type, all the others directly affect the underlying configuration tags.

System_CAPS_noteNote

The FormsAuthenticationCredentials can write information into the related section of the configuration file according to the restrictions defined by MachineToApplication. Any attempt to write in a configuration file at a level not allowed 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.

This example demonstrates how to specify values declaratively for several attributes of the credentials section, which can also be accessed as members of the FormsAuthenticationCredentials class.

The following configuration file example shows how to specify values declaratively for the credentials section.

<credentials passwordFormat="SHA1">
  <user name="aspnetuser1"
    password="5BAA61E4C9B93F3F0682250B6CF8331B7EE68FD8"/>
  <user name="aspnetuser2"
    password="E38AD214943DAAD1D64C102FAEC29DE4AFE9DA3D"/>
</credentials>
System_CAPS_noteNote

If you use the credentials section, be sure to follow the guidelines explained at ASP.NET Authentication. For scalability and better security, it is recommended that you use an external database to store the users' credentials. For more information about building secure ASP.NET applications, search the Microsoft MSDN Web site (http://msdn.microsoft.com) for "Securing Your ASP.NET Application" and "Building Secure ASP.NET Applications: Authentication, Authorization, and Secure Communication."

The following code example demonstrates how to use the FormsAuthenticationCredentials class.


// Get the Web application configuration.
System.Configuration.Configuration configuration = 
    WebConfigurationManager.OpenWebConfiguration("/aspnetTest");

// Get the authentication section.
AuthenticationSection authenticationSection = 
    (AuthenticationSection)configuration.GetSection(
    "system.web/authentication");

// Get the forms credentials collection .
FormsAuthenticationCredentials formsAuthenticationCredentials =
    authenticationSection.Forms.Credentials;
