System.Web.Configuration Namespace

.NET Framework version 2.0

Provides programmatic access to the urlMappings configuration file section. This class cannot be inherited.

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

NOTE: The urlMappings section contains UrlMapping objects that map URLs that are displayed to users to URLs that exist in your Web application. The UrlMappingsSection can write information into the related section of the configuration file according to the restrictions defined by the section property AllowDefinition whose value is 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.

The following code example shows how to obtain the UrlMappingsSection object from the configuration file of an existing Web application. Also shown is an excerpt of the configuration file.

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

// Get the <urlMapping> section.
UrlMappingsSection urlMappingSection = ( UrlMappingsSection ) configuration.GetSection 
   ( "system.web/urlMappings" );

// Get the url mapping collection.
UrlMappingCollection urlMappings = urlMappingSection.UrlMappings;

' Get the Web application configuration.
Dim configuration As Configuration = WebConfigurationManager.OpenWebConfiguration ( "/aspnetTest" )

' Get the <urlMapping> section.
Dim urlMappingSection As UrlMappingsSection = CType ( configuration.GetSection 
   ( "system.web/urlMappings" ), UrlMappingsSection )

' Get the url mapping collection.
Dim urlMappings As UrlMappingCollection = urlMappingSection.UrlMappings

<urlMappings enabled = "true">
   <add url= "~/home.aspx"
      mappedUrl = "~/default.aspx?parm1=1" />
   <add url= "~/products.aspx"
      mappedUrl = "~/default.aspx?parm1=2" />
</urlMappings>
