type CustomErrorsSection = class
    inherit ConfigurationSection
Public NotInheritable Class CustomErrorsSection
Inherits ConfigurationSection

Examples

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

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

<customErrors mode="RemoteOnly"  
  defaultRedirect="customerror.htm">  
    <error statusCode="404" redirect="customerror404.htm"/>  
</customErrors>  

The following example shows how to use the CustomErrorsSection class.


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

// Get the section.
CustomErrorsSection customErrorsSection =
  (CustomErrorsSection)configuration.GetSection(
  "system.web/customErrors");

// Get the collection
CustomErrorCollection customErrorsCollection = 
    customErrorsSection.Errors;

      ' Get the Web application configuration.
        Dim configuration _
        As System.Configuration.Configuration = _
WebConfigurationManager.OpenWebConfiguration( _
        "/aspnetTest")
      
      ' Get the section.
        Dim customErrorsSection _
        As CustomErrorsSection = _
        CType(configuration.GetSection( _
  "system.web/customErrors"), _
  CustomErrorsSection)
      
      ' Get the collection
        Dim customErrorsCollection _
        As CustomErrorCollection = customErrorsSection.Errors
      

Remarks

The CustomErrorsSection class provides a way to programmatically access and modify the customErrors section of a configuration file. This type is part of a group that includes the CustomErrorCollection, CustomErrorsMode, and CustomError types.

Note

The CustomErrorsSection can read and write information from and to the related section of the configuration file according to the section property AllowDefinition whose value is Everywhere.
