CustomErrorsSection Class

Configures the ASP.NET custom errors. This class cannot be inherited.

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

public sealed class CustomErrorsSection : ConfigurationSection

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.

NoteNote:

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.

This example demonstrates how to specify values declaratively for several attributes of the customErrors Element (ASP.NET Settings Schema) 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;

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
