public sealed class CustomErrorsSection : System.Configuration.ConfigurationSection
type CustomErrorsSection = class
    inherit ConfigurationSection
Public NotInheritable Class CustomErrorsSection
Inherits ConfigurationSection
继承

示例

此示例演示如何以声明方式为 customErrors 部分的多个属性指定值,也可以将这些属性作为类的成员进行访问 CustomErrorsSectionThis example demonstrates how to specify values declaratively for several attributes of the customErrors section, which can also be accessed as members of the CustomErrorsSection class.

下面的配置文件示例演示如何以声明方式为节指定值 customErrorsThe 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>  

下面的示例演示如何使用 CustomErrorsSection 类。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
