示例

此示例演示如何以声明方式为 error 节的 customErrors 元素指定值，该元素也可以作为集合的 CustomErrorCollection 元素进行访问。

以下配置文件示例演示如何以声明方式为 error 元素指定值。

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

下面的代码示例演示如何使用该 CustomErrorCollection 类。

// 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

注解

该 CustomErrorCollection 类型允许访问 error section 元素集合的 customErrors 元素。

它属于包含 /a0> 和 的组。
