WebPartsSection 類別

定義

提供程式設計存取給 webParts 組態檔區段。 此類別無法獲得繼承。

public ref class WebPartsSection sealed : System::Configuration::ConfigurationSection
public sealed class WebPartsSection : System.Configuration.ConfigurationSection
type WebPartsSection = class
    inherit ConfigurationSection
Public NotInheritable Class WebPartsSection
Inherits ConfigurationSection

範例

這個範例示範如何針對 區段的 webParts 數個屬性以宣告方式指定值,而這個屬性也可以當做 類別的成員 WebPartsSection 存取。

下列組態檔範例示範如何以宣告方式指定 webParts 區段的值。

<system.web>  
  <webParts>  
    <personalization  
      defaultProvider=" AspNetSqlPersonalizationProvider ">  
        <!-- Providers may only be defined at the   
            application level -->  
      <providers>  
        <add name="AspNetSqlPersonalizationProvider"  
type="System.Web.UI.WebControls.WebParts.SqlPersonalizationProvider"  
        connectionStringName="LocalSqlServer"  
        applicationName="/" />        
      </providers>  
      <authorization>  
        <deny users="*" verbs="enterSharedScope" />  
        <allow users="Admin" verbs="modifyState" />
