WebPartsSection 类
定义
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
提供对 webParts 配置文件节的编程访问。 此类不能被继承。

示例
此示例演示如何以声明方式为节的 webParts 多个属性指定值，这些属性也可以作为 类的成员 WebPartsSection 进行访问。
以下配置文件示例演示如何以声明方式为 webParts 节指定值。
<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" />
</authorization>
</personalization>
<transformers>
<add name="RowToFieldTransformer"
type="System.Web.UI.WebControls.WebParts.RowToFieldTransformer" />
<add name="RowToFilterTransformer"
type="System.Web.UI.WebControls.WebParts.RowToFilterTransformer" />
<add name="RowToParametersTransformer"
type="System.Web.UI.WebControls.WebParts.RowToParametersTransformer" />
</transformers>
</webParts>
</system.web>

注解
使用 webParts 配置文件部分，可以指定 Web 部件个性化设置提供程序、设置个性化设置授权，并添加扩展 WebPartTransformer 类以供 Web 部件连接使用的自定义类。
构造函数
| WebPartsSection() |
使用默认设置初始化 WebPartsSection 类的新实例。 |
