C# 4.0 Web.config嵌套列表

我想在我的web.config中使用嵌套列表。我看到了一些可以工作的代码，但不是我的，当我试图阅读配置部分时出现了一个错误：

System.Configuration.ConfigurationErrorsException:未安装 重新连接等时服务系统'

我的配置：

<IsochroneServicesTest>
    <add name="TC">
      <IsochroneServicesTestImbrique>
        <add name="DEFAULT" path="success"/>
      </IsochroneServicesTestImbrique>
    </add>
  </IsochroneServicesTest>

感谢您的帮助

您收到了该错误，因为您在

部分中缺少了

isochroneseservicestistimbrique

的声明。此外，至少必须有一个类继承自

ConfigurationSection

。参见示例

    [ConfigurationProperty("IsochroneServicesTest")]
    [ConfigurationCollection(typeof(CollectionIsochrone), AddItemName = "add")]
    public CollectionIsochroneType IsochroneServicesTest
