使用 NameValueSectionHandler 类型的自定义节组对配置对象调用 Save

Question

我有一个 Configuration 对象，我可以轻松地从中读取和写入设置并调用 Save(ConfigurationSaveMode.Minimal, true) 通常工作得很好。

但是，我现在有一个配置文件，其中定义了 System.Configuration.NameValueSectionHandler （我没有写那部分，我无法更改它）。现在，当我调用 保存< /a> 方法，它会抛出 TypeLoadException消息

：

类型 System.Configuration.NameValueSectionHandler 不继承自 System.Configuration.ConfigurationSectionGroup。

调用堆栈：

at System.Configuration.TypeUtil.VerifyAssignableType
      (Type baseType, Type type, Boolean throwOnError)
at System.Configuration.TypeUtil.GetConstructorWithReflectionPermission
      (Type type, Type baseType, Boolean throwOnError)
at System.Configuration.MgmtConfigurationRecord.CreateSectionGroupFactory
      (FactoryRecord factoryRecord)
at System.Configuration.MgmtConfigurationRecord.EnsureSectionGroupFactory
      (FactoryRecord factoryRecord)
at System.Configuration.MgmtConfigurationRecord.GetSectionGroup
      (String configKey)
at System.Configuration.ConfigurationSectionGroupCollection.Get
      (String name)
at System.Configuration.ConfigurationSectionGroupCollection.
      <GetEnumerator>d__0.MoveNext()
at System.Configuration.Configuration.ForceGroupsRecursive
      (ConfigurationSectionGroup group)
at System.Configuration.Configuration.SaveAsImpl
      (String filename, ConfigurationSaveMode saveMode, Boolean forceSaveAll)
at System.Configuration.Configuration.Save
      (ConfigurationSaveMode saveMode, Boolean forceSaveAll)
at MyCompany.MyProduct.blah.blah.Save
      () in C:\\projects\\blah\\blah\\blah.cs:line blah

仅供参考，配置如下所示

<configuration>
  <configSections>
    ... normal sections here that work just fine, followed by ...

    <sectionGroup name="threadSettings" type="System.Configuration.NameValueSectionHandler">
      <section name="T1" type="System.Configuration.DictionarySectionHandler"/>
      <section name="T2" type="System.Configuration.DictionarySectionHandler"/>
      <section name="T3" type="System.Configuration.DictionarySectionHandler"/>
    </sectionGroup>
  </configSections>
  <applicationSettings />
  <threadSettings>
    <T1>
      <add key="key-here" value="value-here"/>
    </T1>
    ... T2 and T3 here as well, thats not interesting ...
  </threadSettings>
</configuration>

如果我删除实际部分和自定义部分组的定义，我就可以很好地读取/写入设置，甚至可以很好地调用Save。

显然，自定义节组可以设置得更好一些，但我无法解决这个问题，所以我想知道：如果它具有自定义节组，是否可以保存Configuration对象NameValueSectionHandler 类型
