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)，这通常可以正常工作。

但是，我现在有一个配置文件，其自定义sectionGroup定义为类型System.Configuration.NameValueSectionHandler（我没有写那部分，我无法更改它）。现在，当我调用Save方法时，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

供参考，配置如下

<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>

如果删除实际部分和自定义部分组的定义，我可以很好地读取/写入设置，甚至可以正常调用Save。

显然，自定义部分组可以设置得更好但我无法修复，所以我想知道：是否有可能让Configuration对象保存，如果它有自定义sectionGroups NameValueSectionHandler类型

使用NameValueSectionHandler类型的自定义节组调用配置obj上的Save
