如何使用ConfigurationManager.GetSection(columnsSectionName)获取.config文件的内容而不更改部分的顺序?

在我的配置部分,我有以下内容:

<configuration>
  <configSections>
    <section name="nlog" type="NLog.Config.ConfigSectionHandler, NLog"/>
    <section name="NFeColumns" type="System.Configuration.DictionarySectionHandler" />
    <section name="CTeColumns" type="System.Configuration.DictionarySectionHandler" />
  </configSections>

  <appSettings>
    <add key="csv.separator" value=";" />
    <add key="infNFe.columns" value="NFeColumns"/>
    <add key="infCte.columns" value="CTeColumns"/>
    <add key="infNFe.filename" value=".\Extracted\NFeCollection.csv"/>
    <add key="infCte.filename" value=".\Extracted\CTeCollection.csv"/>
  </appSettings>

  <NFeColumns>
    <add key="infNFe.Id"  value="Id" />
    <add key="ide.cUF"    value="cUF" />
    <add key="dest.CNPJ"  value="CNPJ" />
    <add key="dest.xNome" value="xNome" />
    <add key="det.nItem"  value="nItem" />
    <add key="prod.cProd" value="cProd" />
    <add key="prod.xProd" value="xProd" />
    <add key="IPI.cEnq"   value="cEnq" />
  </NFeColumns>

  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
  </startup>

</configuration>

我希望以与配置文件相同的顺序捕获值并放入IDictionary。我这样做:

 string columnsSectionName = ConfigurationManager.AppSettings[colFileName + ".columns"];
            IDictionary columns = (IDictionary)ConfigurationManager.GetSection(columnsSectionName);

然而,我m geting the <NFeColumns> in a totally different order, and I can弄清楚原因。你能帮我吗?

ConfigurationManager.GetSection返回HashTable的实例。哈希表中的项目不会按插入顺序存储。您必须手动订购它们。
