[DOTNET] Configuration Section Handlers and collections

[Kerry Whelan]

Hi,

I am using Mike Woodring's "Custom Configuration Section Handler" example
at http://staff.develop.com/woodring/dotnet/#elementnormalcfghandler.

The main part is included below and shows how the Hybrid Dictionary is
recursivley filled with xml data from the config file.

public class GeneralCfgHandler : IConfigurationSectionHandler
{
  ReadOnlyNameObjectDictionary ParseSection( XmlNode section )
  {
    ReadOnlyNameObjectDictionary settingsCollection = new
ReadOnlyNameObjectDictionary();
    foreach( XmlNode childNode in section.ChildNodes )
    {
      if( (childNode.NodeType == XmlNodeType.Element) &&
 (childNode.HasChildNodes) )
      {
      if( childNode.ChildNodes[0].NodeType == XmlNodeType.Text )
      {
        settingsCollection.Add(childNode.Name, childNode.InnerText);
      }
      else if( childNode.ChildNodes[0].NodeType == XmlNodeType.Element )
      {
 settingsCollection.Add(childNode.Name, ParseSection(childNode));
     }
   }
 }
 settingsCollection.MakeReadOnly();
 return(settingsCollection);
}

I would like to retrieve the following xml :-

<UserSettings>
  <role>
    <name>Admins</name>
    <users>
      <user>
        <userID>1</userID>
        <userName>Whelank</userName>
 <screens>
   <pos1>1</pos1>
   <pos2>3</pos2>
 </screens>
       </user>
 <user>
        ...
        </user>
     </users>
   </role>
   <role>
   ...
   </role>
</UserSettings>

However, the IDictionary takes only unique keys and so when I try to add
the second instance of 'user' an error occurs. How can I store several
nodes with the same name?

Any help would be appreciated,

Kerry
