System.ArgumentException: An item with the same key has already been added

[horacioj]

Hi,

Please see https://github.com/rackspace/csharp-cloudfiles/issues/51, the last comment by 'horacioj' The exception does happens in fact in this library (which I wish I could be able to understand and fix myself, but unfortunately I'm not that smart...)

   var query = new Dictionary<ObjectQuery, string>();
   query.Add(ObjectQuery.Prefix, "folder1/");
   query.Add(ObjectQuery.Delimiter, "/");
   list = container.GetObjectList(query);

Exception:
System.ArgumentException: An item with the same key has already been added.

in '_client' ("public override ContainerResponse GetContainer(string url, string token, string container, Dictionary<string, string> headers, Dictionary<string, string> query, bool full_listing)") what happens is:

...
...
while (reader.Read())
            {
                switch (reader.NodeType)
                {
                    case XmlNodeType.Element:
                        if (reader.Name != "xml" && 
                            reader.Name != "container" && 
                            reader.Name != "object")
                        { 
                            var key = reader.Name;
                            reader.Read();
                            info.Add(key, reader.Value);    ////===== EXCEPTION HERE. NOTE: key = "subdir"
                        }
                        break;

Thanks
