I use this util class for serializing dictionaries, maybe it can be useful for you

using System.Collections.Generic;
using System.Xml;
using System.Xml.Schema;
using System.Xml.Serialization;

namespace Utils {
    ///

    ///
    public class SerializableDictionary : IXmlSerializable {
        private readonly IDictionary dic;
        public DiccionarioSerializable() {
            dic = new Dictionary();
        }
        public SerializableDictionary(IDictionary dic) {
            this.dic = dic;
        }
        public IDictionary Dictionary {
            get { return dic; }
        }
        public XmlSchema GetSchema() {
            return null;
        }
        public void WriteXml(XmlWriter w) {
            w.WriteStartElement("dictionary");
            foreach (int key in dic.Keys) {
                string val = dic[key];
                w.WriteStartElement("item");
                w.WriteElementString("key", key.ToString());
                w.WriteElementString("value", val);
                w.WriteEndElement();
            }
            w.WriteEndElement();
        }
        public void ReadXml(XmlReader r) {
            if (r.Name != "dictionary") r.Read(); // move past container
            r.ReadStartElement("dictionary");
            while (r.NodeType != XmlNodeType.EndElement) {
                r.ReadStartElement("item");
                string key = r.ReadElementString("key");
                string value = r.ReadElementString("value");
                r.ReadEndElement();
                r.MoveToContent();
                dic.Add(Convert.ToInt32(key), value);
            }
        }
    }
