.NET XML序列化陷阱？

Question

我在做C＃XML序列化时遇到了一些陷阱，我想分享一下：您无法序列化只读项（例如KeyValuePairs）您无法序列化通用词典。相反，请尝试以下包装器类（来自http://weblogs.asp.net/pwelter34/archive/2006/05/03/444961.aspx）：using System;using System.Collections.Generic;using System.Text;using System.Xml.Serialization;[XmlRoot("dictionary")]public class SerializableDictionary<TKey, TValue> : Dictionary<TKey, TValue>, IXmlSerializable{          public System.Xml.Schema.XmlSchema GetSchema()    {        return null;    }    public void ReadXml(System.Xml.XmlReader reader)    {        XmlSerializer keySerializer = new XmlSerializer(typeof(TKey));        XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue));        bool wasEmpty = reader.IsEmptyElement;        reader.Read();        if (wasEmpty)            return;        while (reader.NodeType != System.Xml.XmlNodeType.EndElement)        {            reader.ReadStartElement("item");            reader.ReadStartElement("key");            TKey key = (TKey)keySerializer.Deserialize(reader);            reader.ReadEndElement();            reader.ReadStartElement("value");            TValue value = (TValue)valueSerializer.Deserialize(reader);            reader.ReadEndElement();            this.Add(key, value);            reader.ReadEndElement();            reader.MoveToContent();        }        reader.ReadEndElement();    }    public void WriteXml(System.Xml.XmlWriter writer)    {        XmlSerializer keySerializer = new XmlSerializer(typeof(TKey));        XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue));        foreach (TKey key in this.Keys)        {            writer.WriteStartElement("item");            writer.WriteStartElement("key");            keySerializer.Serialize(writer, key);            writer.WriteEndElement();            writer.WriteStartElement("value");            TValue value = this[key];            valueSerializer.Serialize(writer, value);            writer.WriteEndElement();            writer.WriteEndElement();        }    }}还有其他XML序列化陷阱吗？
