CodeGo.net>如何序列化包含字典的类?

作者:互联网

我有以下课程:

[Serializable]
public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public Dictionary<string, string> Attributes { get; set; }
}

我想使用XmlSerializer对其进行序列化,并获得以下输出:

<Person>
    <FirstName>John</FirstName>
    <LastName>Doe</LastName>
    <Attributes>
        <PhoneNumber>12345</PhoneNumber>
        <StreetName>...</StreetName>
        <StreetNumber>...</StreetNumber>
        ...
    </Attributes>
</Person>

任何帮助,将不胜感激.

解决方法:

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

        namespace CSharpSampleApplication.Data.CoreObjects
        {
            [XmlRoot("dictionary")]
            public class SerializableDictionary<TKey, TValue> : Dictionary<TKey, TValue>, IXmlSerializable
            {

                #region IXmlSerializable Members
                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();
                    }
                }

                #endregion

            }
        }
