.NET中XML序列化和反序列化常用类和用来控制XML序列化的属性总结

序列化和反序列化是指什么？

序列化(seriallization)：将对象转化为便于传输的数据格式， 常见的序列化格式：二进制格式，字节数组，json字符串，xml字符串。
反序列化(deseriallization)：将序列化的数据恢复为对象的过程。.

XmlSerializer类

该类用一种高度松散耦合的方式提供串行化服务。你的类不需要继承特别的基类，而且它们也不需要实现特别的接口。相反，你只需在你的类或者这些类的公共域以及读/写属性里加上自定义的特性。XmlSerializer通过反射机制读取这些特性并用它们将你的类和类成员映射到xml元素和节点上（在对象和 XML文档之间进行序列化和反序列化操作）。

.NET-XML序列化和反序列化简单示例代码

using System.IO;
using System.Xml.Serialization; 
namespace Practices.Common
{
    public class SimpleSerializer
    {
        /// <summary>
        /// Model实体对象序列化为XML字符串
        /// </summary>
        /// <typeparam name="T">对象类型</typeparam>
        /// <param name="t">Model实体对象</param>
        /// <returns></returns>
        public static string SerializeXMLL<T>(T t)
        {
            using (StringWriter sw = new StringWriter())
            {
                XmlSerializer xmlSerializer = new XmlSerializer(t.GetType());
                xmlSerializer.Serialize(sw, t);
                return sw.ToString();
            }
        }
 
        /// <summary>
        /// XML反序列化为对象
        /// </summary>
        /// <typeparam name="T">对象类型</typeparam>
        /// <param name="xml">xml字符串</param>
        /// <returns></returns>
        public static T Deserialize<T>(string xml)
        {
            XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
            StringReader stringReader = new StringReader(xml);
            return (T)xmlSerializer.Deserialize(stringReader);
        }
 
    }
}

XmlTypeAttribute类

该类主要控制当属性目标由XML序列化时生成的XML节点。

应用示例

/// <summary>
/// Envelope
/// </summary>
[XmlType(TypeName = "envelope")]
public class CityRes
{
    public Header header { get; set; }
    public Response response { get; set; }
}

/// <summary>
/// Envelope
/// </summary>
public class CityRes
{
    /// <summary>
    /// header
    /// </summary>
    [XmlElement("header")]
    public Header header { get; set; }
 
    /// <summary>
    /// response
    /// </summary>
    [XmlElement("response")]
    public Response response { get; set; }
 
}

/// <summary>
/// Version
/// </summary>
public class Version
{
    /// <summary>
    /// port
    /// </summary>
    [XmlAttribute("port")]
    public string port { get; set; }
 
    /// <summary>
    /// host
    /// </summary>
    [XmlAttribute("host")]
    public string host { get; set; }
 
    /// <summary>
    /// text
    /// </summary>
    [XmlAttribute("text")]
    public string text { get; set; }
}

[XmlArray]
public Item []Items
{
   get{return items;}
   set{items = value;}
}

[System.Xml.Serialization.XmlTextAttribute()]
public string[] Text
{
    get
    {
        return this.textField;
    }
    set
    {
        this.textField = value;
    }
}
