文实例讲述了C#实现Xml序列化与反序列化的方法。具体实现方法如下:

 

代码如下:
/// <summary>
/// Xml序列化与反序列化
/// </summary>
public class XmlUtil
{
public static string GetRoot(string xml)
{
    XmlDocument doc = new XmlDocument();
    doc.LoadXml(xml.Replace("\r\n", "").Replace("\0", "").Trim());
    var e = doc.DocumentElement;
    return e.InnerText;
}

 

#region 反序列化
/// <summary>
/// 反序列化
/// </summary>
/// <param name="xml">XML字符串</param>
/// <returns></returns>
public static T Deserialize<T>(string xml)
{
    return (T)Deserialize(typeof(T), xml);
}
/// <summary>
/// 反序列化
/// </summary>
/// <param name="stream">字节流</param>
/// <returns></returns>
public static T Deserialize<T>(Stream stream)
{
    return (T)Deserialize(typeof(T), stream);
}
/// <summary>
/// 反序列化
/// </summary>
/// <param name="type">类型</param>
/// <param name="xml">XML字符串</param>
/// <returns></returns>
public static object Deserialize(Type type, string xml)
{
    try
    {
 xml = xml.Replace("\r\n", "").Replace("\0", "").Trim();
 using (StringReader sr = new StringReader(xml))
 {
     XmlSerializer xmldes = new XmlSerializer(type);
     return xmldes.Deserialize(sr);
 }
    }
    catch (Exception e)
    {
 return null;
    }
}
/// <summary>
/// 反序列化
/// </summary>
/// <param name="type"></param>
/// <param name="xml"></param>
/// <returns></returns>
public static object Deserialize(Type type, Stream stream)
{
    XmlSerializer xmldes = new XmlSerializer(type);
    return xmldes.Deserialize(stream);
}
#endregion
#region 序列化
/// <summary>
/// 序列化
/// </summary>
/// <param name="obj">对象</param>
/// <returns></returns>
public static string Serializer<T>(T obj)
{
    return Serializer(typeof(T), obj);
}
/// <summary>
/// 序列化
/// </summary>
/// <param name="type">类型</param>
/// <param name="obj">对象</param>
/// <returns></returns>
public static string Serializer(Type type, object obj)
{
    MemoryStream Stream = new MemoryStream();
    XmlSerializerNamespaces _name = new XmlSerializerNamespaces();
    _name.Add("", "");//这样就 去掉 attribute 里面的 xmlns:xsi 和 xmlns:xsd
    XmlWriterSettings xmlWriterSettings = new XmlWriterSettings();
    xmlWriterSettings.Encoding = new UTF8Encoding(false);//设置编码,不能用Encoding.UTF8,会导致带有BOM标记
    xmlWriterSettings.Indent = true;//设置自动缩进
    //xmlWriterSettings.OmitXmlDeclaration = true;//删除XmlDeclaration:<?xml version="1.0" encoding="utf-16"?>
    //xmlWriterSettings.NewLineChars = "\r\n";
    //xmlWriterSettings.NewLineHandling = NewLineHandling.None;
    XmlSerializer xml = new XmlSerializer(type);
    try
    {
 using (XmlWriter xmlWriter = XmlWriter.Create(Stream, xmlWriterSettings))
 {
     //序列化对象
     xml.Serialize(xmlWriter, obj, _name);
 }
    }
    catch (InvalidOperationException)
    {
 throw;
    }
    return Encoding.UTF8.GetString(Stream.ToArray()).Trim();
}
#endregion
}
