C#实现Xml序列化与反序列化的方法
本文实例讲述了C#实现Xml序列化与反序列化的方法。分享给大家供大家参考。具体实现方法如下：
/// <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>

/// <param name="obj">对象</param>
/// <returns></returns>
public static string Serializer<T>(T obj)
{
return Serializer(typeof(T), obj);
}
/// <summary>

/// <param name="type">类型</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
}
