這篇文章主要介紹了C#實現(xiàn)Xml序列化與反序列化的方法,將序列化與反序列化的方法封裝入一個類文件中,包含了較為詳盡的注釋說明,非常具有實用價值,需要的朋友可以參考下

本文實例講述了C#實現(xiàn)Xml序列化與反序列化的方法。分享給大家供大家參考。具體實現(xiàn)方法如下：

/// <summary>
/// Xml序列化與反序列化
/// </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">字節(jié)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">類型</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);
}

#region 序列化

}
/// <summary>

public static string Serializer(Type type, object obj)
{
    MemoryStream Stream = new MemoryStream();
    XmlSerializerNamespaces _name = new XmlSerializerNamespaces();
    _name.Add("", "");//這樣就去掉 attribute 里面的 xmlns:xsi 和 xmlns:xsd
    XmlWriterSettings xmlWriterSettings = new XmlWriterSettings();
    xmlWriterSettings.Encoding = new UTF8Encoding(false);//設置編碼,不能用Encoding.UTF8,會導致帶有BOM標記
    xmlWriterSettings.Indent = true;//設置自動縮進
    //xmlWriterSettings.OmitXmlDeclaration = true;//刪除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))
{
     //序列化對象
     xml.Serialize(xmlWriter, obj, _name);
}
    }
    catch (InvalidOperationException)
    {
throw;
    }
    return Encoding.UTF8.GetString(Stream.ToArray()).Trim();
