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>

/// 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

}
