XML序列化与反序列化

C#对于XML的序列化与反序列化提供了很好的支持，我们只需要引用System.Xml的命名空间即可，无需使用第三方库，下面简单实现了一个XML的序列化与反序列化的帮助类。

using System;
using System.IO;
using System.Text;
using System.Xml;
using System.Xml.Serialization;

namespace XmlHelper
{
    public static class XmlSerializeHelper
    {
        /// <summary>
        /// XML序列化
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="obj"></param>
        /// <returns></returns>
        public static string XmlSerializer<T>(T obj)
        {          
            var settings = new XmlWriterSettings
            {
                Encoding = new UTF8Encoding(false),
                Indent = true
            };

            using (var ms = new MemoryStream())
            {                           
                using (var xw = XmlWriter.Create(ms, settings))
                {
                    var ns = new XmlSerializerNamespaces();
                    ns.Add("", "");
                    var serializer = new XmlSerializer(obj.GetType());
                    serializer.Serialize(xw, obj, ns);
                    return Encoding.UTF8.GetString(ms.ToArray());
                }
            }
        }

        /// <summary>
        /// XML反序列化
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="XmlString"></param>
        /// <returns></returns>
        public static T XmlDeserialize<T>(this string XmlString)
        {
            if (string.IsNullOrEmpty(XmlString))
                throw new ArgumentNullException("s");         

            using (var ms = new MemoryStream(Encoding.UTF8.GetBytes(XmlString)))
            {
                using (var xr = XmlReader.Create(ms))
                {
                    var xmlSerializer = new XmlSerializer(typeof(T));
                    return (T)xmlSerializer.Deserialize(xr);
                }
            }
        }

    }
}
