篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了xml对象的序列化和反序列化相关的知识,希望对你有一定的参考价值。
对象序列化:
/// <summary>
/// 将一个对象序列化为XML字符串
/// </summary>
/// <param name="o">要序列化的对象</param>
/// <param name="encoding">编码方式</param>
/// <returns>序列化产生的XML字符串</returns>
public static string XmlSerialize(object o, Encoding encoding)
{
using (MemoryStream stream = new MemoryStream())
{
XmlSerializeInternal(stream, o, encoding);
stream.Position = 0;
using (StreamReader reader = new StreamReader(stream, encoding))
{
return reader.ReadToEnd();
}
}
}
private static void XmlSerializeInternal(Stream stream, object o, Encoding encoding)
{
if (o == null)
throw new ArgumentNullException("o");
if (encoding == null)
throw new ArgumentNullException("encoding");
XmlSerializer serializer = new XmlSerializer(o.GetType(), string.Empty);
XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = false;
//settings.NewLineChars = "\r\n";
settings.Encoding = encoding;
settings.IndentChars = " ";
using (XmlWriter writer = XmlWriter.Create(stream, settings))
{
var ns = new XmlSerializerNamespaces();
ns.Add(string.Empty, string.Empty);
serializer.Serialize(writer, o, ns);
writer.Close();
}
}
对象反序列化:
/// <summary>
/// 从XML字符串中反序列化对象
/// </summary>
/// <typeparam name="T">结果对象类型</typeparam>
/// <param name="s">包含对象的XML字符串</param>
/// <param name="encoding">编码方式</param>
/// <returns>反序列化得到的对象</returns>
public static T XmlDeserialize<T>(string s, Encoding encoding) where T : class
{
try
{
if (string.IsNullOrEmpty(s))
throw new ArgumentNullException("s");
if (encoding == null)
throw new ArgumentNullException("encoding");
XmlSerializer mySerializer = new XmlSerializer(typeof(T));
using (MemoryStream ms = new MemoryStream(encoding.GetBytes(s)))
{
using (StreamReader sr = new StreamReader(ms, encoding))
{
var temp = mySerializer.Deserialize(sr);
return (T)temp;
}
}
}
catch (Exception ex)
{
var log = new En.Debuger()
{
Channel = "CMB",
ActionName = "CMB_Refund",
LogText = ex.Message,
CreateTime = DateTime.Now
};
Da.Debuger.Add(Config.PaymentDatabase, log);
return null;
}
}
