一个可序列化的C#对象，如何转成一个XML格式的文件或字符串【转】

原文：http://blog.csdn.net/otong/article/details/7894059

序列化或反序列化成一个字符串：

方法一：

序列化：

public static string XMLSerialize<T>(T entity)
       {
           StringBuilder buffer = new StringBuilder();

           XmlSerializer serializer = new XmlSerializer(typeof(T));
           using (TextWriter writer = new StringWriter(buffer))
           {
               serializer.Serialize(writer, entity);
           }

           return buffer.ToString();

       }

反序列化：

public static T DeXMLSerialize<T>(string xmlString)
        {
            T cloneObject = default(T);

            StringBuilder buffer = new StringBuilder();
            buffer.Append(xmlString);

            XmlSerializer serializer = new XmlSerializer(typeof(T));

            using (TextReader reader = new StringReader(buffer.ToString()))
            {
                Object obj = serializer.Deserialize(reader);
                cloneObject = (T)obj;
            }

            return cloneObject;
        }

方法二：

/// <summary>
    /// 对象序列化成 XML String
    /// </summary>
    public static string XmlSerialize<T>(T obj)
    {
        string xmlString = string.Empty;
        XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
        using (MemoryStream ms = new MemoryStream())
        {
            xmlSerializer.Serialize(ms, obj);
            xmlString = Encoding.UTF8.GetString(ms.ToArray());
        }
        return xmlString;
    }

    /// <summary>
    /// XML String 反序列化成对象
    /// </summary>
    public static T XmlDeserialize<T>(string xmlString)
    {
        T t = default(T);
        XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
        using (Stream xmlStream = new MemoryStream(Encoding.UTF8.GetBytes(xmlString)))
        {
            using (XmlReader xmlReader = XmlReader.Create(xmlStream))
            {
                Object obj = xmlSerializer.Deserialize(xmlReader);
                t = (T)obj;
            }
        }
        return t;
    }

如果要序列化到一个文件，则使用FileStream就可以了

如：

string strFile = @"c:/book.xml";
            using (FileStream fs = new FileStream(strFile, FileMode.Create))
            {
                XmlSerializer formatter = new XmlSerializer(typeof(T));
                formatter.Serialize(fs, entity);
            }

附：其实还可以直接用SringWriter

StringBuilder sb = new StringBuilder();
System.IO.StringWriter writer = new System.IO.StringWriter(sb);

XmlSerializer formatter = new XmlSerializer(typeof(T));
formatter .Serialize(writer,entity );
