C#中xml操作

序列化成一个字符串：

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();

       } 

反序列化成对象：

    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;

            }  

利用MemoryStream的形式：

 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;

    }

  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;

    }  

生成文件：

string strFile = @"c:/zero.xml";

            using (FileStream fs = new FileStream(strFile, FileMode.Create))

            {

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

                formatter.Serialize(fs, entity);

            }

StringBuilder sb = new StringBuilder();

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

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

formatter .Serialize(writer,entity );
