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 );
