XmlWriter/XmlReader示例代码

在Silverlight项目中，如果您想最大程度的减少xap包的大小，仅使用默认System.Xml命名空间下提供的功能来实现“XML序列化/反序列化”，恐怕XmlReader/XmlWriter将成为唯一选择了，下面是示例代码：

using System.IO; using System.Text; using System.Xml;    namespace slLib {      public class Person      {          private string _name = "" ;             /// <summary>          /// 姓名          /// </summary>          public string Name          {              get { return _name; }              set { _name = value; }          }                private int _age = 0;             /// <summary>          /// 年龄          /// </summary>          public int Age                  {              get { return _age; }              set { _age = value; }          }             /// <summary>          /// 将Person实例转化为xml字符串          /// </summary>          /// <returns></returns>          public string ToXmlString()           {              MemoryStream ms = new MemoryStream();              XmlWriter writer = XmlWriter.Create(ms);                 writer.WriteStartDocument();                  writer.WriteStartElement( "data" );                      writer.WriteStartElement( "person" );                                                                           writer.WriteStartElement( "name" );                                                     writer.WriteAttributeString( "type" , "String" );                              writer.WriteValue( this .Name);                          writer.WriteEndElement();                             writer.WriteStartElement( "age" );                              writer.WriteAttributeString( "type" , "Int32" );                              writer.WriteValue( this .Age);                          writer.WriteEndElement();                         writer.WriteEndElement();                  writer.WriteEndElement();              writer.WriteEndDocument();                 writer.Flush();              writer.Close();              byte [] bytes = ms.ToArray();              string result = Encoding.UTF8.GetString(bytes, 0, bytes.Length);              return result;          }             /// <summary>          /// 从xml字符串给Person实例属性赋值          /// </summary>          /// <param name="xmlString"></param>          public void FromXmlString( string xmlString)           {              MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(xmlString));              XmlReader reader = XmlReader.Create(ms);                               reader.Read();              reader.ReadStartElement( "data" );                  reader.ReadStartElement( "person" );                      string nameType = reader.GetAttribute( "type" );                      string nameValue = reader.ReadElementContentAsString();                      string ageType = reader.GetAttribute( "type" );                      int ageValue = reader.ReadElementContentAsInt();                  reader.ReadEndElement();              reader.ReadEndElement();              reader.Close();                 this ._name = nameValue;              this ._age = ageValue;                            }                    } }
