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.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.Close();

this._name = nameValue;

this._age = ageValue;

}
