乱舞WindowsPhone——xml文件读取

Windows Phone中的xml文件不能像传统.net中通过XmlDocument进行操作，以下介绍几种常用的xml操作方式：

1：通过Linq to Xml读取xml  (Resource)

首先创建用于测试的xml文件，并将该文件的生成操作设置为Resource,创建对应的实体类;

<?xml version="1.0"?>
<Root>
    <LoginRequest>
        <Uid>yonghu1</Uid>
        <Password>123456</Password>
    </LoginRequest>
    <LoginRequest>
        <Uid>yonghu2</Uid>
        <Password>123456</Password>
    </LoginRequest>
    <LoginRequest>
        <Uid>yonghu3</Uid>
        <Password>123456</Password>
    </LoginRequest>
</Root>

 

public class LoginRequest
    {
        public String Uid { get; set; }
        public String Password { get; set; }
    }

 

其次引用System.Xml.Linq;

var stream = Application.GetResourceStream(new Uri("/BlogTest;component/xml/Login.xml", UriKind.Relative));
            XElement element = XElement.Load(stream.Stream);
            var loginList = (from el in element.Descendants("LoginRequest")
                        select new LoginRequest
                                   {
                                       Uid = el.Element("Uid").Value,
                                       Password = el.Element("Password").Value
                                   }).ToArray();

2：通过XmlReader方式读取xml

这种方法通过比对节点Name以及节点NodeType来寻找自己需要解析的内容

var reader = XmlReader.Create(stream.Stream);
            var loginList = new List<LoginRequest>();
            while (reader.Read())
            {
                if(reader.NodeType==XmlNodeType.Element)
                {
                    if(reader.Name=="LoginRequest")
                    {
                        var loginRequest = new LoginRequest();
                        while (reader.Read() && reader.NodeType!=XmlNodeType.EndElement)
                        {
                            if(reader.Name=="Uid")
                            {
                                if(reader.Read())
                                {
                                    loginRequest.Uid = reader.Value;
                                }
                            }
                        }
                        while (reader.Read() && reader.NodeType != XmlNodeType.EndElement)
                        {
                            if (reader.Name == "Password")
                            {
                                if (reader.Read())
                                {
                                    loginRequest.Password = reader.Value;
                                }
                            }
                        }
                        loginList.Add(loginRequest);
                    }
                }
            }

3：反序列化方式获取xml

这种方式常用于读取保存后的序列化xml文件，见以下链接：
