解析xml

weimei521 2018-06-20 02:32:05

<?xml version=”1.0” encoding=” gbk”?>
<Pay>
<response>
<Header>
<funid> YLPAY.01.01.01</funid>
<sign>0000000000000000 </sign>
<result>0</result>
<errmsg></errmsg>
</Header>
<Body>
<amount>100</amount>
<pos_serial>123123123</pos_serial>
<pos_trade_date>2018-06-20</pos_trade_date>
</Body>
</ response >
</Pay>
自己写的方法如下：
XmlDocument xd = new XmlDocument();
xd.LoadXml(XML);
XmlNamespaceManager xnm = new XmlNamespaceManager(xd.NameTable);
XmlNodeList xnl = xd.SelectNodes("/pay/response/Body", xnm);
foreach (XmlElement xe in xnl)
{
//获取节点数据
}
但是这样就属于如果要解析很多，不能写一个公用的方法，请教大神有没有公用的方法

直接操作xml本来就是定制性比较强的东东，不管是原生的xmldoc方式，还是linq2xml方式但反序列化说白了只是提取了将xml转化成实体这个过程，你获取/pay/response/Body的过程仍然要写成 entity.Response.Body，对于其他xml，你可能就要写成xxx.YYY，这种虽然写法上干净明了，但额外的你需要多定义相应的实体类所以如果不是需要将xml进行传递，只是需要解析的话，个人建议还是用linq2xml的方式

Linq to XML 这可能是更快更好的选择

在vs里编辑--选择性粘贴--把xml粘贴为类结果是

在去百度标准的“C# xml反序列化对象”就好。剩下的事情只是反序列化他，然后他就是一个Pay对象，你按对象访问就行
