asp.net XML转JSON

先用Linq查询XML节点,再转换成List或Model,再用Json.NET转为Json

好处是可以随时返回List

XML

<?xml version="1.0" encoding="utf-8" ?>
    <Users>
        <User ID="111111">
        <name>EricSun</name>
        <password>123456</password>
        <description>Hello I'm from Dalian</description>
    </User>
    <User ID="222222">
        <name>Ray</name>
        <password>654321</password>
        <description>Hello I'm from Jilin</description>
        </User>
    </Users>
