刚开始学WPF真不知道从哪里开始，就想着每次学什么东西好像都是先写个留言板，嘿嘿，今天就做了个操作XML数据，实现增删，及排序功能。由于是菜鸟所以代码很乱，只供自己以后查看。

<?xml version="1.0" encoding="utf-8"?>
<Persons>
  <Person>
    <name>杨磊</name>
    <sex>男</sex>
    <year>22</year>
  </Person>
  <Person>
    <name>XX</name>
    <sex>MM</sex>
    <year>10</year>
  </Person>
  <Person>
    <name>YY</name>
    <sex>GG</sex>
    <year>34</year>
  </Person>
  <Person>
    <name>RR</name>
    <sex>GG</sex>
    <year>55</year>
  </Person>
  <Person>
    <name>WW</name>
    <sex>MM</sex>
    <year>18</year>
  </Person>
  <Porson>
    <name>ry</name>
    <sex>rtyu</sex>
    <year>45</year>
  </Porson>
</Persons>

可以优化的地方还望能提出来
