xml反序列化
有xml格式如下
<reqdata>
<user>admin</user>
<message>
<xml>
<a>sd</a>
<b>sd</b>
</xml>
</message>
</reqdata>
c#类代码如下，我在把xml反序列化成字典的时候，像把message节点里的<xml><a>sd</a><b>sd</b></xml>这段当成message的值，请问代码该怎么改

如果我做的话，我会这样做：1.定义一个字符串变量。
2.把message的子节点取出来赋给变量，然后在循环子节点，循环一次就在变量的基础上增加一次。
3.最后message的值就取变量的值。
补充：.NET技术 , ASP.NET
