关于C#输出xml的问题

再一次来发帖求帮助……本人希望通过c#可以输出入上面的xml，搜了几个例子依样画瓢了一下，生成了下面的xml，发现有很多地方不对。希望高手能帮本人指正一下。主要是在使用SetAttirbute的时候，rdf:ID 之类的输出不正确。请高手帮本人看一下。关于C#输出xml的问题

代码如下。

解决方案

xmlsub1.SetAttribute(“ID”, “http://www.w3.org/1999/02/22-rdf-syntax-ns#”, “_28159176D77E2467″);
原理解析：
<rdf:RDF xml:base=”nari” xmlns:rdf=”http://www.w3.org/1999/02/22-rdf-syntax-ns#”
开头有设置rdf命名空间，则后面SetAttribute时，会寻找已有的命名空间，假如存在，则把别名放在前缀，例如 rdf:
否则会变成
<cim:Substation d2p1:ID=”_28159176D77E2467″ rdf:ID1=”111111111111111″ xmlns:d2p1=”未引入的命名空间”>
本人感受下吧。
