C#操作xml哪种方式性能比较高

Question

如javascript 、linq to xml、xmldocument等 

Answer 1

个人觉得js好点！     js不用依赖。net库！            

Answer 2

js不知道。C#方面，应该XmlReader比较快吧，毕竟是SAX的实现。
XDocument（Linq to XML) 和XmlDocument都是DOM，估计差不多。XmlSerializer是最慢的，好像用到了动态编译。

Answer 3

SAX是比较快，不用把整个文件加载到内存，但是不支持随机访问。Dom把文档加载到内存中，耗费资源，但是可以随机访问

Answer 4

基本还是使用XMLReader，XmlDom与Linq to Xml比，Linq to XML还是要好一些

Answer 5

XMLReader 性能是最高的。现在读自定义配置文件我都用XMLReader了。

Answer 6

js xmldocument 都可以,看你要怎样的处理
