xmlreader.create返回none

Question

 String xmlString =
            @"<?xml version='1.0'?>
        <Items>
          <Item>test</Item>
        </Items>";
            // Create an XmlReader
            using (XmlReader reader = XmlReader.Create(new StringReader(xmlString)))
            {
                int aa = 0;
            }

或者metro下(XmlReader reader = XmlReader.Create(Stream))

两种情况下reader 总是none，这是为什么？

Answer 1

你上面写的没有错，它是会返会none的，XmlReader定位在文档中第一个节点之前，你须要调用Read()方法来读取。参考：http://social.msdn.microsoft.com/Forums/en-US/xmlandnetfx/thread/794e8dcf-4b09-481c-8742-af46673dd8b3/

Answer 2

明白了

如果是有命名空间的xml，应该怎么read？ readcontentas吗？参数如何配置？
