There are several strategies to read an XML document, or parts thereof, using C#. If you are more specific about what you want to do with the XML document, the community can provide you with more specific guidance.

以下是一些最好的选择:

How about just LINQ to XML?

只需要LINQ to XML怎么样?

Given this:

鉴于这种:

var xml = "<ss:demo>\r\n<ss:Name>\r\n    <ss:FirstName>First</ss:FirstName>\r\n    <ss:SecondName>" +
"Second</ss:SecondName>\r\n</ss:Name>\r\n<ss:country code=\"IN\">India</ss:country>\r\n</ss" +
":demo>";

(Note I had to wrap IN in quotes as such "IN")

(注意，我必须用“IN”这样的引号括起来)

Declare some namespaces and read it in:

声明一些名称空间并将其读入:

var mngr = new XmlNamespaceManager( new NameTable() );
mngr.AddNamespace( "ss", "urn:ignore" ); // or proper URL
var parserContext = new XmlParserContext(null, mngr, null, XmlSpace.None, null);

If reading from a string as above:

如果从上面的字符串中读取:

var txtReader = new XmlTextReader( xml, XmlNodeType.Element, parserContext );

If reading from a file instead:

如果从文件中读取，则改为:

var txtReader = new XmlTextReader( new FileStream(filename, FileMode.Open), XmlNodeType.Element, parserContext );

Then load:

然后加载:

var ele = XElement.Load( txtReader );

ele contains everything you need.
