.NET FCL提供了与XML解析相关的不同内容。这是我对他们的简短概述：

Different approached to XML parsing are offered by .NET FCL. This is my short overview of them:

1. 使用 System.Xml.XmlDocument class。它实现了DOM接口;如果文档的大小不是太大，这种方式是最简单和最好的。
   参见 http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx [ ^ ]。
2. 使用类 System.Xml.XmlTextReader ;这是最快的阅读方式，特别是你需要跳过一些数据。
   参见 http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.aspx [ ^ ]。
3. 使用类 System.Xml.Linq.XDocument ;这是类似于 XmlDocument 的最合适的方式，支持LINQ to XML Programming。
   参见 http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx [ ^ ]，http://msdn.microsoft.com/en-us/library/bb387063.aspx [ ^ ]。

1. Use System.Xml.XmlDocument class. It implements DOM interface; this way is the easiest and good enough if the size if the document is not too big.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx[^].
2. Use the class System.Xml.XmlTextReader; this is the fastest way of reading, especially is you need to skip some data.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.aspx[^].
3. Use the class System.Xml.Linq.XDocument; this is the most adequate way similar to that of XmlDocument, supporting LINQ to XML Programming.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx[^], http://msdn.microsoft.com/en-us/library/bb387063.aspx[^].

这里是简单的解决方案创建类BasicSetup

here is simple solution create class BasicSetup

class BasicSetup
       {
           public string HeadId { get; set; }
           public string Amount { get; set; }
       }

这里是读取xml对象的代码< br $>

and here is code to read xml object

string path = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location) + "\\XMLData.xml";
            XDocument objXML = XDocument.Load(path);
            List<BasicSetup> objPARAMS = (from b in objXML.Descendants("BasicSetup")
                            select new BasicSetup()
                            {
                                HeadId =  b.Attribute("HeadId").Value,
                                Amount = b.Attribute("Amount").Value
                            }).ToList<BasicSetup>();


            foreach(BasicSetup obj in objPARAMS )
            {
                Console.WriteLine(String.Format("HeadId : {0} and Amount : {1}.", obj.HeadId,obj.Amount));
            }
