求C＃快速高效读取xml方法

如题，谢谢各位！

---

C# code:

private DataSet ConvertXmlToDataSet(string xmlPath)
{
DataSet mySet = new DataSet();
XmlDocument xdoc = new XmlDocument();
xdoc.Load(xmlPath);
XmlNodeReader reader = new XmlNodeReader(xdoc);
mySet.ReadXml(reader);
return mySet;
}

只是快速，不高效

反序列化...

using System;
using System.Xml;

namespace ReadXMLfromFile
{
    class Class1
    {
        static void Main(string[] args)
        {
            XmlTextReader reader = new XmlTextReader ("books.xml");
            while (reader.Read())
            {
                switch (reader.NodeType)
                {
                    case XmlNodeType.Element: // The node is an element.
                        Console.Write(" <" + reader.Name);
