在.net中验证和读取xml文件的最简单方法？

using System;
using System.Xml;
using System.Xml.Linq;
using System.Xml.Schema;

class Program
{
    static void Main(string[] args)
    {
        string xml = @"<root>
                         <element1>Text1</element1>
                         <element2>Text2</element2>
                        </root>";

        XDocument xdoc = XDocument.Parse(xml);

        // 验证XML文件
        XmlReaderSettings settings = new XmlReaderSettings();
        settings.Schemas.Add(null, XmlReader.Create(new StringReader(XSD)));
        settings.ValidationType = ValidationType.Schema;
        settings.ValidationEventHandler += new ValidationEventHandler(ValidationEventHandler);

        XmlReader reader = XmlReader.Create(new StringReader(xml), settings);
        while (reader.Read()) ;

        // 读取XML文件
        XElement root = XElement.Parse(xml);
        XElement element1 = root.Element("element1");
        Console.WriteLine("Element1: " + element1.Value);

        XElement element2 = root.Element("element2");
        Console.WriteLine("Element2: " + element2.Value);
    }

    static void ValidationEventHandler(object sender, ValidationEventArgs e)
    {
        throw new ApplicationException("XML validation error: " + e.Message);
    }

    const string XSD = @"<xs:schema xmlns:xs='http://www.w3.org/2001/XMLSchema'>
                          <xs:element name='root'>
                            <xs:complexType>
                              <xs:sequence>
                                <xs:element name='element1' type='xs:string'/>
                                <xs:element name='element2' type='xs:string'/>
                              </xs:sequence>
                            </xs:complexType>
                          </xs:element>
                        </xs:schema>";
}
