如何在C#中读取和解析XML文件？

using System;
using System.IO;
using System.Xml;

public class XmlReaderExample
{
    public static void Main()
    {
        try
        {
            XmlReaderSettings settings = new XmlReaderSettings();
            settings.DtdProcessing = DtdProcessing.Parse;
            XmlReader reader = XmlReader.Create("example.xml", settings);
            while (reader.Read())
            {
                switch (reader.NodeType)
                {
                    case XmlNodeType.Element:
                        Console.WriteLine("Element: " + reader.Name);
                        break;
                    case XmlNodeType.Text:
                        Console.WriteLine("Text: " + reader.Value);
                        break;
                    case XmlNodeType.EndElement:
                        Console.WriteLine("End Element: " + reader.Name);
                        break;
                }
            }
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
        }
    }
}

using System;
using System.Xml.Linq;

public class LinqToXmlExample
{
    public static void Main()
    {
        try
        {
            XDocument doc = XDocument.Load("example.xml");
            var query = from item in doc.Descendants("item")
                        select new
                        {
                            Title = item.Element("title").Value,
                            Description = item.Element("description").Value
                        };
            foreach (var i in query)
            {
                Console.WriteLine("Title: {0}, Description: {1}", i.Title, i.Description);
            }
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
        }
    }
}
