下面是我写的一个读取xml站点地图的应用程序:

using System;
using System.Collections.Generic;
using System.Windows.Forms; 
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using System.Data;
using System.Xml;

namespace SiteMapReader
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Please Enter the Location of the file");

            // get the location we want to get the sitemaps from 
            string dirLoc = Console.ReadLine();

            // get all the sitemaps 
            string[] sitemaps = Directory.GetFiles(dirLoc);
            StreamWriter sw = new StreamWriter(Application.StartupPath + @"\locs.txt", true);

            // loop through each file 
            foreach (string sitemap in sitemaps)
            {
                try
                {
                    // new xdoc instance 
                    XmlDocument xDoc = new XmlDocument();

                    //load up the xml from the location 
                    xDoc.Load(sitemap);

                    // cycle through each child noed 
                    foreach (XmlNode node in xDoc.DocumentElement.ChildNodes)
                    {
                        // first node is the url ... have to go to nexted loc node 
                        foreach (XmlNode locNode in node)
                        {
                            // thereare a couple child nodes here so only take data from node named loc 
                            if (locNode.Name == "loc")
                            {
                                // get the content of the loc node 
                                string loc = locNode.InnerText;

                                // write it to the console so you can see its working 
                                Console.WriteLine(loc + Environment.NewLine);

                                // write it to the file 
                                sw.Write(loc + Environment.NewLine);
                            }
                        }
                    }
                }
                catch { }
            }
            Console.WriteLine("All Done :-)"); 
            Console.ReadLine(); 
        }

        static void readSitemap()
        {
        }
    }
}

有很多方法，一些:

XmlSerializer。使用带有目标模式的类 如果您想读取，请使用XmlSerializer 将Xml中的数据加载到 类的实例。 linq2xml XmlTextReader。 XmlDocument XPathDocument(只读访问)

Linq到XML。

同时,VB。NET通过编译器提供了比c#更好的xml解析支持。如果你有这个选择和愿望，那就去看看吧。

There are different ways, depending on where you want to get. XmlDocument is lighter than XDocument, but if you wish to verify minimalistically that a string contains XML, then regular expression is possibly the fastest and lightest choice you can make. For example, I have implemented Smoke Tests with SpecFlow for my API and I wish to test if one of the results in any valid XML - then I would use a regular expression. But if I need to extract values from this XML, then I would parse it with XDocument to do it faster and with less code. Or I would use XmlDocument if I have to work with a big XML (and sometimes I work with XML's that are around 1M lines, even more); then I could even read it line by line. Why? Try opening more than 800MB in private bytes in Visual Studio; even on production you should not have objects bigger than 2GB. You can with a twerk, but you should not. If you would have to parse a document, which contains A LOT of lines, then this documents would probably be CSV.

我写这条评论，是因为我看到了大量使用XDocument的示例。XDocument不适用于大型文档，或者当您只想验证内容是否为XML有效时。如果希望检查XML本身是否有意义，那么需要Schema。

我对建议的答案也投了反对票，因为我相信它本身就需要上述信息。假设我需要验证200M的XML是否有效，每小时10次。XDocument会浪费大量的资源。

prasanna venkatesh还指出，您可以尝试将字符串填充到数据集，它也将指示有效的XML。
