我正在建立一个网站。现在我想创建像谷歌站点地图一样的xml站点地图。但我想用C#以编程方式创建它。

有人可以告诉我如何使用我的网站的基本网址访问网络服务器上的根目录,将所有网页列表转换为字符串列表吗?

我创建了这个库,可以很容易地从一个类或列出网址创建谷歌站点地图。

您可以看看此NuGet软件包(支持.Net和.Net Core) https://www.nuget.org/packages/xsitemap/

class Program
{
    static void Main(string[] args)
    {
        var sitemap = new Sitemap();

        sitemap.Add(new Url
        {
            ChangeFrequency = ChangeFrequency.Daily,
            Location = "http://www.example.com",
            Priority = 0.5,
            TimeStamp = DateTime.Now
        });

        sitemap.Add(CreateUrl("http://www.example.com/link1"));
        sitemap.Add(CreateUrl("http://www.example.com/link2"));
        sitemap.Add(CreateUrl("http://www.example.com/link3"));
        sitemap.Add(CreateUrl("http://www.example.com/link4"));
        sitemap.Add(CreateUrl("http://www.example.com/link5"));


        //Save sitemap structure to file
        sitemap.Save(@"d:\www\example.com\sitemap.xml");

        //Split a large list into pieces and store in a directory
        sitemap.SaveToDirectory(@"d:\www\example.com\sitemaps");

        //Get xml-content of file
        Console.Write(sitemap.ToXml());

        Console.ReadKey();
    }

    private static Url CreateUrl(string url)
    {
        return new Url
        {
            ChangeFrequency = ChangeFrequency.Daily,
            Location = url,
            Priority = 0.5,
            TimeStamp = DateTime.Now
        };
    }
}

如果您的站点页面相互链接,并且普通用户可以浏览所有页面(页面内容中具有必要的链接),则可以递归创建站点网页列表并将其放入xml文件(遵守sitemap protocol的标准) 来自working app的网址列表生成器的代码段:

...
   new_urls.Add(BaseUrl);  //first url
   do
   {
      List hrefs=new List();
      foreach (var url in new_urls)
      {
         string text =await _loader.Get(url);
         if (string.IsNullOrEmpty(text)) continue;

         visited.Add(url);
         List meta=Parser.GetAHrefs(text).Distinct().ToList();  //getting list of links
         Parser.Normalize(Domain,url,ref meta);
         if (Exclude)  //option to exclude query from url
             meta = meta.Select(u => u.Contains('?') ? u.Split('?')[0] : u).ToList();
         hrefs.AddRange(meta);
         hrefs = hrefs.Distinct().ToList();
       }
       new_urls = hrefs.Except(visited).ToList();   //excluding visited pages
    }
    while (new_urls.Count != 0);
...

平原text to xml parsing method

public void Save(string path)
        {
            string doc = "<?xml version=\"1.0\" encoding=\"UTF - 8\"?>";

            doc += OpenTag("urlset", "xmlns=\"http://www.sitemaps.org/schemas/sitemap/0.9\"");

            if (UseOpt)
            {
                foreach (var url in Urls)
                {
                    doc += OpenTag("url");
                    doc += Tag("loc", url);
                    doc += Tag("lastmod", LastMode);
                    doc += Tag("changefreq", Changefreq);
                    doc += Tag("priority", Priority);
                    doc += CloseTag("url");
                }
            }
            else
            {
                foreach(var url in Urls)
                {
                    doc += OpenTag("url");
                    doc += Tag("loc", url);
                    doc += CloseTag("url");
                }
            }

            doc += CloseTag("urlset");

            File.WriteAllText(path,doc);
        }
