我正在建立一个网站。现在我想创建它的 xml 站点地图，如谷歌站点地图。但我想使用 C# 以编程方式创建它。
谁能告诉我如何使用我网站的基本 url 访问 web 服务器上的根目录，将所有页面列表放入一个字符串列表中？

如果您的网站页面相互链接并且普通用户可以浏览所有页面（在页面内容中有必要的链接），则可以递归地创建网站网页列表并将其放入 xml 文件（遵守sitemap protocol的标准） 来自working app的url列表生成器的代码sn-p：
...
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);
...
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);
}

你可以看看这个 NuGet 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
};
}
}

我已经制作了这个库，它可以很容易地从一个类创建谷歌站点地图或列出一个 url。
