如何在C#中导入原始RSS提要？

using System;
using System.ServiceModel.Syndication;
using System.Xml;
using System.Net;

class Program
{
    static void Main(string[] args)
    {
        string rssUrl = "https://www.example.com/rss";
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(rssUrl);
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        XmlReader reader = XmlReader.Create(response.GetResponseStream());
        SyndicationFeed feed = SyndicationFeed.Load(reader);

        Console.WriteLine("Title: " + feed.Title.Text);
        Console.WriteLine("Description: " + feed.Description.Text);

        foreach (SyndicationItem item in feed.Items)
        {
            Console.WriteLine("\nTitle: " + item.Title.Text);
            Console.WriteLine("Link: " + item.Link.Uri.ToString());
            Console.WriteLine("Published: " + item.PublishDate.ToString());
            Console.WriteLine("Summary: " + item.Summary.Text);
        }
    }
}
