我试图用这个例子来获取图像的URL从 HTTP：//www.nydailynews .COM / cmlink / NYDN.Article.rss

但没有成功。

ü可以帮助我找到正确的方式通过 SyndicationItem 类会从RSS源项目的所有可能的图片网址？

有解决办法草案here但我想应该更通用的解决方案。

感谢您！

 名单，其中，RssFeedItem＆GT;的RSSItems =新的名单，其中，RssFeedItem＆GT;（）;
                    流流= e.Result;
                    XmlReader的响应= XmlReader.Create（流）;
                    SyndicationFeed馈送= SyndicationFeed.Load（响应）;
                    的foreach（在feeds.Items SyndicationItem F）
                    {
                        RssFeedItem的RSSItem =新RssFeedItem（）;

                        rssItem.Description = f.Summary.Text;
的foreach（SyndicationLink圈地f.Links.Where＆LT; SyndicationLink＆GT;（X =＆GT; x.RelationshipType ==圈地））
                            {
                                乌里URL = enclosure.Uri;
                                长长度= enclosure.Length;
                                字符串mediaType的= enclosure.MediaType;
                                rssItem.ImageLinks.Add（url.AbsolutePath）;
                            }
}
 

解决方案

我找到了解决办法。

 的foreach（在f.ElementExtensions SyndicationElementExtension扩展）
{
    的XElement元= extension.GetObject＆LT;的XElement＆GT;（）;

    如果（element.HasAttributes）
    {
        的foreach（在element.Attributes var属性（））
        {
            字符串值= attribute.Value.ToLower（）;
            如果（value.StartsWith（HTTP：//，。巴，。GIF）及;＆安培（value.EndsWith（。JPG）|| value.EndsWith（）|| value.EndsWith（）） ）
            {
                   rssItem.ImageLinks.Add（值）; //此处添加图片链接到一些数组
             }
        }
    }
}
 

I try to use this example to get images urls from http://www.nydailynews.com/cmlink/NYDN.Article.rss

but no success

Could u help me to find all correct ways to gets all possible image URLs from RSS feed item by SyndicationItem class?

There is draft solution here but I guess should be more generic solution.

Thank you!

 List<RssFeedItem> rssItems = new List<RssFeedItem>();
                    Stream stream = e.Result;
                    XmlReader response = XmlReader.Create(stream);
                    SyndicationFeed feeds = SyndicationFeed.Load(response);
                    foreach (SyndicationItem f in feeds.Items)
                    {
                        RssFeedItem rssItem = new RssFeedItem();

                        rssItem.Description = f.Summary.Text;
foreach (SyndicationLink enclosure in f.Links.Where<SyndicationLink>(x => x.RelationshipType == "enclosure"))
                            {
                                Uri url = enclosure.Uri;
                                long length = enclosure.Length;
                                string mediaType = enclosure.MediaType;
                                rssItem.ImageLinks.Add(url.AbsolutePath);
                            }
}

I found the solution.

foreach (SyndicationElementExtension extension in f.ElementExtensions)
{
    XElement element = extension.GetObject<XElement>();

    if (element.HasAttributes)
    {
        foreach (var attribute in element.Attributes())
        {
            string value = attribute.Value.ToLower();
            if (value.StartsWith("http://") && (value.EndsWith(".jpg") || value.EndsWith(".png") || value.EndsWith(".gif") ))
            {
                   rssItem.ImageLinks.Add(value); // Add here the image link to some array
             }
        }                                
    }                            
}
