我試圖讓媒體的網址值：內容，當我通過聯合項目環像這樣：

  foreach (SyndicationItem item in feed.Items) 
      { 

       foreach (SyndicationElementExtension extension in item.ElementExtensions) 
       { 
        XElement ele = extension.GetObject<XElement>(); 
        MessageBox.Show(ele.Value); 
       } 


      }

我得到的空白數據，我怎樣才能得到媒體內容的網址？

你需要獲得的屬性不是元素的值，你應該檢查該媒體內容。 – loneshark99

而不是'ele.Value'你試過'ele.Attribute（「url」）？ – wal

你嘗試過：

XElement ele = extension.GetObject<XElement>(); 
if (ele.Name.LocalName == "content") 
{ 
    MessageBox.Show(ele.Attribute("url").Value); 
}

一個建議：使用'（串）ele.Attribute（「URL」）對'ArgumentNullExceptions'的情況下'Value'財產守衛在那裏的屬性未聲明的'isntead。 –
