Answer 1

您可以尝试Linq Xml读取xml文档并提取元素值。

 XDocument doc = XDocument.Load(file);
 var result = doc.Root.Element("links").Element("original").Value;

Answer 2

XmlDocument xml = new XmlDocument();
xml.LoadXml(myXmlString); // your XML String

XmlNodeList xnList = xml.SelectNodes("/upload/links");
foreach (XmlNode xn in xnList)
{
  string original= xn["original"].InnerText;
  string imgur_page = xn["imgur_page"].InnerText;
  string delete_page = xn["delete_page"].InnerText;
  string small_square = xn["small_square"].InnerText;
  string large_thumbnail= xn["large_thumbnail"].InnerText;


}
