好吧，你可以用正则表达式去掉你不需要的所有东西
XElement d = XElement.Parse(feed); // load the feed in an XElement
// get the title, link and description
string title = d.Elements("title").FirstOrDefault().Value;
string link = d.Elements("link").FirstOrDefault().Value;
string description = d.Elements("description").FirstOrDefault().Value;
// remove everything that's between '<>'
Regex r = new Regex(@"<.*>");
description = r.Replace(description, "");
XElement d=XElement.Parse（feed）；//在XElement中加载提要
//获取标题、链接和描述
字符串title=d.Elements（“title”）.FirstOrDefault（）值；
字符串link=d.Elements（“link”）.FirstOrDefault（）值；
字符串描述=d.Elements（“描述”）.FirstOrDefault（）值；
//删除介于“”之间的所有内容
正则表达式r=新正则表达式（@“”）；
description=r.替换（description，“”）；
第二轮比赛的结果是：圣安东尼奥马刺队在上半场落后三分，以93-87的比分与孟菲斯灰熊队以1-1的比分扳平季后赛首轮比赛。第一轮比赛结果不变，第三轮比赛将自动忽略所有CDATA内容。好吧，你可以使用一个正则表达式，用来处理所有你不需要的东西
XElement d = XElement.Parse(feed); // load the feed in an XElement
// get the title, link and description
string title = d.Elements("title").FirstOrDefault().Value;
string link = d.Elements("link").FirstOrDefault().Value;
string description = d.Elements("description").FirstOrDefault().Value;

对于第二轮比赛，结果将是：圣安东尼奥马刺队在半场时落后三分，以93-87的比分与孟菲斯灰熊队以1-1的比分扳平季后赛首轮系列赛。第一轮比赛结果将保持不变，第三轮比赛将自动忽略所有CDATA内容。不太确定，但我不确定如果编码的HTML是收到的CDATA描述的一部分，则上述正则表达式将不起作用。您可能需要先使用描述的
