Answer 1

这样的事可能吗？

XDocument doc = XDocument.Parse("<insert xml here or use variable>");
var username = doc.XPathSelectElement("/SomeNode/SomeOtherNode/@username").Value;
var id = doc.XPathSelectElement("/SomeNode/SomeOtherNode/@id").Value;

我知道你使用的是.NET 2.0，所以我在这个例子中使用了XmlDocument：

System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();
TwitterUser user = new TwitterUser();

string url = "http://api.twitter.com/1/account/verify_credentials.xml";
string xml = oAuth.oAuthWebRequest(oAuthTwitter.Method.GET, url, String.Empty);

xmlDoc.LoadXml(xml);

user.id = xmlDoc.SelectSingleNode("user/id").InnerText;
user.screen_name = xmlDoc.SelectSingleNode("user/screen_name").InnerText;
user.name = xmlDoc.SelectSingleNode("user/name").InnerText;
