c# - 如何从 FQL 枚举响应集

Question

var response = _facebookAPI.Fql.Query(String.Format("SELECT uid FROM event_member WHERE eid={0}", myevent));

我想将响应转换为

List<long> uids

Answer 1

假设返回的字符串是一个 XMLDocument:

var response = _facebookAPI.Fql.Query(String.Format("SELECT uid FROM event_member WHERE eid={0}", myevent));
XmlDocument doc = new XmlDocument(); 
doc.LoadXml(response); 
XmlNodeList uids = doc.GetElementsByTagName("uid"); 

var uids = new List<long>();
foreach (XmlNode node in uids)
{
      long id;
      if (long.TryParse(node.InnerText, out id))
      {
           uids.Add(id);
      }
 }
