我尝试了一些与此错误相关的帖子,但没有运气,我也尝试使用 xmlDocument 但无法获取InResponseTo的值。任何帮助深表感谢。
方法1(没用)
var xdoc = XDocument.Load("samlresponse.xml");
var items = from i in xdoc.Descendants("saml:SubjectConfirmationData")
select new
{
Recipient = (string)i.Attribute("InResponseTo")
};
方法2(没用)
XmlDocument xmlDocument = new XmlDocument();
xmlDocument.Load("samlresponse.xml");
var SubjectConfirmationnodes = xmlDocument.SelectNodes(@"//saml:Subject/saml:SubjectConfirmation");
解决方案
获取价值
XmlNodeList nodeList = xmlDocument.GetElementsByTagName("saml:SubjectConfirmationData");
var InResponseTo = nodeList[0].Attributes[2].Value;
