Question

我正在为deserialize SAML xml开发解决方案。但面临一个错误说

“Issuer xmlns ='urn：oasis：names：tc：SAML：2.0：assertion'不是预期“

代码

        XmlNamespaceManager ns = new XmlNamespaceManager(SAMLXML.NameTable);
        ns.AddNamespace("saml", "urn:oasis:names:tc:SAML:2.0:assertion");

        XmlElement xeAssertion =  SAMLXML.DocumentElement.SelectSingleNode("saml:Assertion",ns) as XmlElement;

        AssertionType assertionType = new AssertionType();
        XmlSerializer serializer = new XmlSerializer(assertionType.GetType(),ns.DefaultNamespace);

        MemoryStream ms = new MemoryStream(Encoding.UTF32.GetBytes(xeAssertion.InnerXml.ToString()));
        ms.Position = 0;
        ms.Seek(0, SeekOrigin.Begin);

        AssertionType assertion = (AssertionType)serializer.Deserialize(ms);

        return assertion;

终于找到了解决方案

<强>代码

          XmlNamespaceManager ns = new XmlNamespaceManager(SAMLXML.NameTable);
            ns.AddNamespace("saml", "urn:oasis:names:tc:SAML:2.0:assertion");

            XmlElement xeAssertion = SAMLXML.DocumentElement.SelectSingleNode("saml:Assertion", ns) as XmlElement;


            string xml = null;
            var memoryStream = new MemoryStream();
            var serializer = new XmlSerializer(xeAssertion.GetType());
            var streamWriter = new StreamWriter(memoryStream, Encoding.UTF8);
            serializer.Serialize(streamWriter, xeAssertion);
            memoryStream = (MemoryStream)streamWriter.BaseStream;

            xml = memoryStream.ToArray().Utf8ByteArrayToString();


            var serializer = new XmlSerializer(typeof(AssertionType));
            var memoryStream = new MemoryStream(xml.StringToUtf8ByteArray());


             AssertionType assertion = (AssertionType)serializer.Deserialize(memoryStream);

             return assertion;
