我已经创建了一个 SamlAssertion 的实例，并向其中添加了授权声明和属性声明，现在我想打印出 XML，以便我可以进行 HTTP 发布，但并不是所有的断言都被输出。我错过了什么（我确定这是一些愚蠢的东西）？

这是我正在使用的代码：

// Add the Statements to the SAML Assertion
   samlAssert.Statements.Add(samlAuthStatement);
   samlAssert.Statements.Add(samlAttrStatement);
   MemoryStream xmlStream = new MemoryStream();
   XmlDictionaryWriter xmlWriter = XmlDictionaryWriter.CreateTextWriter(xmlStream, System.Text.Encoding.UTF8);
   SamlSerializer samlAssertSerializer = new SamlSerializer();
   WSSecurityTokenSerializer secTokenSerializer = new WSSecurityTokenSerializer();
   samlAssert.WriteXml(xmlWriter, samlAssertSerializer, secTokenSerializer);

   xmlStream.Position = 0;
   StreamReader sr = new StreamReader(xmlStream, System.Text.Encoding.UTF8);
   string AssertStr = sr.ReadToEnd();
   TextBox1.Text = AssertStr;

但得到的只是这样的：

<saml:Assertion MajorVersion="1" MinorVersion="1" AssertionID="assertID" 
                Issuer="my Company" IssueInstant="2008-11-19T19:54:12.191Z" 
                xmlns:saml="urn:oasis:names:tc:SAML:1.0:assertion">
    <saml:Conditions NotBefore="2008-11-19T19:54:12.191Z" NotOnOrAfter="2008-11-19T19:59:12.191Z"/>
    <saml:AuthenticationStatement AuthenticationMethod="urn:oasis:names:tc:SAML:2.0:ac:classes:TimeSyncToken" 
                                  AuthenticationInstant="2008-11-19T19:54:12.191Z">
        <saml:Subject>
            <saml:NameIdentifier Format="cs-sstc-schema-assertion-1.1.xsd" NameQualifier="My company">xxxx</saml:NameIdentifier>
            <saml:SubjectConfirmation>
                <saml:ConfirmationMethod>urn:oasis:names:tc:SAML:1.0:cm:bearer</saml:ConfirmationMethod>
            </saml:SubjectConfirmation>
        </saml:Subject>
        <saml:SubjectLocality IPAddress="x.x.x.x"/>
        </saml:

如果我在这种情况下给你一个建议，那就是：在使用IDisposable对象（如流）using时始终使用语句。除了自动刷新流之外，它还会在出现异常时释放资源：

// Add the Statements to the SAML Assertion
samlAssert.Statements.Add(samlAuthStatement);
samlAssert.Statements.Add(samlAttrStatement);

var sb = new StringBuilder();
var settings = new XmlWriterSettings 
{
    OmitXmlDeclaration = true,
    Encoding = Encoding.UTF8
};
using (var stringWriter = new StringWriter(sb))
using (var xmlWriter = XmlWriter.Create(stringWriter, settings))
using (var dictionaryWriter = XmlDictionaryWriter.CreateDictionaryWriter(xmlWriter))
{
    var samlAssertSerializer = new SamlSerializer();
    var secTokenSerializer = new WSSecurityTokenSerializer();
    samlAssert.WriteXml(
        dictionaryWriter, 
        samlAssertSerializer, 
        secTokenSerializer
    );
}

TextBox1.Text = sb.ToString();

我不确定这是否与您的案例直接相关，但这可能是与重新序列化 SAML 令牌相关的有用信息
