从C#代码使用SAML2.0的CustomBinding

我有一个由政府机构提供的wsdl，我用它来使用服务。 我使用以下程序： 我创建了一个CustomBinding，其中包含用于身份验证的必要证书。代码如下：

 var sec = new AsymmetricSecurityBindingElement(
           new X509SecurityTokenParameters(X509KeyIdentifierClauseType.Any, SecurityTokenInclusionMode.Never),
           new X509SecurityTokenParameters(X509KeyIdentifierClauseType.Any, SecurityTokenInclusionMode.AlwaysToRecipient));
sec.MessageSecurityVersion = MessageSecurityVersion.WSSecurity10WSTrust13WSSecureConversation13WSSecurityPolicy12BasicSecurityProfile10;
sec.SecurityHeaderLayout = SecurityHeaderLayout.Strict;
sec.IncludeTimestamp = true;
sec.SetKeyDerivation(false);
sec.KeyEntropyMode = System.ServiceModel.Security.SecurityKeyEntropyMode.ServerEntropy;
sec.EnableUnsecuredResponse = true;              
CustomBinding myBinding = new CustomBinding();
myBinding.Elements.Add(sec);
myBinding.Elements.Add(new TextMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8));
myBinding.Elements.Add(new HttpsTransportBindingElement());

这段代码创建了一个带有标题的Soap，但只正确插入了安全标签。在这个标记之前，我必须插入一个Action标记，然后插入一个断言。Action标记我不知道如何插入它，我创建了一个SAML 2.0断言，如下所示：

Saml2Assertion oAssertion = new Saml2Assertion(new Saml2NameIdentifier("MY"));
oAssertion.Subject = new Saml2Subject(new Saml2NameIdentifier("ident"));
Saml2Conditions asCondition = new Saml2Conditions();
asCondition.NotBefore = DateTime.Now;
asCondition.NotOnOrAfter = DateTime.Now.AddMinutes(15);
oAssertion.Conditions = asCondition;
Saml2AuthenticationStatement asAuthnStatement = new Saml2AuthenticationStatement(new Saml2AuthenticationContext());
oAssertion.Statements.Add(asAuthnStatement);

如果可能的话，我希望仅使用C#代码获得一个Soap，其组成如下： 带有标记ACTION、ASSERTION和Security（我已经有了）的头，如下面的示例（Body标记由Wsdl正确生成）：

有可能得到我想要的吗？我的推理错了吗？感谢所有想帮助我的人。
