我正在尝试使用带有证书的 WCF 调用 Web 服务来签署消息。

服务器仅支持以下规范化算法：' http ://www.w3.org/TR/2001/REC-xml-c14n-20010315#WithComments '

默认情况下，WCF 使用“ http://www.w3.org/2001/10/xml-exc-c14n# ”

由于无法使用配置文件对其进行配置，因此我创建了一个自定义绑定，在其中设置了自定义 SecurityAlgorithmSuite 以强制 WCF 使用服务预期的规范化算法。这是我的自定义绑定：

public class TestBinding : Binding
{
    public override BindingElementCollection CreateBindingElements()
    {
        var sec = TransportSecurityBindingElement.CreateCertificateOverTransportBindingElement();
        sec.MessageSecurityVersion = MessageSecurityVersion
            .WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10;
        sec.EnableUnsecuredResponse = true;
        sec.DefaultAlgorithmSuite = new TestSecurityAlgorithmSuite();

        return new BindingElementCollection(new BindingElement[] {
            new TextMessageEncodingBindingElement() { MessageVersion = MessageVersion.Soap11WSAddressing10 },
            sec,
            new HttpsTransportBindingElement() { RequireClientCertificate = true }
        });
    }

    public override string Scheme
    {
        get { return new HttpsTransportBindingElement().Scheme; }
    }
}

和算法套件：

public class TestSecurityAlgorithmSuite : Basic256SecurityAlgorithmSuite
{
    public override string DefaultCanonicalizationAlgorithm
    {
        get { return "http://www.w3.org/TR/2001/REC-xml-c14n-20010315#WithComments"; }
    }

    public override string ToString()
    {
        return "TestSecurityAlgorithmSuite";
    }
}

不幸的是，我得到了错误：

Canonicalization algorithm 'http://www.w3.org/TR/2001/REC-xml-c14n-20010315#WithComments' is not supported.

我开始认为所有的希望都破灭了。有什么方法可以让 WCF 使用所需的算法？

不幸的是，例外是自我描述的：当前版本的 WCF 不支持“ http://www.w3.org/TR/2001/REC-xml-c14n-20010315#WithComments ”规范化算法。
