获取证书并放入 xml 文件时出现问题。我应该使用私钥进行签名吗？我在证书中只看到公钥。我的证书中没有私钥。

                        byte[] ckaIdd = objectAttributess[0].GetValueAsByteArray();
                        string ckaLabel = objectAttributess[1].GetValueAsString();
                        byte[] ckaValue = objectAttributess[2].GetValueAsByteArray();
                        var _rawData = ckaValue ?? throw new ArgumentNullException(nameof(ckaValue));
                        var _parsedCertificate = new X509Certificate2(_rawData);
                        ECertificate cert = new ECertificate(_parsedCertificate.GetRawCertData());

                        string signatureListString = "";
                        XmlDocument document = new XmlDocument();
                        document.Load(@"C:\Users\MyUser\Desktop\myfile.xml");
                        Esya e = new Esya();
                        Context context = e.CreateContext();
                        context.Document = document;
                        XMLSignature signature = new XMLSignature(context, false);

                        signature.addKeyInfo(new ECertificate(cert.getEncoded()));

                        //signature.sign(v);  << ! My problem is with this line

                        var inv = (XmlElement)signature.Document.GetElementsByTagName("Invoice")[0];
                        signatureListString += inv.OuterXml + "\n";

                        var elementCount = (XmlElement)document.GetElementsByTagName("ElementCount")[0];
                        if (elementCount != null)
                        {
                            elementCount.InnerText = "1";
                        }

                        var element = (XmlElement)document.GetElementsByTagName("ElementList")[0];
                        if (element != null)
                        {
                            element.InnerXml = signatureListString;
                        }

                        var xmlPageSettings = document.GetElementsByTagName("Invoice");
                        foreach (XmlElement xmlElement in xmlPageSettings)
                        {
                            xmlElement.SetAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance");
                            xmlElement.SetAttribute("xmlns:xsd", "http://www.w3.org/2001/XMLSchema");
                        }

                        session.Logout();
                        return cert;
                    }
                }

我该怎么办signature.sign(v);？如何将签名添加到 xml 文件？

您必须实现从类继承的System.Security.Cryptography.RSA类，在其实现中使用 Pkcs11Interop，然后将自定义类的实例用作SigningKey.
