如何在.NET核心中使用x509证书对xml文件签名？

using System.Security.Cryptography;
using System.Security.Cryptography.X509Certificates;
using System.Security.Cryptography.Xml;
using System.Xml;

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("path/to/xml/file.xml");

SignedXml signedXml = new SignedXml(xmlDoc);

X509Certificate2 certificate = GetCertificate();

Reference reference = new Reference();
reference.Uri = "";

signedXml.AddReference(reference);

KeyInfo keyInfo = new KeyInfo();
keyInfo.AddClause(new KeyInfoX509Data(certificate));

signedXml.KeyInfo = keyInfo;

signedXml.ComputeSignature();

XmlElement xmlDigitalSignature = signedXml.GetXml();
xmlDoc.DocumentElement.AppendChild(xmlDoc.ImportNode(xmlDigitalSignature, true));

xmlDoc.Save("path/to/signed/xml/file.xml");
