我正在尝试签署一个XML文件，但不是整个文件，只是所有内部标记＆＃34; soapenv：Body＆＃34;。 他们给了我一个例子，我试图给出相同的结果，但是开始我不能得到相同的DigestValue。 我得到的那个不会改变，无论输入是什么，我想如果我改变了标签内的值，我每次都会得到一个不同的DigestValue，但我不是。 我需要知道我做错了什么。 代码如下：
doc.Load(xmlfileInput);
XmlNodeList nodo = doc.DocumentElement.GetElementsByTagName("soapenv:Body");
string nodoxml = nodo.Item(0).InnerXml;
XmlDocument doc1 = new XmlDocument();
//doc.PreserveWhitespace = true;
doc1.LoadXml(nodoxml);
//Print content to sign
System.Console.WriteLine(doc1.OuterXml);
System.Console.WriteLine("---------------------------------------------------------------------------------------------");
SignedXml signer = new SignedXml(doc1);
byte[] pkBytes = File.ReadAllBytes(privateKey); //testkey.key
RsaPrivateCrtKeyParameters pkFactory = (RsaPrivateCrtKeyParameters)PrivateKeyFactory.DecryptKey(passwordKey.ToCharArray(), pkBytes);
RSA key = DotNetUtilities.ToRSA(pkFactory);
signer.KeyInfo = new KeyInfo();
signer.KeyInfo.AddClause(new RSAKeyValue(key));
signer.SigningKey = key;
signer.SignedInfo.CanonicalizationMethod = SignedXml.XmlDsigCanonicalizationWithCommentsUrl;
Reference r = new Reference("");
XmlDsigXPathTransform XPathTransform = CreateXPathTransform(@"/dodas");
r.AddTransform(XPathTransform);
r.AddTransform(new XmlDsigEnvelopedSignatureTransform());
r.DigestMethod = "http://www.w3.org/2001/04/xmlenc#sha256";
signer.AddReference(r);
signer.ComputeSignature();
System.Console.WriteLine(signer.GetXml().OuterXml);
XmlNode nodeimported = doc.ImportNode(signer.GetXml().FirstChild.ParentNode, true);
doc.DocumentElement.GetElementsByTagName("dodas").Item(0).AppendChild(nodeimported);
string xmlFirmado = doc.OuterXml;
File.WriteAllText(xmlfileOutput, xmlFirmado);
//Éxito
System.Console.ForegroundColor = ConsoleColor.Green;
System.Console.WriteLine("Documento XML firmado con éxito!");
两个不同的跑步在控制台中显示以下内容：
第一个输出：
