C# DigestValue对于C中的不同输入XML是相同的#

我试图对一个XML文件进行签名，但不是对整个文件进行签名，而是对标记“soapenv:Body”中的所有内容进行签名。 他们给了我一个例子，我试图得到同样的结果，但首先我不能得到同样的值。 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中的值，每次我都会得到不同的DigestValue，但我没有。 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!");

第一个输入有一个标记值

<Usuario>TEST1TEST1</Usuario>

TEST1TEST1

第二个输入有一个标记值

<Usuario>ANOTHERTEST2TEST2</Usuario>

另一个测试2测试2

但是有同样的价值

<DigestValue>47DEQpj8HBSa+/TImW+5JCeuQeRkm5NMpJWZG3hSuFU=</DigestValue>

47DEQpj8HBSa+/TImW+5JCeuQeRkm5NMpJWZG3hSuFU=

您的第一个和第二个输入是相同的……感谢您的注释！除了一个标记外，两个输入都是相同的。第一个输入是TEST1TEST1，第二个输入是：另一个test2test2
