.NET SignedXml 提供错误的摘要值

Question

我正在尝试创建一个已签名的 XML 文档，但我发送它的 Web 服务拒绝了它并声明签名无效。我在 php 中有一些其他代码并且它可以工作，Web 服务接受 php 生成并签名 xml 但不接受 vb.net 。我已经使 php 和 vb.net 输入 xml 完全相等，但它们仍然生成不同的摘要值。我还尝试使用 an online tool 来验证 xml 签名并且 php 那里是正确的，对于 vb.net 它说摘要值是错误的。这是我在 vb 中用于计算签名的函数：

Private Function PotpisiXml(cert As X509Certificate2, ByVal rsa As RSACryptoServiceProvider, ByVal xmlStream As MemoryStream) As XmlDocument
    xmlStream.Position = 0
    Dim xmlDoc As New XmlDocument()
    xmlDoc.Load(xmlStream)
    Dim signedXml As New SignedXml(xmlDoc)
    signedXml.SigningKey = rsa

    Dim reference As New Reference()
    reference.Uri = "#racunId"
    Dim env As New XmlDsigEnvelopedSignatureTransform()
    Dim ec14n As New XmlDsigExcC14NTransform()
    reference.AddTransform(env)
    reference.AddTransform(ec14n)
    signedXml.AddReference(reference)

    Dim keyInfo As New KeyInfo()
    Dim kdata As New KeyInfoX509Data(cert)
    Dim xserial As X509IssuerSerial
    xserial.IssuerName = cert.IssuerName.Name
    xserial.SerialNumber = cert.SerialNumber
    kdata.AddIssuerSerial(xserial.IssuerName, xserial.SerialNumber)
    keyInfo.AddClause(kdata)

    signedXml.ComputeSignature()
    signedXml.KeyInfo = keyInfo
    Dim xmlDigitalSignature As XmlElement = signedXml.GetXml()

    xmlDoc.DocumentElement.AppendChild(xmlDoc.ImportNode(xmlDigitalSignature, True))
    Return xmlDoc
End Function

vb.net生成xml：https://pastebin.com/jrzLsv4k

php生成xml：https://pastebin.com/kbsE2PH7

xml用于签名的文档对于两种代码来说完全相同。双方的编码都是 UTF-8。

我已经通过删除过程中各处的所有空格和换行符解决了这个问题。
