.NET SignedXml提供了错误的摘要值

Question

我正在尝试制作一个签名的XML文档，但我要将其发送到的web服务拒绝了它，并声明签名无效。我有一些其他的代码在php中，它的工作，网络服务接受php生成和签名的xml，但不是vb.net的。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。我还尝试用an online tool验证xml签名，php的签名是正确的，而对于vb.net，它显示摘要值是错误的。这是我在vb中计算签名的函数：

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生成的xml：https://pastebin.com/jrzLsv4k

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

用于签名的xmlDoc对于这两个代码是完全相同的。两端的编码都是UTF-8。

我已经修复了这个问题，删除了整个过程中所有的空格和换行符。
