跨境通保税仓储管理系统-跨境电商订单申报加签

这是开发山东跨境电商订单申报接口时个的示列代码，供大家们参考
1、关于跨境电商订单 申报加签给出点加签示例

	/// <summary>
    ///节点签名 DigestValue
    /// </summary>
    /// <param name="sourceDoc"></param>
    /// <returns></returns>
    public static string GetDigestValue(XmlDocument sourceDoc)
    {
        RSACryptoServiceProvider signingKey = new RSACryptoServiceProvider(new CspParameters
        {
            KeyContainerName = "XML_DSIG_RSA_KEY"
        });
        SignedXml signedXml = new SignedXml(sourceDoc);
        signedXml.SigningKey = signingKey;
        new KeyInfo();
        Reference reference = new Reference();
        reference.Uri = "";
        XmlDsigEnvelopedSignatureTransform transform = new XmlDsigEnvelopedSignatureTransform();
        reference.AddTransform(transform);
        signedXml.AddReference(reference);
        signedXml.ComputeSignature();
        XmlElement xml = signedXml.GetXml();
        string result = "";
        XmlNodeList elementsByTagName = xml.GetElementsByTagName("DigestValue");
        if (elementsByTagName.Count > 0)
        {
            result = elementsByTagName[0].InnerText;
        }
        return result;
    }

        if (xmlElement.HasChildNodes)
        {
            foreach (object obj in xmlElement.ChildNodes)
            {
                XmlNode xmlNode = (XmlNode)obj;
                if (xmlNode.NodeType == XmlNodeType.Element)
                {
                    SignatureHelper.SetPrefix((XmlElement)xmlNode, prefix);
