Question

以下代码将创建，而不是如何强制它成为<soap12:Body>标记。

XmlDocument xmlDoc = new XmlDocument();

XmlNode docNode = xmlDoc.CreateXmlDeclaration("1.0", "utf-8", null);
xmlDoc.AppendChild(docNode);

XmlNode envelopeNode = xmlDoc.CreateElement("soap12", "Envelope", "http://www.w3.org/2003/05/soap-envelope");
xmlDoc.DocumentElement?.SetAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance");
xmlDoc.DocumentElement?.SetAttribute("xmlns:xsd", "http://www.w3.org/2001/XMLSchema");

XmlNode bodyNode = xmlDoc.CreateNode(XmlNodeType.Element, "soap12", "Body", null);       
envelopeNode.AppendChild(bodyNode);

xmlDoc.AppendChild(envelopeNode);

将导致

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <Body />
</soap12:Envelope>

而不是

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
  </soap12:Body>
</soap12:Envelope>

我更喜欢使用xml linq

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;


namespace ConsoleApplication55
{
    class Program
    {

        static void Main(string[] args)
        {
            string header = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
                "<soap12:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap12=\"http://www.w3.org/2003/05/soap-envelope\">" +
                "</soap12:Envelope>";

            XDocument doc = XDocument.Parse(header);

            XElement envelope = doc.Root;
            XNamespace nsSoap12 = envelope.GetNamespaceOfPrefix("soap12");

            XElement body = new XElement(nsSoap12 + "Body");
            envelope.Add(body);

        }


    }

您需要将正确的命名空间传递给CreateNode：

XmlNode bodyNode = xmlDoc.CreateNode(XmlNodeType.Element, 
    "soap12", "Body", "http://www.w3.org/2003/05/soap-envelope");

虽然使用更现代的LINQ to XML，但整个问题更简单：

XNamespace ns = "http://www.w3.org/2003/05/soap-envelope";

var doc = new XDocument(
    new XElement(ns + "Envelope",
        new XAttribute(XNamespace.Xmlns + "xsi", "http://www.w3.org/2001/XMLSchema-instance"),
        new XAttribute(XNamespace.Xmlns + "xsd", "http://www.w3.org/2001/XMLSchema"),
        new XAttribute(XNamespace.Xmlns + "soap12", ns),
        new XElement(ns + "Body")
    )
);
