I need to create an XML in c#. here is my expected xml result:-

XML

<?xml version="1.0" encoding="utf-8" ?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/" xmlns:arr="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
	<soapenv:Header/>
	<soapenv:Body>
		<tem:MyData>
		
			<tem:Code>10005</tem:Code>
			
			<tem:FilePath>
				<arr:string>\\url.com\filepath</arr:string>
			</tem:FilePath>
			
		</tem:MyData>
	</soapenv:Body>
</soapenv:Envelope>

I am facing issue while adding multiple attribute in soapenv:Envelope node. can any one suggest me the solution

What I have tried:

i tried following code but i did not get expected result.

C#

var doc = new XmlDocument();
XmlNode docNode = doc.CreateXmlDeclaration("1.0", "UTF-8", null);
doc.AppendChild(docNode);
 var root = doc.AppendChild(doc.CreateElement("SOAP-ENV", "Envelope", soapNs));
var body = root.AppendChild(doc.CreateElement("SOAP-ENV", "Body", soapNs));

 AddAttribute(doc.DocumentElement, "xmlns:soapenv", "http://schemas.xmlsoap.org/soap/envelope/");
 AddAttribute(doc.DocumentElement, "xmlns:tem", "http://tempuri.org/");
 AddAttribute(doc.DocumentElement, "xmlns:arr", "http://schemas.microsoft.com/2003/10/Serialization/Arrays");

  private static void AddAttribute(XmlNode node, string attribute, string value)
        {
            if (node.NodeType == XmlNodeType.Element)
            {
                node.Attributes.Append(node.OwnerDocument.CreateAttribute(attribute));
                node.Attributes[attribute].Value = value;
                foreach (XmlNode subnode in node.ChildNodes)
                {
                    AddAttribute(subnode, attribute, value);
                }
            }
        }

Managing Namespaces in an XML Document | Microsoft Learn[^]

Once you add the namespaces to a NameTable, and correct your prefixes, the XmlDocument will add the xmlns attributes for you. NB: It will only add the namespaces that are actually used - in this case, you've only used the Soap namespace, so the tempuri and schemas.microsoft.com namespaces will be omitted.

C#

var nt = new NameTable();
var nsmgr = new XmlNamespaceManager(nt);
nsmgr.AddNamespace("soapenv", soapNs);
nsmgr.AddNamespace("tem", "http://tempuri.org/");
nsmgr.AddNamespace("arr", "http://schemas.microsoft.com/2003/10/Serialization/Arrays");

var doc = new XmlDocument(nt);
doc.AppendChild(doc.CreateXmlDeclaration("1.0", "UTF-8", null));
var root = doc.AppendChild(doc.CreateElement("soapenv", "Envelope", SoapNamespace));
var body = root.AppendChild(doc.CreateElement("soapenv", "Body", SoapNamespace));

If you can switch to XLinq[^], managing namespaces becomes much easier:

C#

XNamespace SoapNs = "http://schemas.xmlsoap.org/soap/envelope/";
XNamespace TempNs = "http://tempuri.org/";
XNamespace ArrayNs = "http://schemas.microsoft.com/2003/10/Serialization/Arrays";

var doc = new XDocument(
    new XDeclaration("1.0", "utf-8", null),
    new XElement(SoapNs + "Envelope",
        new XAttribute(XNamespace.Xmlns + "soapenv", SoapNs),
        new XAttribute(XNamespace.Xmlns + "tem", TempNs),
        new XAttribute(XNamespace.Xmlns + "arr", ArrayNs),
        new XElement(SoapNs + "Body")
    )
);
