XmlSerializer problem with prefix and namespace

Question

Hello, Is there a way to generate this output via serialization?


	
		
			#_DATA_#

I need to send this request via a REST interface. The customer gave me this specification.

biz and doc are arbitrary, any value can be used Is this specified in the XML?

Prefix can be q1, doc and so on. The other person does not evaluate this. There are no exchange conflicts here. What do you use it for then? What is it good for?

Current state.

public class ZCOATINGORDER
{
	[XmlElement(ElementName = "IM_BACK")]
	public string IMBACK { get; set; }
}

[XmlRoot(ElementName = "body")]
public class Body 
{
	[XmlElement(ElementName = "Z_COATING_ORDER", Namespace = "urn:sap-com:document:sap:rfc:functions")]
	public ZCOATINGORDER ZCOATINGORDER { get; set; }
}

[XmlRoot("COM_1", Namespace = "urn:biztalk-org:biztalk:biztalk_1")]
public class COM1
{
	[XmlElement(ElementName = "body")]
	public Body Body { get; set; }

	[XmlAttribute(AttributeName = "xmlns")]
	public string Xmlns { get; set; }        

	private XmlSerializerNamespaces _Namespaces;
	public XmlSerializerNamespaces NameSpaces
	{
		get
		{
			if (_Namespaces == null)
			{
				_Namespaces = new XmlSerializerNamespaces();
				_Namespaces.Add("ns0", "urn:biztalk-org:biztalk:biztalk_1");
				_Namespaces.Add("ns1", "urn:sap-com:document:sap:rfc:functions");
			}
			return _Namespaces;
		}

Hi @Noah Aas , Welcome to Microsoft Q&A,

It is possible to make some tweaks to the C# class and use 'XmlSerializer' for serialization.


using System;
using System.Xml.Serialization;
using System.IO;

public class ZCOATINGORDER
{
    [XmlElement(ElementName = "IM_BACK")]
    public string IMBACK { get; set; }
}

[XmlRoot(ElementName = "body")]
public class Body 
{
    [XmlElement(ElementName = "Z_COATING_ORDER", Namespace = "urn:sap-com:document:sap:rfc:functions")]
    public ZCOATINGORDER ZCOATINGORDER { get; set; }
}

[XmlRoot("COM_1", Namespace = "urn:biztalk-org:biztalk:biztalk_1")]
public class COM1
{
    [XmlElement(ElementName = "body")]
    public Body Body { get; set; }

    private XmlSerializerNamespaces _Namespaces;
    public XmlSerializerNamespaces NameSpaces
    {
        get
        {
            if (_Namespaces == null)
            {
                _Namespaces = new XmlSerializerNamespaces();
                _Namespaces.Add("q1", "urn:biztalk-org:biztalk:biztalk_1");
                _Namespaces.Add("doc", "urn:sap-com:document:sap:rfc:functions");
            }
            return _Namespaces;
        }
    }
}

Serialize to XML

public class Program
{
    public static void Main(string[] args)
    {
        COM1 com1 = new COM1
        {
            Body = new Body
            {
                ZCOATINGORDER = new ZCOATINGORDER
                {
                    IMBACK = "Rü-TEST"
                }
            }
        };

        XmlSerializer serializer = new XmlSerializer(typeof(COM1));

        XmlWriterSettings settings = new XmlWriterSettings
        {
            Indent = true,
            OmitXmlDeclaration = true
        };

        using (StringWriter textWriter = new StringWriter())
        {
            using (XmlWriter xmlWriter = XmlWriter.Create(textWriter, settings))
            {
                serializer.Serialize(xmlWriter, com1, com1.NameSpaces);
            }

            string xmlOutput = textWriter.ToString();
            Console.WriteLine(xmlOutput);
        }
    }
}

Output:

Adjusted C# Code

Define Classes with Proper Namespace Prefixes:
- Use XmlType and XmlElement attributes to specify namespaces.
- Use XmlSerializerNamespaces to add namespace prefixes.


using System;

using System.IO;

using System.Xml.Serialization;

public class ZCOATINGORDER

{

    [XmlElement(ElementName = "IM_BACK")]

    public string IMBACK { get; set; }

}

public class Body

{

    [XmlElement(ElementName = "Z_COATING_ORDER", Namespace = "urn:sap-com:document:sap:rfc:functions")]

    public ZCOATINGORDER ZCOATINGORDER { get; set; }

}

[XmlRoot(ElementName = "COM_1", Namespace = "urn:biztalk-org:biztalk:biztalk_1")]

public class COM1

{

    [XmlElement(ElementName = "body")]

    public Body Body { get; set; }

    [XmlNamespaceDeclarations]

    public XmlSerializerNamespaces Namespaces { get; set; }

    public COM1()

    {

        Namespaces = new XmlSerializerNamespaces();

        Namespaces.Add("q1", "urn:biztalk-org:biztalk:biztalk_1");

        Namespaces.Add("doc", "urn:sap-com:document:sap:rfc:functions");

    }

}

Serialize to XML:
- Serialize the COM1 object to XML using XmlSerializer.


public class Program

{

    public static void Main()

    {

        // Create the object with the data to serialize

        var com1 = new COM1

        {

            Body = new Body

            {

                ZCOATINGORDER = new ZCOATINGORDER

                {

                    IMBACK = "#_DATA_#"

                }

            }

        };

        // Serialize the object to XML

        var serializer = new XmlSerializer(typeof(COM1));

        using (var stringWriter = new StringWriter())

        {

            serializer.Serialize(stringWriter, com1);

            var xmlString = stringWriter.ToString();

            Console.WriteLine(xmlString);

        }

    }

}

Output:

The above code will produce the following XML:






  

    

      #_DATA_#

This XML matches the desired output format, including the namespace prefixes for COM_1 and Z_COATING_ORDER.
