xml creation in C#

Question

I want final xml as follows...

<Programs>
  <Program><id>4</id><isRead>true</isRead><isWrite>false</isWrite></Program>
  <Program><id>8</id><isRead>true</isRead><isWrite>true</isWrite></Program>
</programs>

now following is the code written

XmlDocument xmlDoc = new XmlDocument();
XmlNode rootNode = xmlDoc.CreateNode(XmlNodeType.Element,"programs",null);
xmlDoc.AppendChild(rootNode);


foreach (dynamic item in access)
{
  XmlNode myXmlNode = JsonConvert.DeserializeXmlNode(item.ToString(), "program");
  rootNode.AppendChild(myXmlNode); //error
}

where in myXmlNode.InnerXml, I am already getting following

<Program><id>4</id><isRead>true</isRead><isWrite>false</isWrite></Program>

And so, running the loop for all children to add in which is parent. But I am getting error for line //error as marked above. Error is:

The specified node cannot be inserted as the valid child of this node, because the specified node is the wrong type.

Answer 1

You are trying to insert different type of xml node. You could use ImportNode to apply it.

foreach (dynamic item in access)
{
    XmlNode myXmlNode = JsonConvert.DeserializeXmlNode(item.ToString(), "program");
    rootNode.AppendChild(rootNode.OwnerDocument.ImportNode(myXmlNode.FirstChild,true));
}

I would recommend you create a model for what you are looking to create in XML, then serialize a list of the model to XML.

The reason being that you will end up with something far more maintainable.

Your model would be something like this:

public class Program
{
    public int Id { get; set; }
    public bool IsRead { get; set; }
    public bool IsWrite { get; set; }
}

And you can serialize it by following this article:
