Question

I’ve got this XML;

<ChartXml>
   <Category type="xAxis">
      <Value>Mon</Value>
      <Value>Tue</Value>
      <Value>Wed</Value>
      <Value>Thurs</Value>
      <Value>Friday</Value>
   </Category>
</ChartXml>

And this class structure;

[XmlRoot("ChartXml")]
public class ChartXml
{
    [XmlElement("Category")]
    public Category Category;            
}

public class Category
{        
    [XmlAttribute("type")]
    public string Type;        
    [XmlArray("Value")]
    public List<string> Values;
}

Now when I try to serialise the XML to a ChartXml object, I get object containing the Category with the type attribute set correctly, but i dont get my list of strings.

I’m guessing its something wrong with the way i’ve set up my classes.

Thanks,
james.

Use [XmlElement("Value")] instead of [XmlArray("Value")], e.g.:

[XmlRoot("ChartXml")]
public class ChartXml
{
    [XmlElement("Category")]
    public Category Category;
}

public class Category
{
    [XmlAttribute("type")]
    public string Type;

    [XmlElement("Value")]
    public List<string> Values;
}

Serialization:

var obj = new ChartXml { Category = new Category { Type = "t", Values = new List<string> { "a", "b", "c" } } };
var ser = new XmlSerializer(obj.GetType());

using (var tw=new StringWriter())
{
    ser.Serialize(tw, obj);

    Console.WriteLine(tw.ToString());
}

Output:

<?xml version="1.0" encoding="utf-16"?>
<ChartXml xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http:
//www.w3.org/2001/XMLSchema">
  <Category type="t">
    <Value>a</Value>
    <Value>b</Value>
    <Value>c</Value>
  </Category>
</ChartXml>
