XML deserialization issue for XMLArrayItem

Question

I have to deserialize the following XML:

<section>
 <class_id>Cls101</class_id>
 <sect_no>1</sect_no>
 <class_section>class section</class_section>
 <meet_days>
   <day>M</day>
   <day>T</day>
   <day>W</day>
 </meet_days>
</section>

For which I have created the classes as below:

[Serializable]
[XmlRoot("section")]
public class Section
{
     [XmlElement("class_id")]
     public string ClassId { get; set; }

     [XmlElement("sect_no")]
     public string SectionNo { get; set; }

     [XmlElement("class_section")]
     public string ClassSection { get; set; }

     [XmlArray("meet_days")]
     [XmlArrayItem("day")]
     public List<Days> MeetDays { get; set; }
}

[Serializable]
public class Days
{
    [XmlElement("day")]
    public string Day { get; set; }
}

In the deserialized object I am getting Day as null for all 3 rows.

What am I missing here?

Because Day only has one property which is a string, consider removing the Day class and changing the Section class to read:

[XmlArray("meet_days")]
[XmlArrayItem("day")]
public List<string> MeetDays { get; set; }

That way, the M, T and W values get mapped to strings rather than a string within the Day class.

Thanks Steve. I tried that earlier and it works. But I don't need string. I need the value to be mapped to Day property.

You are not using XmlArrayItem correctly. It designates the types allowed as items in the deserialization.

Try:

[XmlArrayItem(typeof(Days))]
