How to deserialize this nested xml in c# objects

Question

I am using silverlight ot achieve deserialisation of xml which looks like this:

String xmlString=

<attributes>
    <value>1</value>
    <showstatus>yes</showstatus>
    <disableothers>
        <disableother>
            <disablevalue>1</disablevalue>
            <todisable>skew</todisable>
            <todisable>skew_side</todisable>
        </disableother>
        <disableother>
            <disablevalue>0</disablevalue>
            <todisable>automodel</todisable>
        </disableother>
    </disableothers>
</attributes>

In my attempt to achieve this i feel like i have something in the classes. The classes are as below:

 [XmlRoot(ElementName = "attributes")]
    public class Attributes
    {
      [XmlElement("disableOthers")]
        public List<DisableOthers> DisableOthers { get; set; }
    }



[XmlRoot(ElementName = "disableOthers")]
    public class DisableOthers
    {
        [XmlElement("disableOthers")]
        public List<DisableOther> DisableOther { get; set; }
    }


 [XmlRoot(ElementName = "disableOther")]
    public class DisableOther
    {
        [XmlElement("disablingitem")]
        public int DisablingItem { get; set; }

        [XmlElement("todisable")]
        public int ToDisable { get; set; }

        [XmlElement("disablevalue")]
        public int DisableValue { get; set; }
    }

Could some one please correct me if my classes are correct corresponding to the given xml ? Would be a big help.

NOTE: The problem exact is when i created object of the parent class then it gives "0" value. And i have already tried it then i came here on stackoverflow.

You miss value and status in attributes and why don't you try it? — rene

What does it gives "0" value mean? And no need to bold stuff... — rene

You don't need DisableOthers class. Just use property with XmlArrayItem attribute:

[XmlArrayItem("disableother", IsNullable=false)]
[XmlArray("disableOthers")]
public DisableOther[] DisableOthers { get; set; }

Complete mapping looks like:

[XmlRoot("attributes")]    
public class Attributes
{
    [XmlElement("value")]
    public byte Value { get; set; }

    [XmlElement("showstatus")]
    public string ShowStatus { get; set; }        

    [XmlArray("disableothers")]
    [XmlArrayItem("disableother", IsNullable = false)]
    public DisableOther[] DisableOthers { get; set; }
}

[XmlRoot("disableOther")]
public class DisableOther
{
    [XmlElement("disablevalue")]
    public byte DisableValue { get; set; }

    [XmlElement("todisable")]
    public string[] ToDisable { get; set; }
}

Deserialization:

XmlSerializer serializer = new XmlSerializer(typeof(Attributes));
using (var reader = new StringReader(xmlString))
{
    var attributes = (Attributes)serializer.Deserialize(reader);
    attributes.Dump();
}

Output:

{
  Value: 1,
  ShowStatus: "yes",
  DisableOthers: [
    {
      DisableValue: 1,
      ToDisable: [ "skew", "skew_side" ]
    },
    {
      DisableValue: 0,
      ToDisable: [ "automodel" ]
    }
  ]
}

Ok let me implement first. will come soon to mark you as answer. Thanks

@user234839 yep, sorry. Also you need to use XmlArray attribute instead of XmlElement. Now it works fine - just checked. I'll add full mapping

Big thanks. I have adoubt . Why it gives esception when i put "[XmlRoot(ElementName = "disableOther")]" instead of " [XmlRoot("disableOther")]" before public class DisableOther{...} ?

@user234839 there is no difference between these two definitions. Latter one also assigns "disableOther" to ElementName property. Maybe there is some other issue causes exception
