Deserializing XML

Question

I am trying to access the node <accessmode> in the xml for a specific <action>.

<controller name="Job">
  <roles>
    <role>1</role>
    <role>3</role>
    <role>4</role>
  </roles>
  <actions>
    <action name="Index">
      <roles>
        <role>1</role>
        <role>4</role>
      </roles>
      <accessmode>1</accessmode>
    </action>
    <action name="Warning">
      <roles>
        <role>1</role>
        <role>3</role>
      </roles>
      <accessmode>3</accessmode>
    </action>
  </actions>
</controller>

I tried with the below code.

    private string mode;
    [XmlArrayItem(ElementName = "action")]
    [XmlElement(ElementName = "accessmode")]
    public string Mode
    {
        get { return mode; }
        set { mode = value; }
    }

Since the <accessmode> is an element under the arrayitem of I tried so. But, I am getting the value as null. Any help will be appreciated.

Your usage of the XmlArrayItem attribute is incorrect. It is used on collection properties to specify how the items of the collection are serialized. You should remove this attribute from the Mode property, and put this property in a Action class that maps to the <action> element.
