I'm using a form to display XML elements. Every time I click on a module inside a listbox I want to display its `<Code>` value for instance, in a label on the form. The problem I'm having is that the way I've done it is that the XML is being read all at once, and I'm not able to, or don't know how to, search inside my XML file. So I think I just need a way to search in XML to find the `<Code>` element.

EDIT: Here is how far I am with trying to display the `<Code>` element in the label when it matches the `<Name>` element in the listbox:

```
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{

    var document = XDocument.Load(workingDir + @"\ModulesList.xml");

    var code = from d in document.Descendants("Name")
               where d.Value == listBox1.SelectedItem.ToString()
               select d.Parent.Element("Code").Value;

    labelCodeNumber.Text = code.ToString();

}

```

But the problem is that the labelCodeNumber doesn't display the value of `code`, it displays some weird collections stuff instead. Also I'm not sure if I am doing the output right i.e. `labelCodeNumber.Text = code.ToString();`

And here is the XML:

FINAL EDIT:
I figured it out! Thanks to Marcin and psubsee for their help and contribution. This code below goes in the listbox1\_selectedindexchanged method

```
var code = from d in document.Descendants("Name")
           where d.Value == (String) listBox1.SelectedItem
           select d.Parent.Element("Code").Value;

foreach (var item in code)
{
    labelCodeNumber.Text = item.ToString();
}

```
