Adding XML elements to ListBox

Question

I don't know how to convert the type for name so that each element in it can be added to my ListBox. If someone could help that would be much appreciated.

XDocument doc = XDocument.Load(workingDir + @"\Moduleslist.xml");

var names = doc.Root.Descendants("Module").Elements("Name").Select(b => b.Value);

listBox1.Items.AddRange(names);

I'm getting an error on AddRange(names) saying invalid arguments

variable names is array or not...!

Is it a forms app, web forms, or what?

names is IEnumerable<String> and listBox.Items.AddRange is expecting an object array and there is no implicit cast between them.

A quick solution would be to:

listBox1.Items.AddRange(names.ToArray());

or

foreach (var item in names)
{
    listBox1.Items.Add(item);
}

Thanks dude that works nicely, I've substituted that for my XmlTextReader code which populated the listbox instead. Thank you

Try this code instead of your last line of code:

listBox1.DataSource = names;
this.listBox1.DisplayMember = YOURDISPLAYMEMBER;
this.listBox1.ValueMember = YOURVALUEMEMBER;

maybe:

listBox1.Items.AddRange(doc.Root.Descendants("Module").Elements("Name").Select(b => b.Value).ToArray());
