Winform: How to Collect All String Values from a ListBox

I'd like to be able to collect all the string values in a Winform ListBox. At the moment my code loops through the ListBox and gets the values, but it's appending all values together in one long string:

private string GetFormNumberValues()
{
    string formNumbers = "";
    foreach (string item in this.lbFormNumbers.Items)
    {
        formNumbers += item.ToString();
    }
    return formNumbers;
}

How can I collect each individual string value to use for later? Thanks.

You can have them in a List this way:

var list = listBox1.Items.Cast<object>().Select(x => x.ToString()).ToList();

Try something like this:

private string[] GetFormNumberValues()
{
    List<string> strings = new List<string>();
    foreach (string item in this.lbFormNumbers.Items)
    {
        strings.Add(item.ToString());
    }
    return strings.ToArray();
}

(Depending on your needs, you could simplify this by returning a List rather than an array...)
