You can use LINQ.

//string command = "SELECT category_id, name FROM CATEGORY ORDER BY name";
//List list = database.Select(command, false);
// sample data...
List list = new List { new string[] { "aaa", "bbb" }, new string[] { "ccc", "ffffd" } };

cbxCategory.Items.Clear();

foreach (string[] result in list)
{
    cbxCategory.Items.Add(new ComboBoxItem(result[1], result[0]));
}

ComboBoxItem tmp = cbxCategory.Items.OfType().Where(x => x.ResultFirst == "bbb").FirstOrDefault();
if (tmp != null)
    cbxCategory.SelectedIndex = cbxCategory.Items.IndexOf(tmp);

ComboBoxItem class:

class ComboBoxItem
{
    public string ResultFirst { get; set; }
    public string ResultSecond { get; set; }

    public ComboBoxItem(string first, string second)
    {
        ResultFirst = first;
        ResultSecond = second;
    }
}
