Answer 1

First you have to create a SortedDictionary. this collction automatically sort according to the key.

 SortedDictionary<string, string> values = new SortedDictionary<string, string>();

And then fill data using your two lists

for (int i = 0; i < ListBoxnumbers.Items.Count; i++)
        {
            values.Add(ListBoxnumbers.Items[i].ToString(), ListBox1.Items[i].ToString());
        }

after that another loop will fill the headers

 foreach (KeyValuePair<string,string> item in values)
        {
            dt.Columns.Add(item.Value, System.Type.GetType("System.String"));
        }
