String Data Extract to Array.

This should work:
private void button1_Click(object sender, EventArgs e)
{
    string[] qArray = getItemsBetween(txtResult.Text, "", "");
    string[] o1Array = getItemsBetween(txtResult.Text, "", "");
    string[] o2Array = getItemsBetween(txtResult.Text, "", "");
    string[] o3Array = getItemsBetween(txtResult.Text, "", "");
    string[] o4Array = getItemsBetween(txtResult.Text, "", "");
}

private string[] getItemsBetween(string input, string before, string after)
{
    List res = new List();

    foreach (string i in input.Split(new string[] { before }, StringSplitOptions.None))
        if (i.Contains(after))
            res.Add(i.Split(new string[] { after }, StringSplitOptions.None)[0]);

    return res.ToArray();
}
