无法将结果写入文本文件-C#中

我有以下代码从每个html页面中提取2个对象并将其保存在数组中。最后将其写入文本文件。但我在文本文件中看不到结果。

提前感谢

for (int y = 0; y < 9; y++)
{
    if (IDs[y] == null)
    break;
    else
    {
        string item = Convert.ToString(IDs[y]);
        string url = "http://mu/tr/";
        string URL = url+item;
        WebClient web = new WebClient();
        String html= web.DownloadString(URL);
        MatchCollection m1 = Regex.Matches(html, @"<strong>'s*(.+?)'s*</strong>");
        MatchCollection m2 = Regex.Matches(html, @"<title>'s*(.+?)'s*</title>");
        foreach(Match m in m1)
        {
           string Gre = m.Groups[1].Value;
           string sic = m.Groups[2].Value;
           ITEM [y][0] = Convert.ToString(item);
           ITEM [y][1] = sic;
           ITEM [y][2] = Gre;
        }
     }
 }
 for (int row = 0; row < 9; row++)
 {
    for (int col = 0; col < 3; col++)
    {
        SIC.Write(ITEM[row][col] + " ");
    }
 SIC.WriteLine();
 }
SIC.WriteLine();
