{C#} 利用progressBar與Thread控制程式完成與執行過久強制結束

//給ProgressBar最大執行時間
progressBar1.Maximum = 10 * 1000;
string strMessage = string.Empty;
//取得、控制執行緒，目前狀態
Thread t = new Thread(database); 
t.Start();
//以ProgressBar最長時間，跑迴圈，影響ProgressBar進度
for (int i=0;i<10001;i++)
{
     progressBar1.Value = i;
     if (progressBar1.Maximum == progressBar1.Value && !t.Join(10 * 1000))
     {
          strMessage = "完成";
          break;
     }
     //執行緒是否執行超過指定時間
     if (!t.Join(10 * 1000))
     {
           strMessage = "Done";
            //強制結束執行緒
            t.Abort();
            break;
      }
}
if (progressBar1.Maximum == progressBar1.Value && !t.Join(10 * 1000))
{
    strMessage = "完成";
}
MessageBox.Show(strMessage);

//給Thread的Function
public void database()
{
    OracleConnection conn = new OracleConnection("Data Source=DB;User Id=abc;Password=abcd;");
    OracleCommand cmd = new OracleCommand();
    cmd.Connection = conn;
    cmd.CommandType = CommandType.Text;
    cmd.CommandText = @"INSERT INTO Tablename VALUES('123','1234','abc')";
    conn.Open();
    cmd.ExecuteNonQuery();
    conn.Close();
