如题。。。代码如下：
public static ArrayList getData()
        {

            MySqlConnection con = new MySqlConnection("Host=localhost;Port=3306;UserName=guru2b;Password=g00r002b;Persist Security Info=True;Database=coalthreed");
            con.Open();
            string str = "select *from TestData";
            MySqlDataAdapter da = new MySqlDataAdapter(str, con);
            DataSet ds = new DataSet();        da.Fill(ds);        
            count = ds.Tables[0].Rows.Count;
            ArrayList List1 = new ArrayList();
            Random ran = new Random();
            for (int i = 0; i < count; i++)
            {
                List1.Add(Convert.ToInt32(ds.Tables[0].Rows[i][1]));
            }
            return List1;
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            for (int i = 0; i < 5; i++)
            {
                arry.RemoveAt(i);
            }
            this.Refresh();

            drawcurve.StartDraw(this.groupBox1.CreateGraphics(), arry);
        }

        private void Move_Left_Click(object sender, EventArgs e)
        {
            timer1.Enabled = true;

为什么没人理啊。。。我知道我是菜鸟，问题可能过于的简单的。。。不过好心人们帮帮吧。。会有好运的。。

可是可是。。。我的另一个代码程序用的时候还好好地连接上了啊。。。难不成不能一起用？？
