C#线程stopped过后会自动清理资源么?

private void timer1_Tick(object sender, EventArgs e)
        {            Server.ServerAll pp = new ServerAll();
            if (op == 1)//op为静态变量，初始为0
            {
                if (wwyy.ThreadState == System.Threading.ThreadState.Suspended)
                --------一次过后变为stoppped，这时内存会自动清理资源么？？？？
                { }
            }
            dataGridView1.DataSource = pp.SelectAllWait().Tables[0];
            dataGridView2.DataSource = pp.SelectAllWait().Tables[1];
            //dataGridView计算行会多加一行
                     int p = pp.SelectAll().Tables[0].Rows.Count;
            int q = pp.SelectAll().Tables[1].Rows.Count;
            //&& (wwyy.ThreadState == System.Threading.ThreadState.Unstarted||)
            if (p != 0 )
            {
                
                wwyy = new Thread(new ThreadStart(SendData));
                wwyy.Start();
            }
            if (q != 0)
            {
                wy = new Thread(new ThreadStart(SendComment));
                wy.Start();
            }
            op = 1;
            timer1.Interval = 1000 * 60;
        }急急急急急急急急！！谢谢
