winform進度條

首先在屬性欄裏面把progressBar1的value設爲0，timer的時間Interval屬性設爲1000，也就是1秒，那麼每次就讓progressBar1的value加20

private void timer1_Tick(object sender, EventArgs e)           //在timer的tick事件裏面
        {
            if (progressBar1.Value < 100)              //如果進度少於100，就讓它自加1
            {
                progressBar1.Value =  progressBar1.Value + 20;                
            }
            else                      //但等於100的時候，顯示主窗體
            {

                QQMain qm = new QQMain();
                qm.Show();
                this.Close();
                timer1.Stop();
            }
        }
