求简单进度条代码和计时器代码

        private void timer1_Tick(object sender, EventArgs e)

        {

            label1.Text = (Convert.ToInt32(label1.Text) + 1).ToString();//每秒动label1的值加1

        }



//按钮1开始

        private void button1_Click(object sender, EventArgs e)

        {

            progressBar1.Style = ProgressBarStyle.Marquee;

            timer1.Start();



            MethodInvoker mi = new MethodInvoker(DoSomething1);

            mi.BeginInvoke(null, null);

        }



//按钮2停止

private void button2_Click(object sender, EventArgs e)

        {

            var="aaa";

        }





        //完成

        private void Finish()

        {

            progressBar1.Style = ProgressBarStyle.Blocks;

            timer1.Stop();

        }



        //循环方法

        private void DoSomething1()

        {

            //执行循环方法

            while (var != "aaa")

            {

                //暂停10秒

                System.Threading.Thread.Sleep(10000);

            }



            BeginInvoke(new MethodInvoker(Finish));

        }
