进度条与listview解决方案

进度条与listview
如何实现 1、进度条每满一次 text_time_slice.Text数字-1（初始值为3）
2、进度条每满一次 listview中的就删除第一行数据。
下面为代码
pba为进度条
list_readY为listview 为5行。

C# code

 private void timerpba_Tick(object sender, EventArgs e)        {                        int n = list_ready.Items.Count;//返回行数            //text_time_slice.Text = n.ToString();            pba.Maximum = 3;            pba.Value = 0;//设置当前值            pba.Step = 1;//设置没次增长多少            for (int m = 0; m < n; m++)//进度满值的循环的次数            {                for (int j = 0; j < 3; j++)//循环                {                    //text_time_slice.Text = j.ToString();//[color=#FF9900]如何实现进度条加1 text_time_slice.Text中的数就-1？[/color]                    System.Threading.Thread.Sleep(500);//暂停1秒                    pba.Value += pba.Step;//让进度条增加一次                    //for();                    // timerpba.Enabled = true;                }                if (this.pba.Value == 3)                {                    //text_time_slice.Text = i.ToString();                    System.Threading.Thread.Sleep(500);//进度条满后停顿0.5秒后继续循环                    list_ready.Items.Remove(1);//[color=#FF0000]如何在此时删除listview的第一行？？？？？？[/color]                    pba.Value = 3;                    pba.Value = 0;                                        //pba.PerformStep();                }            }timerpba.Enabled = false;        }

C# code

private void timerpba_Tick(object sender, EventArgs e)        {                        int n = list_ready.Items.Count;//返回行数            text_time_slice.Text = n.ToString();            pba.Maximum = 3;            pba.Value = 0;//设置当前值            pba.Step = 1;//设置没次增长多少            for (int m = 0; m < n; m++)//进度满值的循环的次数            {                for (int j = 0; j < 3; j++)//循环                {                    text_time_slice.Text = Convert.ToInt32(t_time_slice.Text)-1;                  System.Threading.Thread.Sleep(500);//暂停1秒                    pba.Value += pba.Step;//让进度条增加一次                    //for();                    // timerpba.Enabled = true;                }                if (this.pba.Value == 3)                {                    //text_time_slice.Text = i.ToString();                    System.Threading.Thread.Sleep(500);//进度条满后停顿0.5秒后继续循环                    if(list_ready.Items.Count>0)                  {                    list_ready.Items.Remove(0);                  }                    pba.Value = 3;                    pba.Value = 0;                                        //pba.PerformStep();                }            }timerpba.Enabled = false}
