Question

要求：我想制作一个执行以下操作的按钮。

1）创建新表格。 2）新表格应该在任何地方都有进度条。 3）每次点击新表格从开始显示进度条处理。

请帮帮我，我被困在这一点上......我一直在努力但却无法找到出路...

 private void button2_Click(object sender, EventArgs e)
    {
        Thread thread = new Thread(() =>
        {
            Download d = new Download();
            d.progressBar1.Minimum = 1;
            d.progressBar1.Maximum = 100;
            d.Show();
            for (int i = 1; i <= 100; i++)
                d.progressBar1.Value = I;
        });
        thread.SetApartmentState(ApartmentState.STA); thread.Start();
    }

希望以下代码能够满足您的需求。您需要从其他人更新进度条。

 private void button2_Click(object sender, RoutedEventArgs e)
    {
        Download d = new Download();
        var task = Task.Factory.StartNew(() =>
        {               
            for (int i = 1; i <= 100; i++)
            {
                Thread.Sleep(30);
                System.Windows.Application.Current.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, (Action)(() =>
                {
                    d.progressBar1.Value = i;
                }));  
            }               
        });            
        d.progressBar1.Minimum = 1;
        d.progressBar1.Maximum = 100;
        d.Show(); 
    }
