.NET WinForm implementiert die Methode zum Hinzufügen einer Fortschrittsleiste in der Listenansicht

foreach (string d in arr)
{
    int index = lv.Items.Count + 1;
    item = new ListViewItem(new string[] { index.ToString(), d, "", "", "", "" });
    lv.Items.Add(item);
    float progress = 0;
    Rectangle SizeR = default(Rectangle);
    System.Windows.Forms.ProgressBar ProgBar = new System.Windows.Forms.ProgressBar();
    SizeR = item.SubItems[2].Bounds;
    SizeR.Width = lv.Columns[2].Width;
    ProgBar.Parent = lv;
    ProgBar.SetBounds(SizeR.X, SizeR.Y, SizeR.Width, SizeR.Height);
    ProgBar.Value = (int)progress;
    ProgBar.Visible = true;
    //取一个唯一的名字，以后好找
    ProgBar.Name = d + "progressbar";
}

//循环listview上的所有控件，按名字找到progressbar
foreach (Control item in lv.Controls)
{
    if (item.Name == d.Name + "progressbar")
    {
      ProgressBar bar = (ProgressBar)item;
      bar.Value = (int)((d.Progress) * 100);
    }
}
