如何用C#中的可重用类改进windows窗体工具

我是编程界的新手，无法从Robert Jeppesen的"如何避免数千个不必要的ListView.SelectedIndexChanged事件"中理解如何使用此代码。

public class DoublebufferedListView : System.Windows.Forms.ListView
{
 private Timer m_changeDelayTimer = null;
 public DoublebufferedListView()
    : base()
 {
    // Set common properties for our listviews
    if (!SystemInformation.TerminalServerSession)
    {
       DoubleBuffered = true;
       SetStyle(ControlStyles.ResizeRedraw, true);
    }
 }
 /// <summary>
 /// Make sure to properly dispose of the timer
 /// </summary>
 /// <param name="disposing"></param>
 protected override void Dispose(bool disposing)
 {
    if (disposing && m_changeDelayTimer != null)
    {
       m_changeDelayTimer.Tick -= ChangeDelayTimerTick;
       m_changeDelayTimer.Dispose();
    }
    base.Dispose(disposing);
 }
 /// <summary>
 /// Hack to avoid lots of unnecessary change events by marshaling with a timer:
 /// https://stackoverflow.com/questions/86793/how-to-avoid-thousands-of-needless-listview-selectedindexchanged-events
 /// </summary>
 /// <param name="e"></param>
 protected override void OnSelectedIndexChanged(EventArgs e)
 {
    if (m_changeDelayTimer == null)
    {
       m_changeDelayTimer = new Timer();
       m_changeDelayTimer.Tick += ChangeDelayTimerTick;
       m_changeDelayTimer.Interval = 40;
    }
    // When a new SelectedIndexChanged event arrives, disable, then enable the
    // timer, effectively resetting it, so that after the last one in a batch
    // arrives, there is at least 40 ms before we react, plenty of time 
    // to wait any other selection events in the same batch.
    m_changeDelayTimer.Enabled = false;
    m_changeDelayTimer.Enabled = true;
 }
 private void ChangeDelayTimerTick(object sender, EventArgs e)
 {
    m_changeDelayTimer.Enabled = false;
    base.OnSelectedIndexChanged(new EventArgs());
 }
}

因此，它是一个可重用的类，我想将它的行为添加到我已经存在的ListViews中。我目前正在同一个url上使用Ian Boyd提供的代码进行管理，并将此代码添加到我的所有ListView中。问题是，我目前正在开发的ERP程序中已经有太多ListView了，而且新的ListView总是不断出现。总是重写相同的代码似乎是一种浪费。

Timer changeDelayTimer = null;
private void lvResults_SelectedIndexChanged(object sender, EventArgs e)
{
    if (this.changeDelayTimer == null)
    {
        this.changeDelayTimer = new Timer();
        this.changeDelayTimer.Tick += ChangeDelayTimerTick;
        this.changeDelayTimer.Interval = 200; //200ms is what Explorer uses
    }
    this.changeDelayTimer.Enabled = false;
    this.changeDelayTimer.Enabled = true;
}
private void ChangeDelayTimerTick(object sender, EventArgs e)
{
    this.changeDelayTimer.Enabled = false;
    this.changeDelayTimer.Dispose();
    this.changeDelayTimer = null;
    //Add original SelectedIndexChanged event handler code here
    //todo
}

我试着从谷歌上搜索这个话题的答案，但我用的关键词找不到合适的文章。希望这里有人能指导我如何将这些被视为"组件"的"类"与windows窗体工具一起使用。

var lb = new DoublebufferedListView();
yourForm.Controls.Add(lb);
