  您可以在更新ListBox之前取消订阅selectedIndexChanged，然后立即重新订阅它 . 这是一种常见的做法 .

  既然你没有给出任何代码示例，我在这里做一些猜测 .

  // Enumerable of all the synchronized list boxes
  IEnumerable<ListBox> mListBoxes = ...
  ...
  public void OnSelectedIndexChanged(object sender, EventArgs e) {
      var currentListBox = (ListBox)sender;
  
      // Do this for every listbox that isn't the one that was just updated
      foreach(var listBox in mListBoxes.Where(lb => lb != currentListBox)) {
          listBox.SelectedIndexChanged -= OnSelectedIndexChanged;
          listBox.SelectedIndex = currentListBox.SelectedIndex;
          listBox.SelectedIndexChanged += OnSelectedIndexChanged;
      }
  }
