我想要的是更新ListViewItem的文本，而不会看到任何闪烁。
这是我的更新代码（多次调用）：
listView.BeginUpdate(); listViewItem.SubItems[0].Text = state.ToString(); // update the state listViewItem.SubItems[1].Text = progress.ToString(); // update the progress listView.EndUpdate();
我看过一些解决方案，其中涉及覆盖组件的 WndProc():
WndProc():
protected override void WndProc(ref Message m) { if (m.Msg == (int)WM.WM_ERASEBKGND) { m.Msg = (int)IntPtr.Zero; } base.WndProc(ref m); }
他们说这解决了问题，但就我而言，没有 。我相信这是因为我在每个项目上都使用了图标。
要结束这个问题，这里是一个帮助程序类，当为表单中的每个ListView或任何其他ListView的派生控件加载表单时，应调用该类。感谢“ Brian Gillespie”提供的解决方案。
