推荐答案

在 ContextMenuStrip 的 Opening 事件中使用 answer 查询当前鼠标光标位置可能会在打开条带稍微延迟时传递错误的位置.

Using the answer to query the current mouse cursor position in the Opening event of the ContextMenuStrip can deliver the wrong position when opening the strip is delayed a bit.

如果需要真正点击的位置，从控件的属性中去掉ContextMenuStrip，在控件的MouseDown事件中手动打开上下文菜单.您可以在此处访问实际点击位置.

If you need the really clicked position, remove the ContextMenuStrip from the property of the control and manually open the context menu in the MouseDown event of the control. There you have access to the actual click position.

private void panel1_MouseDown(object sender, MouseEventArgs e)
{
    if(e.Button == MouseButtons.Right)
    {
        var relativeClickedPosition = e.Location;
        var screenClickedPosition = (sender as Control).PointToScreen(relativeClickedPosition);
        contextMenuStrip1.Show(screenClickedPosition);
    }
}

relativeClickedPosition 是相对于控件的光标位置.

relativeClickedPosition is the cursor position relative to the control.
