C# 如何在单击通知图标时以编程方式显示上下文菜单？

我有一个C#windows表单示例。我需要在鼠标左键单击时显示通知图标的上下文菜单。我已将所需代码的书写位置标记如下：

private void button1_Click(object sender, EventArgs e)
{
        //Need to show the context menu here
}

---

请帮忙

左键单击图标时显示菜单

private void NotifyIcon_MouseClick(object sender, MouseEventArgs e)
{
    if (e.Button == MouseButtons.Left)
    {
        MethodInfo methodInfo = typeof(NotifyIcon).GetMethod("ShowContextMenu",
            BindingFlags.Instance | BindingFlags.NonPublic);

        methodInfo.Invoke(this.notifyIcon, null);
    }
}

单击问题中的按钮时显示菜单

private void button1_Click(object sender, EventArgs e)
{
    //Need to show the context menu here
    MethodInfo methodInfo = typeof(NotifyIcon).GetMethod("ShowContextMenu",
        BindingFlags.Instance | BindingFlags.NonPublic);
    methodInfo.Invoke(this.notifyIcon, null);
}
