WinForm方法无权访问面板属性

Question

我尝试使用可扩展菜单制作WinForm应用。我试图创建一个方法来改变form1中的面板属性，但即使它不是，它也会看到该值为false？我收到消息框＆＃34;识别为假＆＃34;。而不是代码我宁愿一个很好的解释

private void JobSelectButton_Click(object sender, EventArgs e)
{
    //button to open a panel with "menu"
    if (jobPanel.Visible == false)
    {
        // the panel is visible from this point
        jobPanel.Visible = true;
    }
    else
    {
        jobPanel.Visible = false;
    }            
}

public void fla(bool flag)
{   //method inside form1 and it should make jobPanel.Visible = false             
    if (jobPanel.Visible == false)
        MessageBox.Show("recognition as false");
    else jobPanel.Visible = false;
}

private void notification_MouseClick(object sender, MouseEventArgs e)
{   // user control that will call the method
    caseNBvalue = lbl_caseNB.Text;
    profile f2 = new profile();

    f2.fla(true);
}
