private void frmLogin_FormClosed(object sender, FormClosedEventArgs e)
{
   if (e.CloseReason == CloseReason.UserClosing)
        //停止关闭,返回见面?????????????????????????????????????????               
}

就是如果按了控制览的关闭按钮或者ALT+F4,让关闭不起作用怎么实现????

formclosing事件里有e.cancel=true可以取消关闭,不过这样我用this.close()也关不了了啊.

e.CloseReason == CloseReason.UserClosing
用这个条件判断也不行啊
