当我单击很多次时，我的臀部会崩溃/冻结 [英] My buttom crashes / freezen when i click a lot of times

问题描述

你好

我正在Windows窗体中做一个项目，问题是当我在菜单的按钮中多次单击时，它在内存中出现了Mb的lof现象，第一张图片是我仅完成操作时的情况单击，在内存中有25MB，然后在第二张照片中 进行了将近50次点击，我获得了90 MB以上的空间:       

I am doing a project in Windows Form, and the problem is that when i click a lot of times in a button of my menu, it get a lof of Mb in the memory, the first picture is when i have done only a click, with 25MB in the memory, then in the second photo i have done almost 50 clicks, and i get more of 90 MB:       

        {
            LoginForm loginform = new LoginForm();
            sql.authenticated = true;
            authenticated.AddFormToPanel(loginform, panelcenter);
            sql.authenticated = false;
        }

^^是按钮的代码，它生成一个表单，该代码是:

^^ Is the code of the button, It generates a form, which code is:

using System;
using System.Windows.Forms;

namespace Marks_Gestionator
{
    public partial class LoginForm : Form
    {
        public LoginForm()
        {
            InitializeComponent();
        }
        private void btConnect_Click(object sender, EventArgs e)
        {
            sql.login_sqlcmd(string.Format("SELECT password from users WHERE username = '{0}';", box_login_username.Text));
            md5.MD5encode(box_login_password.Text);
            if (sql.password == md5.passwordmd5)
            {
                MessageBox.Show("Connected.");
                sql.authenticated = true;
            }
            else
            {
                MessageBox.Show("Password is not correct.");
                sql.authenticated = false;
            }
        }
    }
}

另一方面，我的应用发生崩溃，它的开头为30MB，

On the other hand, my app get a crash in other part, it starts with 30MB, 

它向我报告了这个错误:

And it reports me this mistake:

推荐答案

您是否考虑过使用try/finally禁用按钮，以便在尝试之前禁用按钮，请在尝试中进行操作，最后再启用.

Have you considered disabling the button using a try/finally so that prior to the try, disable the button, do work in the try, re-enable in the finally.

当然，您可以取消订阅工作，然后通过尝试/最终设置再次订阅click事件.

Of course you could un-subscribe do work then subscribe back to the click event, again with a try/finally setup.
