asp.net 操作cookie的简单实例

复制代码 代码如下:

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            HttpCookie cookie = Request.Cookies["loginInfo"];

if (cookie != null)
            {
                cb_repwd.Checked = true;
                tb_loginName.Text = UIHelper.Decrypt(cookie["loginName"]);
                tb_pwd.Attributes.Add("value", UIHelper.Decrypt(cookie["pwd"]));
            }
            else
            {
                tb_pwd.Attributes.Add("value", "******");
            }

        }

    }

protected void btn_login_Click(object sender, EventArgs e)
    {

if (UIHelper.GetString(Session["Code"]).ToUpper()!=this.tb_code.Text.Trim().ToUpper())
        {
            oJavaScript.Alert("验证码输入不正确");
            return;
        }

NetUserService NerService = ContextFactory.GetObject<NetUserService>("NetUserService");
        string sql = string.Format("from NetUser where LoginName='{0}'", tb_loginName.Text.Trim());
        IList<NetUser> list = NerService.Find(sql);
        if (list.Count > 0)
        {
            if (list[0].Status == 2)
            {
                oJavaScript.Alert("帐号已停用，请联系管理员");
                return;
            }
        }
