c# - ASP NET 以间隔更新标签，取决于代码隐藏处增加的 INT

Question

我正在尝试为此寻找解决方案。

我有启动 foreach 的按钮，通过 API 插入一些记录，大约需要 2-6 分钟。与此同时，我加载了 gif 和消息（到目前为止效果很好），在 foreach 循环中我得到了 int++，所以我知道到目前为止我处理了多少条记录 - 这个 int 我需要以更新间隔显示在 aspx 页面中，以便用户可以看到如何迄今为止处理了许多记录。

页面

            <asp:UpdatePanel ID="processedUpdate" runat="server">
                <ContentTemplate>
                    <div class="row">
                        <div class="col-sm-12" style="text-align: center">
                            Processed:
                            <asp:Label ID="lblProcDone" runat="server"></asp:Label>
                            /
                            <asp:Label ID="lblProcLeft" runat="server"></asp:Label>
                        </div>
                    </div>
                </ContentTemplate>
                <Triggers>
                    <asp:AsyncPostBackTrigger ControlID="timerProcessed" EventName="Tick" />
                </Triggers>
            </asp:UpdatePanel>

        public int progressedItems = 0;
        public int emailsCountAll = 0;

        protected void btnUpdateContactsMailchimp_Click(object sender, EventArgs e)

            emailsCountAll = ls.Count;



            //for each

                JsonObject jobj = new JsonObject();
                jobj.Add("email_address", item);
                jobj.Add("status", "subscribed");
                request.AddParameter("undefined", jobj.ToString(), ParameterType.RequestBody);
                IRestResponse response = client.Execute(request);
                request.Parameters.Clear();
                if (response.StatusCode.ToString() == "OK")
                {
                    emailImportCount++;
                }
                else
                {
                    emailNotImportCount++;
                }
                progressedItems++;

            timerProcessed.Enabled = false;

            alertDuplicityMailImport.Visible = true;
            alertSuccessMailImport.Visible = true;
        }

        protected void timerProcessed_Tick(object sender, EventArgs e)
        {
            lblProcDone.Text = progressedItems.ToString();
            lblProcLeft.Text = emailsCountAll.ToString();
        }

最好的问候 Jakub，谢谢。
