c# - 如何在 ASP.Net Web 应用程序中运行后台进程

Question

我想在我的 web 应用程序中执行一些功能，而不像 windows 应用程序中的后台进程一样向用户提示正在运行的进程。

我想在用户点击时触发后台进程，也想向这些函数发送一些数据。

有人可以建议我如何执行此操作吗？

private readonly BackgroundWorker backgroundWorker1 = new BackgroundWorker();

protected void Page_Load(object sender, EventArgs e)
    {
        this.backgroundWorker1.DoWork += new System.ComponentModel.DoWorkEventHandler(this.backgroundWorker1_DoWork);
    }

    private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
    {
        try
        {
            timing();
        }
        catch
        {
        }
    }

    public void timing()
    {
        string tt = DateTime.Now.ToString("tt");
        string t = "";
        if (tt == "AM")
        {
            int hour = DateTime.Now.Hour;
            if ((hour >= 0) & (hour <= 11))
            {
                t = "GOOD MORNING";
            }
        }
        else if (tt == "PM")
        {
            int hour = DateTime.Now.Hour;
            if ((hour >= 12) & (hour <= 15))
            {
                t = "GOOD AFTERNOON";
            }
            else if ((hour >= 16) & (hour <= 23))
            {
                t = "GOOD EVENING";
            }
        }
        Label1.Text = t;
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        backgroundWorker1.RunWorkerAsync();
    }
