Web页面实现后台数据处理进度与剩余时间的显示

    1、页面后台代码添加如下属性：

/// <summary>
/// 总数
/// </summary>
private double total
{
    set
    {
        Session["DPMS.POP.POP_ExcelLeadIn_total"] = value;
    }
    get
    {
        if (Session["DPMS.POP.POP_ExcelLeadIn_total"] == null)
        {
            return 0;
        }
        return Convert.ToDouble(Session["DPMS.POP.POP_ExcelLeadIn_total"]);
    }
}
/// <summary>
/// 当前进度
/// </summary>
private int cur
{
    set
    {
        Session["DPMS.POP.POP_ExcelLeadIn_cur"] = value;
    }
    get
    {
        if (Session["DPMS.POP.POP_ExcelLeadIn_cur"] == null)
        {
            return 0;
        }
        return Convert.ToInt32(Session["DPMS.POP.POP_ExcelLeadIn_cur"]);
    }
}
/// <summary>
/// 错误信息
/// </summary>
private string errMsg
{
    set
    {
        Session["DPMS.POP.POP_ExcelLeadIn_errMsg"] = value;
    }
    get
    {
        if (Session["DPMS.POP.POP_ExcelLeadIn_errMsg"] == null)
        {
            return string.Empty;
        }
        return Session["DPMS.POP.POP_ExcelLeadIn_errMsg"].ToString();
    }
}
/// <summary>
/// 开始时间
/// </summary>
private DateTime startTime
{
    set
    {
        Session["DPMS.POP.POP_ExcelLeadIn_startTime"] = value;
    }
    get
    {
        if (Session["DPMS.POP.POP_ExcelLeadIn_startTime"] == null)
        {
            return DateTime.Now;
        }
        return Convert.ToDateTime(Session["DPMS.POP.POP_ExcelLeadIn_startTime"]);
    }
}
