C# 使用c显示想法列表#

我希望显示一个想法列表，而不是只显示每天变化的一个想法。有没有办法编辑我的代码，以秒数而不是新的一天来显示更改

如何编辑下面的代码

using System;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Utilities;

namespace TOTD.TOTD
{
    public partial class TOTDUserControl : UserControl
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            SPWeb oWebsite = SPContext.Current.Web;
            SPList oList = oWebsite.Lists["QOTD"];
            SPListItemCollection collItem = oList.GetItems("Thought", "AuthorImage", "AuthorName","Head");

            Random random = new Random();
            int RndItem = random.Next(1, collItem.Count + 1);
            int LastDay = 0;
            int TOTD = 0;
            int CurrentDay = DateTime.Now.DayOfYear;

            try
            {

                LastDay = int.Parse(Application["LastDay"].ToString());
                TOTD = int.Parse(Application["TOTD"].ToString());


                if (LastDay != CurrentDay)
                {

                    Application["LastDay"] = CurrentDay;
                    Application["TOTD"] = RndItem;
                    SPListItem oItem = collItem[RndItem - 1];
                    this.ImgAuthor.ImageUrl = SPEncode.HtmlEncode
                        (oItem["AuthorImage"].ToString().TrimEnd('?', '.', ',', ' '));
                    this.lblTOTD.Text = oItem["Thought"].ToString();
                    this.lblAuthor.Text = SPEncode.HtmlEncode(oItem["AuthorName"].ToString());
                    this.lblNext.Text = SPEncode.HtmlEncode(oItem["Head"].ToString());
                }

                else
                {
                    SPListItem oItem = collItem[TOTD - 1];
                    this.ImgAuthor.ImageUrl = SPEncode.HtmlEncode
                        (oItem["AuthorImage"].ToString().TrimEnd('?', '.', ',', ' '));
                    this.lblTOTD.Text = oItem["Thought"].ToString();
                    this.lblAuthor.Text = SPEncode.HtmlEncode(oItem["AuthorName"].ToString());
                    this.lblNext.Text = SPEncode.HtmlEncode(oItem["Head"].ToString());
                }

            }
            catch
            {
                Application["LastDay"] = CurrentDay;
                Application["TOTD"] = RndItem;
                SPListItem oItem = collItem[RndItem - 1];
                this.ImgAuthor.ImageUrl = SPEncode.HtmlEncode
                    (oItem["AuthorImage"].ToString().TrimEnd('?', '.', ',', ' '));
                this.lblTOTD.Text = oItem["Thought"].ToString();
                this.lblAuthor.Text = SPEncode.HtmlEncode(oItem["AuthorName"].ToString());
                this.lblNext.Text = SPEncode.HtmlEncode(oItem["Head"].ToString());
            }
        }
    }
}

只需保存相关的DateTime并使用方法：

可能是代替了最后一天=整数。。。。只要有LastTime=int。。。。如果当前时间大于一定的秒数，则显示所需的时间

if (DateTime.Now.Subtract(givenDate).TotalSeconds >= 1)
{
   Application["LastDay"] = DateTime.Now;
 // do stuff.
}...
