我这里带了参数，原因是这个函数会被带有不同条件参数的方法调用

 int Count;

    public void Newslistpage(string strwhere)

    {

       

        DataTable ds = new DataTable();

        int _currentpageindex = 1;

        if (!string.IsNullOrEmpty(Request["Page"]))

            _currentpageindex = int.Parse(Request["Page"]);

        if (strwhere=="")

        {

            ds = WebHelp.DALHelper.GetmuchList("tb_News", "tb_NewsClass", " * ", "Newsid", "Nclassid", "Nclassid", AspNetPager1.PageSize, _currentpageindex, "Newsid desc", " subjectid=1 ", "*", out Count).Tables[0];

        }

        else if (WebHelp.CRCommon.isNumber(Request.QueryString["nclassid"]) == false)

        {

            lmges.Visible = true;

        }

        else

        {

            ds = WebHelp.DALHelper.GetmuchList("tb_News", "tb_NewsClass", " * ", "Newsid", "Nclassid", "Nclassid", AspNetPager1.PageSize, _currentpageindex, "Newsid desc", " subjectid=1 and " + strwhere + " ", "*", out Count).Tables[0];

        }

        AspNetPager1.RecordCount = Count;

        AspNetPager1.CustomInfoHTML = "共" + AspNetPager1.RecordCount.ToString() + "条,";

        AspNetPager1.CustomInfoHTML += "" + AspNetPager1.PageCount.ToString() + "页,";

        AspNetPager1.CustomInfoHTML += "第" + _currentpageindex + "页";

        if (ds.Rows.Count > 0)

        {

            this.Rp_newslist.DataSource = ds;

            this.Rp_newslist.DataBind();

        }

        else

        {

            lmges.Visible = true;

        }

    }
