存储过程分页，按多条件排序(原创)

cs页面调用代码：

 　public int TotalPage = 0;
    public int PageCurrent = 1;
    public int PageSize = 25;
    public int RowsCount = 0;
    string userid, username;
    public  DataTable dt = new DataTable();
    public string path, userwelcome;
    public string opt,cid;
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            if (Request.Params["page"] == null || Request.Params["page"].ToString().Equals(""))
                PageCurrent = 1;
            else
               PageCurrent=int.Parse(Request.Params["page"].ToString());
           this.getPage(out TotalPage, out RowsCount, PageSize, PageCurrent);           
        }
    }

//调用存储过程的函数

  private void getPage(out int totalPage, out int rowsCount, int pageSize, int currentPage)
    {
        SqlParameter[] parameters = {
                    new SqlParameter("@TotalPage", SqlDbType.Int,4),

                    };
        parameters[0].Direction = ParameterDirection.Output;
        parameters[1].Direction = ParameterDirection.Output;
        parameters[2].Value = pageSize;
        parameters[3].Value = currentPage;
        parameters[4].Value = "a.RLId,a.companyName,a.webSite,a.isRL,a.ordernum,a.isrl,a.userid";

        DataSet ds = Wm23Abc.DBUtility.DbHelperSQL.RunProcedure("getRecordByPage", parameters, "dt");
        dt = ds.Tables[0];
        totalPage = int.Parse(parameters[0].Value.ToString());
        rowsCount = int.Parse(parameters[1].Value.ToString());
    }

.aspx页面代码：

<table id="SXFSTable" style="100%;" class="table">
        <tr><td><b>公司名称</b></td><td><b>公司网址</b></td><td><b>认领状态</b></td></tr>
        <%for (int i = 0; i < dt.Rows.Count; i++)
