    深入分析CurrentPageIndex、RecordCount、 PageCount、 PageSize:
      
    pagecount:
      
    public int PageCount
    {
        get
        {
            if (this.RecordCount == 0)
            {
                return 1;
            }
            return (int) Math.Ceiling((double) (((double) this.RecordCount) / ((double) this.PageSize)));
        }
    }
    recordcount:
      
    public int RecordCount
    {
        get
        {
            if (this.cloneFrom != null)
            {
                return this.cloneFrom.RecordCount;
            }
            object obj2 = this.ViewState["Recordcount"];
            if (obj2 != null)
            {
                return (int) obj2;
            }
            return 0;
        }
        set
        {
            this.ViewState["Recordcount"] = value;
        }
    }
    CurrentPageIndex:
      
    public int CurrentPageIndex
    {
        get
        {
            if (this.cloneFrom != null)
            {
                return this.cloneFrom.CurrentPageIndex;
            }
            object obj2 = this.ViewState["CurrentPageIndex"];
            int num = (obj2 == null) ? 1 : ((int) obj2);
            if ((num > this.PageCount) && (this.PageCount > 0))
            {
                return this.PageCount;
            }
            if (num < 1)
            {
                return 1;
            }
            return num;
        }
        set
        {
            int pageCount = value;
            if (pageCount < 1)
            {
                pageCount = 1;
            }
            else if (pageCount > this.PageCount)
            {
                pageCount = this.PageCount;
            }
            this.ViewState["CurrentPageIndex"] = pageCount;
        }
    }
    PageSize:
      
    public int PageSize
    {
        get
        {
            int num;
            if ((!string.IsNullOrEmpty(this.UrlPageSizeName) && !base.DesignMode) && (int.TryParse(this.Page.Request.QueryString[this.UrlPageSizeName], out num) && (num > 0)))
            {
                return num;
            }
            if (this.cloneFrom != null)
            {
                return this.cloneFrom.PageSize;
            }
            object obj2 = this.ViewState["PageSize"];
            if (obj2 != null)
            {
                return (int) obj2;
            }
            return 10;
        }
        set
        {
            this.ViewState["PageSize"] = value;
        }
    }
