深入分析CurrentPageIndex、RecordCount、 PageCount、 PageSize:

pagecount:

?
public int PageCount
{
    get
    {
        if(this.RecordCount == 0)
        {
            return1;
        }
        return(int) Math.Ceiling((double) (((double)this.RecordCount) / ((double)this.PageSize)));
    }
}

recordcount:

?
public int RecordCount
{
    get
    {
        if(this.cloneFrom !=null)
        {
            returnthis.cloneFrom.RecordCount;
        }
        objectobj2 =this.ViewState["Recordcount"];
        if(obj2 !=null)
        {
            return(int) obj2;
        }
        return0;
    }
    set
    {
        this.ViewState["Recordcount"] = value;
    }
}

CurrentPageIndex:

?
public int CurrentPageIndex
{
    get
    {
        if(this.cloneFrom !=null)
        {
            returnthis.cloneFrom.CurrentPageIndex;
        }
        objectobj2 =this.ViewState["CurrentPageIndex"];
        intnum = (obj2 ==null) ? 1 : ((int) obj2);
        if((num >this.PageCount) && (this.PageCount > 0))
        {
            returnthis.PageCount;
        }
        if(num < 1)
        {
            return1;
        }
        returnnum;
    }
    set
    {
        intpageCount = value;
        if(pageCount < 1)
        {
            pageCount = 1;
        }
        elseif(pageCount > this.PageCount)
        {
            pageCount =this.PageCount;
        }
        this.ViewState["CurrentPageIndex"] = pageCount;
    }
}

PageSize:

?
public int PageSize
{
    get
    {
        intnum;
        if((!string.IsNullOrEmpty(this.UrlPageSizeName) && !base.DesignMode) && (int.TryParse(this.Page.Request.QueryString[this.UrlPageSizeName],outnum) && (num > 0)))
        {
            returnnum;
        }
        if(this.cloneFrom !=null)
        {
            returnthis.cloneFrom.PageSize;
        }
        objectobj2 =this.ViewState["PageSize"];
        if(obj2 !=null)
        {
            return(int) obj2;
        }
        return10;
    }
    set
    {
        this.ViewState["PageSize"] = value;
    }
}
