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;
    }
}
