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;

    }

}
