        private int pageSize = 10;

        private int pageIndex = 1;

然后是赋值 dataSource.DataSource = list;


#region 分页相关

        //分页操作

        private void PageOperation(ToolStripItemClickedEventArgs e)

        {

            if (e.ClickedItem.Text == "首页")

            {

                FirstPageOperation();

            }

            if (e.ClickedItem.Text == "上一页")

            {

                PrevPageOperation();

            }

            if (e.ClickedItem.Text == "下一页")

            {

                NextPageOperation();

            }

            if (e.ClickedItem.Text == "尾页")

            {

                LastPageOperation();

            }

        }

        //尾页

        private void LastPageOperation()

        {

            pageIndex = pageTotal;

            if (pageIndex + 1 >= pageTotal)

            {

                PageWithLastOfNext(false);

            }

            if (pageTotal > 1)

            {

                PageWithPrevOfFirst(true);

            }

        }

        //下一页

        private void NextPageOperation()

        {

            if (pageIndex + 1 >= pageTotal)

            {

                PageWithLastOfNext(false);

            }

            pageIndex++;

            if (pageTotal > 1)

            {

                PageWithPrevOfFirst(true);

            }

        }

        //上一页

        private void PrevPageOperation()

        {

            if (pageIndex - 1 <= 1)

            {

                PageWithPrevOfFirst(false);

            }

            pageIndex--;

            if (pageTotal > 1)

            {

                PageWithLastOfNext(true);

            }

        }

        //首页

        private void FirstPageOperation()

        {

            pageIndex = 1;

            if (pageIndex - 1 <= 1)

            {

                PageWithPrevOfFirst(false);

            }

            if (pageTotal > 1)

            {

                PageWithLastOfNext(true);

            }

        }


        private void PageWithPrevOfFirst(bool enabled)

        {

                    itemPagePrev.Enabled = enabled;

                    iitemPageFirst.Enabled = enabled;

        }


        private void PageWithLastOfNext(bool enabled)

        {

                    itemPageLast.Enabled = enabled;

                    itemPageNext.Enabled = enabled;
