大家可以测试一下看看怎么样

如果在使用中有问题，可以直接提出来

net_love

  //总页数
            winFormPage1.PageCount = winFormPage1.Count / winFormPage1.PageSize;

            if (winFormPage1.Count % winFormPage1.PageSize != 0)
                winFormPage1.PageCount = winFormPage1.PageCount + 1;
这些代码如果封装到分页控件里面会更好

//总页数
            winFormPage1.PageCount = winFormPage1.Count / winFormPage1.PageSize;

好的，谢谢建议会的

net_love

嗯，如果多次使用，这些代码都是重复的
