最近在学asp.net mvc3，与asp.net webForm比起来。确实能提高不少效率，特别是数据校验和数据源方面，基本上不用自己手写。但是总担心其entity framework框架，会不会影响程序运行效率，下面是我自己写的分页代码，欢迎大家指教
public ActionResult Index(int page)
{
int pageSize = 1;
var query=ob.news.OrderByDescending(news=>news.id).Skip(pageSize*(page-1)).Take(pageSize);
pageing pageInfo = new pageing();
pageInfo.pageSize = pageSize;
pageInfo.curentPage = page;
pageInfo.totalCount = ob.news.Count();
pageInfo.coustomUrl = "/news?";
ViewBag.Page = pageInfo;
return View(query);
}
public class pageing
{
/// <summary>
/// 每页数量
/// </summary>
public int pageSize { get; set; }
/// <summary>
/// 当前页
/// </summary>
public int curentPage{ get; set; }
/// <summary>
/// 总数量
/// </summary>
public int totalCount { get; set; }
/// <summary>
/// 定义页页连接
/// </summary>
public string coustomUrl { get; set; }
/// <summary>
/// 自定义页面参数名
/// </summary>
public string coustomPageParName { get; set; }
public string WrtiePage()
{
int totalPage = totalCount % pageSize == 0 ? totalCount / pageSize : totalCount / pageSize + 1;
if (totalPage>1)
{
StringBuilder strs = new StringBuilder();
strs.AppendFormat("<a href=\"{0}{1}={2}\">上一页</a> ", coustomUrl, string.IsNullOrEmpty(coustomPageParName) ? "page" : coustomPageParName, curentPage == 1 ? 1 : curentPage - 1);
for (int i = curentPage==1?1:curentPage-1; i <= curentPage+5; i++)
{
if (i == curentPage)
{
strs.AppendFormat("<span id='curentPage'>{0}</span> ",i);
}
else
{
strs.AppendFormat("<a href=\"{0}{1}={2}\">{2}</a> ", coustomUrl, string.IsNullOrEmpty(coustomPageParName) ? "page" : coustomPageParName, i);
}
if (i == totalPage || i==totalPage/5) { break; }
}
strs.AppendFormat("<a href=\"{0}{1}={2}\">下一页</a> ", coustomUrl, string.IsNullOrEmpty(coustomPageParName) ? "page" : coustomPageParName, curentPage == totalPage ? totalPage : curentPage + 1);
return strs.ToString();
}
return "";
}
}
}
