asp.net mvc 的几种分页Pager

第一种

/// <summary>

/// 分页Pager显示
/// </summary>
/// <param name="html"></param>
/// <param name="currentPageStr">标识当前页码的QueryStringKey</param>
/// <param name="pageSize">每页显示</param>
/// <param name="totalCount">总数据量</param>
/// <returns></returns>
public static string Pager(this HtmlHelper html, string currentPageStr, int pageSize, int totalCount)
{
var queryString = html.ViewContext.HttpContext.Request.QueryString;
int currentPage = 1; //当前页
int.TryParse(queryString[currentPageStr], out currentPage); //与相应的QueryString绑定
var totalPages = Math.Max((totalCount + pageSize - 1) / pageSize, 1); //总页数
var dict = new RouteValueDictionary(html.ViewContext.RouteData.Values);

var output = new StringBuilder();

foreach (string key in queryString.Keys)
if (queryString[key] != null && !string.IsNullOrEmpty(key))
dict[key] = queryString[key];
if (totalPages > 1)
{
if (currentPage != 1)
{//处理首页连接
dict["p"] = 1;
output.AppendFormat("{0} ", html.RouteLink("首页", dict));
}
if (currentPage > 1)
{//处理上一页的连接
dict["p"] = currentPage - 1;
output.Append(html.RouteLink("上一页", dict));
}
else
{
output.Append("上一页");
}
output.Append(" ");
int currint = 5;
for (int i = 0; i <= 10; i++)
{//一共最多显示10个页码，前面5个，后面5个
if ((currentPage + i - currint) >= 1 && (currentPage + i - currint) <= totalPages)
if (currint == i)
{//当前页处理
output.Append(string.Format("[{0}]", currentPage));
}
else
{//一般页处理
dict["p"] = currentPage + i - currint;
output.Append(html.RouteLink((currentPage + i - currint).ToString(), dict));
}
output.Append(" ");
}
if (currentPage < totalPages)
{//处理下一页的链接
dict["p"] = currentPage + 1;
output.Append(html.RouteLink("下一页", dict));
}
else
{
output.Append("下一页");
}
output.Append(" ");
if (currentPage != totalPages)
{
dict["p"] = totalPages;
output.Append(html.RouteLink("末页", dict));
}
output.Append(" ");
}
output.AppendFormat("{0} / {1}", currentPage, totalPages);//这个统计加不加都行
return output.ToString();
}
