public static class PageHelper
{
/// <summary>
///
/// </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(string currentPageStr, int pageSize, int totalCount)
{
int currentPage = 1; //当前页
int.TryParse(currentPageStr, out currentPage); //与相应的QueryString绑定
var totalPages = Math.Max((totalCount + pageSize - 1) / pageSize, 1); //总页数
var dict = 0;
var output = new StringBuilder();

if (totalPages > 1)
{
if (currentPage != 1)
{ //处理首页链接
dict= 1;
output.AppendFormat("<a href='?p={0}'>首页</a>",dict);
}
if (currentPage > 1)
{ //处理上一页链接
dict= currentPage - 1;
output.AppendFormat("<a href='?p={0}'>上一页</a>",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 = currentPage + i - currint;
output.AppendFormat("<a href='?p={0}'>{1}</a>",dict,(currentPage + i - currint).ToString());
}
output.Append(" ");
}
}
if (currentPage < totalPages)
{ //处理下一页的链接
dict = currentPage + 1;
output.AppendFormat("<a href='?p={0}'>下一页</a>",dict);
}
else
{
output.Append("下一页");
}
output.Append(" ");
if (currentPage != totalPages)
{
dict = totalPages;
output.AppendFormat("<a href='?p={0}'>末页</a>",dict);
}
output.Append(" ");
}
output.AppendFormat("{0} / {1}", currentPage, totalPages); //统计
return output.ToString();
}
