PageBarHelper分页显示类

一共有两个分页类,都可以使用(单独使用)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Common
{
public class PageBarHelper
{
/// <summary>
/// 计算数字页码条
/// </summary>
/// <param name="pageIndex">当前页码</param>
/// <param name="pageCount">总页数</param>
/// <returns></returns>
public static string GetPageBar(int pageIndex,int pageCount)
{
if (pageCount == 1)
{
return string.Empty;
}
//要求页面上要显示10个数字页码。
int start = pageIndex - 5;//计算起始位置
if (start < 1)
{
start = 1;
}
int end = start + 9;//计算终止位置.
if (end > pageCount)
{
end = pageCount;
start = end - 9<1?1:end-9;
}
StringBuilder sb = new StringBuilder();
if (pageIndex > 1)
{
sb.Append(string.Format("<a href='?pageIndex={0}' class='pageBarIndex'>上一页</a>", pageIndex - 1));
}
for (int i = start; i <= end; i++)
{
if (i == pageIndex)
{
sb.Append(i);
}
else
{
sb.Append(string.Format("<a href='?pageIndex={0}' class='pageBarIndex'>{0}</a>",i));
}
}
if (pageIndex < pageCount)
{
sb.Append(string.Format("<a href='?pageIndex={0}' class='pageBarIndex'>下一页</a>", pageIndex + 1));
}

return sb.ToString();
}
}
}
