本文实例讲述了asp.net实现简单分页的方法。分享给大家供大家参考。
具体实现方法如下：
复制代码 代码如下:/// <summary>
/// 分页内容
/// </summary>
/// <param name="size">页面大小</param>
/// <param name="count">页面数量</param>
/// <param name="currendIndex">当前页</param>
/// <param name="pattern">url模式：demo.aspx?page={0}</param>
/// <param name="target">窗口模式</param>
/// <returns></returns>
public static string get_pagenation(int size,
int count,
int currendIndex,
string pattern,
string target)
{
//1>打开窗口目标
target = string.IsNullOrEmpty(target) ? "_top" : target;
//2>总页数
int pageCount = count / size;
pageCount = pageCount * size == count ? pageCount : pageCount + 1;
//3>分页内容
StringBuilder strHtml = new StringBuilder();
strHtml.Append("<span class='pagenation'>");
#region 首部处理
if (currendIndex > 1)
{
strHtml.AppendFormat("<a href='1' target='{0}'>[首页]</a>", target);
strHtml.AppendFormat("<a href='{0}' target='{1}'>[上一页]</a>", string.Format(pattern, currendIndex - 1), target);
}
else
{
strHtml.Append("<span class='disabled'>[首页]</span> <span class='disabled'>[上一页]</span>");
}
#endregion
#region 中间部分
int i = 1;
int right = (currendIndex + 4) > pageCount ? pageCount : currendIndex + 4;
if (currendIndex > 6)
{
i = currendIndex - 5;
}
else
{
right = pageCount >= 10 ? 10 : pageCount;
}
for (; i <= right; i++)
{
if (i == currendIndex)
{
strHtml.AppendFormat("<font class='current'>{0}</font>", i);
strHtml.AppendLine();
continue;
}
strHtml.AppendFormat("<a href='{0}' target='{1}'>[{2}]</a>", string.Format(pattern, i), target, i);
strHtml.AppendLine();
}
#endregion
#region 尾部处理
if (currendIndex == pageCount)
{
strHtml.Append("<span class='disabled'>[下一页]</span><span class='disabled'>[末页]</span>");
strHtml.AppendFormat("总共({0})页", pageCount);
}
else
{
strHtml.AppendFormat("<a href='{0}' target='{1}'>[下一页]</a>", string.Format(pattern, currendIndex + 1), target);
strHtml.AppendFormat("<a href='{0}' target='{1}'>[末页]</a>", string.Format(pattern, pageCount), target);
strHtml.AppendFormat(" <label>总共({0})页</label>", pageCount);
}
#endregion
strHtml.Append("</span>");
return strHtml.ToString();
}
希望本文所述对大家的asp.net程序设计有所帮助。
