asp.net实现简单分页实例

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：

/// <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();
}
