asp.net實現(xiàn)簡單分頁實例

    本文實例講述了asp.net實現(xiàn)簡單分頁的方法。分享給大家供大家參考。
    具體實現(xiàn)方法如下：
    復制代碼 代碼如下:/// <summary>
    /// 分頁內容
    /// </summary>
    /// <param name="size">頁面大小</param>
    /// <param name="count">頁面數(shù)量</param>
    /// <param name="currendIndex">當前頁</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>打開窗口目標
    target = string.IsNullOrEmpty(target) ? "_top" : target;
    //2>總頁數(shù)
    int pageCount = count / size;
    pageCount = pageCount * size == count ? pageCount : pageCount + 1;
    //3>分頁內容
    StringBuilder strHtml = new StringBuilder();
    strHtml.Append("<span class='pagenation'>");
    #region 首部處理
    if (currendIndex > 1)
    {
    strHtml.AppendFormat("<a href='1' target='{0}'>[首頁]</a>", target);
    strHtml.AppendFormat("<a href='{0}' target='{1}'>[上一頁]</a>", string.Format(pattern, currendIndex - 1), target);
    }
    else
    {
    strHtml.Append("<span class='disabled'>[首頁]</span> <span class='disabled'>[上一頁]</span>");
    }
    #endregion
    #region 中間部分
    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 尾部處理
    if (currendIndex == pageCount)
    {
    strHtml.Append("<span class='disabled'>[下一頁]</span><span class='disabled'>[末頁]</span>");
    strHtml.AppendFormat("總共({0})頁", pageCount);
    }
    else
    {
    strHtml.AppendFormat("<a href='{0}' target='{1}'>[下一頁]</a>", string.Format(pattern, currendIndex + 1), target);
    strHtml.AppendFormat("<a href='{0}' target='{1}'>[末頁]</a>", string.Format(pattern, pageCount), target);
    strHtml.AppendFormat(" <label>總共({0})頁</label>", pageCount);
    }
    #endregion
    strHtml.Append("</span>");
    return strHtml.ToString();
    }
    希望本文所述對大家的asp.net程序設計有所幫助。
