asp.net實現簡單分頁實例

本文實例講述了asp.net實現簡單分頁的方法。分享給大家供大家參考。

具體實現方法如下：

代碼如下:/// <summary>
/// 分頁內容
/// </summary>
/// <param name="size">頁面大小</param>
/// <param name="count">頁面數量</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
    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();
}
