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。
