ASP.NET C# 后台输出的带页码的分页函数（不用控件）

分页，如果用JS在前台分页，我觉得对SEO不利（js这东西确实是个好东西，但有时候，得考滤SEO），所以写了个ASP.NET 不用控件进行分页，直接从后台输出的，带页码的分页函数，如果您有用，可以参考

进入页面时接收参数：

if (Request["page"] != null)

{

if (!int.TryParse(Request["page"].ToString(), out pageindex))

{

Response.End();

return;

}

}

分页时用到的字段，写在pageload上面

//分页用到的字段

protected int pageindex = 1;

protected int pagesize = 1;

protected int startIndex = 1;

protected int endIndex = 0;

protected int preIndex = 0;

protected int nextIndex = 0;

方法 ：

protected string FenYe(int pageindex, int pagesize)

{

StringBuilder sbFenye = new StringBuilder();

decimal rc = 0;

DataSet ds = GetData.XXXX;//这里是从后台获取的DataSet列表

if (ds != null && ds.Tables.Count > 0 && ds.Tables[0].Rows.Count > 0)

{

rc = decimal.Parse(ds.Tables[0].Rows[0][0].ToString());

int totalpage = Convert.ToInt32(Math.Ceiling(rc / pagesize).ToString());

nextIndex = pageindex + 1;

preIndex = pageindex - 1;

string nextStr = "";

string preStr = "";

if (nextIndex > totalpage)

{

nextStr = "";

}

else

{

nextStr = "<a href=\"default.aspx?page=" + nextIndex + "\"> 下一页 </a>";

}

if (pageindex == 1)

{

preStr = "";

}

else

{

preStr = "<a href=\"default.aspx?page=" + preIndex + "\"> 上一页 </a>";

}

sbFenye.Append("<div class=\"scott\">");

sbFenye.Append("总记录："+ rc +" 总页数："+totalpage+" ");

if (pageindex != 1)

{

sbFenye.Append("<a href=\"default.aspx?page=1\">首页</a>");

}

sbFenye.Append(preStr);

int Step = 5;

int LeftNum = 0;

int RightNum = 0;

if ((pageindex - Step) < 1)

{

LeftNum = 1;

}

else

{

LeftNum = pageindex - Step;

}

if ( (pageindex + Step) > totalpage)

{

RightNum = totalpage;

}

else

{

RightNum = pageindex + Step;

}

for (int i = LeftNum; i <= RightNum; i++)

{

if (i==pageindex)

{

sbFenye.Append("<span class=\"current\">" + i.ToString() + "</span>");

}

else

{

sbFenye.Append("<a href=\"default.aspx?page=" + i + "\">" +i.ToString() + "</a>");

}

}

sbFenye.Append(nextStr);

if (pageindex != totalpage)

{

sbFenye.Append("<a href=\"default.aspx?page=" + totalpage + "\">尾页</a>");

}

sbFenye.Append("</div>");

}

return sbFenye.ToString();

}

前台输出

<%=FenYe(pageindex,pagesize)%>

前台列表：

<%= PageList(pageindex,pagesize) %>

PageList为后台.cs里写的读取列表的方法

前台CSS样式：

DIV.scott {
PADDING-RIGHT: 3px; PADDING-LEFT: 3px; PADDING-BOTTOM: 3px; MARGIN: 3px; PADDING-TOP: 3px; TEXT-ALIGN: center
}
DIV.scott A {
BORDER-RIGHT: #ddd 1px solid; PADDING-RIGHT: 5px; BORDER-TOP: #ddd 1px solid; PADDING-LEFT: 5px; PADDING-BOTTOM: 2px; BORDER-LEFT: #ddd 1px solid; COLOR: #88af3f; MARGIN-RIGHT: 2px; PADDING-TOP: 2px; BORDER-BOTTOM: #ddd 1px solid; TEXT-DECORATION: none
}
DIV.scott A:hover {
