asp.net静态页面生成实例
打开速度较动态页面有明显提高；
二、有利于教程，baidu、google都会优先收录静态页面，不仅被收录的快还收录的全；
三、减轻服务器负担，浏览网页无需调用系统数据库；
四、网站更安全，html页面不会受asp相关漏洞的影响；
观看一下大一点的网站基本全是静态页面，而且可以减少攻击，防sql注入。数据库出错时，不影响网站正常访问。
生成html文章虽操作上麻烦些，程序上繁杂些，但为了更利于搜索，为了速度更快些，更安全，这些牺牲还是值得的。
//生成静态页
protected void gridview1_rowdeleting(object sender, gridviewdeleteeventargs e)
{
string n_id = this.gridview1.datakeys[e.rowindex]["nid"].tostring();
sqlconnection conn = new sqlconnection("server=.;uid=sa;pwd=;database=dress");
sqlcommand cmd = new sqlcommand("select nid,n_title,n_content,n_pic,n_date from p_news where nid="+n_id,conn);
conn.open();
sqldatareader dr = cmd.executereader();
//获取新闻发布的时间
string date = "";
if(dr.read())
{
date = convert.todatetime(dr["n_date"]).tostring("yyyymmddhhmmss_");
//调用静态生成的方法
transferstatic(dr["n_title"].tostring(), dr["n_content"].tostring(), dr["n_pic"].tostring(), date, n_id);
response.write("<script>alert('www.3ppt.com静态页面生成成功！');location='bulidstaticpage.aspx'</script>");
}
}
//转换静态方法
public bool transferstatic(string title,string content,string pic,string date,string nid)
{
//输出路径
string outpath = server.mappath("~/newdetails");
//简体中文
encoding encoding = encoding.getencoding("gb2312");
//读取模版文件
string htmlmodel = server.mappath("~/htmlmodel/newdetail.html");
streamreader sr = null;
streamwriter sw = null;
string str = "";//保存内容的字符串
try
{
sr=new streamreader(htmlmodel,encoding);
str=sr.readtoend();//从头读到尾
}
catch(exception e)
{
response.write(e.message);
response.end();
sr.close();
}
//删除指定的页面
protected void button2_click(object sender, eventargs e)
{
string path = server.mappath("~/newdetails");
file.delete(path + "//" + this.listbox1.selectedvalue);
//page.clientscript.registerclientscriptblock(this.gettype(), "信息处理", "<script>alert('删除成功！');location='bulidstaticpage.aspx'< /script>");
page.clientscript.registerstartups教程cript(this.gettype(), "信息处理", "<script>alert('删除成功！');location='bulidstaticpage.aspx'< /script>");
}
生成静态页列表
//得到静态页面的路径
public string htmlpath(datetime date,string nid)
{
string path = "newdetails/" + date.tostring("yyyymmddhhmmss_") + nid + ".html";
return path;
}
//生成静态列表
protected void button1_click(object sender, eventargs e)
{
sqlconnection conn = new sqlconnection("server=.;uid=sa;pwd=;database=dress");
sqldataadapter da = new sqldataadapter("select nid,n_title,n_content,n_pic,n_date from p_news",conn);
dataset ds = new dataset();
da.fill(ds);
string str = "";
for (int i = 0; i < ds.tables[0].rows.count;i++)
{
//取时间
string date = convert.todatetime(ds.tables[0].rows[i]["n_date"]).tostring("yyyymmddhhmmss_");
//取编号
string nid = ds.tables[0].rows[i]["nid"].tostring();
//构造文件名
string pagename = date + nid + ".html";
//构造字符串
str += "<tr><td width=360px>"+"<a href='newdetails/"+pagename+"'>"+ds.tables[0].rows[i]["n_title"].tostring()+"</a>"+"</td><td width=200px>"+ds.tables[0].rows[i]["n_date"].tostring()+"</td></tr>";
}
//调用转换方法生成静态页
transferstatic(str);
}
//生成静态页
public bool transferstatic(string strall)
{
//输出路径
string outpath = server.mappath("~/");
encoding encoding = encoding.getencoding("gb2312");
//读取模版文件
string htmlmode = server.mappath("~/htmlmodel/newslist.html");
streamreader sr = null;
streamwriter sw = null;
string str = "";
try
{
sr = new streamreader(htmlmode, encoding);
str = sr.readtoend();
}
catch (exception e)
{
response.write(e.message);
response.end();
sr.close();
}
//构造要生成的静态页面的名字
string pagename = "newslist.html";
//开始替换内容
str = str.replace("newslist", strall);
//写文件
try
{
sw = new streamwriter(outpath + pagename, false, encoding);
sw.write(str);//将字符串str写到文件
sw.flush();
}
catch (exception e)
{
response.write(e.message);
response.end();
}
finally
{
sw.close();
}
return true;
}
在前台绑定新闻标题和时间：
<table>
<asp:repeater id="repeater1" runat="server">
<itemtemplate>
<tr>
<td width="360px"><a href='<%# htmlpath(convert.todatetime(eval("n_date")),eval("nid").tostring())%>'><%# eval("n_title") %></a></td>
<td width="200px"><%# eval("n_date") %></td>
</tr>
</itemtemplate>
