生成靜態頁面的主要作用是提高頁面的訪問效率
生成HTML方法主要步驟只有兩個：
一、獲取要生成的html文件的內容
二、將獲取的html文件內容保存爲html文件
1. 生成一個模板頁面:template.html
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN""http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>$Title</title>
</head>
<body>
<div style="width: 417px; height: 54px; font-size: 30px; color: red;" align="center">
<br />
$Title</div>
<div style="width: 417px; height: 8px; color: gray;">
瀏覽<font color="red">1</font>次 $Time</div>
<div style="width: 417px; height: 100px">
$Content</div>
<div style="width: 416px; height: 9px">
$Pager</div>
<div style="width: 416px; height: 8px">
<form id="form1" action="/demo/aaa.aspx" method="post" style="margin:0px">
<input id="Text1" name="Text1" type="text" /><Img id="Image1" src="../UserInfo/CheckCode.aspx"/><br />
<textarea id="CommentContent" cols="20" rows="2"></textarea>
<br />
<input id="NewsId" type="hidden" value="$NewsId"/>
<input id="Button1" type="submit" value="button" />
<a href="../Display.aspx?NewsId=$NewsId">查看更多評論</a></form>
</div>
</body>
</html>
2.添加新聞的頁面:AddNews.aspx
protected void Button1_Click(object sender, EventArgs e)
{
//生成一個字符串:"當前年月日//當前年月日時分秒"
string strDate = DateTime.Now.ToString("yyMMdd") + "//" + DateTime.Now.ToString("yyyymmddhhmmss");
//生成一個文件名:"當前年月日//當前年月日時分秒.html"
string strFileName = strDate + ".html";
string strTitle = Title.Text; //接收傳過來的新聞標題
string strContent = Content.Text; //接收傳過來的新聞內容
string[] content = strContent.Split(new Char[] { '|' });//對新聞內容進行拆分，並保存到數組
int upbound = content.Length;//數組的上限
DBHelper db = new DBHelper();
bool success = db.Execute("insert into News(Title,Content,FilePath)values('" + strTitle + "','" + strContent + "','" + strFileName + "')");
//if (success)
// Message.Text = "添加成功！";
/**/
///////////////////////////創建當前日期的文件夾開始
string dir = Server.MapPath("NewsFiles/" + DateTime.Now.ToString("yyMMdd"));//產生"NewsFiles//當前年月日"的物理路徑
//判斷該文件夾是否存在
if (!Directory.Exists(dir))
{
Directory.CreateDirectory(dir);//如果不存在,創建該文件夾
}
/**/
///////////////////////////創建當前日期的文件夾結束
try
{
for (int i = 0; i < content.Length; i++)
{
StringBuilder strhtml = new StringBuilder();
//獲取模板頁(NewsFiles/template.html)的位置
string fileName = Server.MapPath("NewsFiles/") + "template.html";
//創建StreamReader對象
using (StreamReader sr = new StreamReader(fileName, Encoding.GetEncoding("gb2312")))
{
String oneline;
//讀取指定的HTML文件模板,並將內容追加到strhtml中
while ((oneline = sr.ReadLine()) != null)
{
strhtml.Append(oneline);
}
sr.Close();
}
//爲標記數組賦值
//SqlServerDataBase db = new SqlServerDataBase();
DataSet ds = db.Select("select top 1 NewsId from News order by NewsId desc");//獲取id
string strTable = "<table><tr><td>$upUrl</td><td>$Number</td><td>$downUrl</td></tr></table>";//上下頁表格，注意此處的$upUrl（上一頁），$Number（頁碼分頁），$downUrl（下一頁）
//這三個是用來替換的。
string FilePath = "";
strhtml = strhtml.Replace("$Title", strTitle);
strhtml = strhtml.Replace("$NewsId", ds.Tables[0].Rows[0]["NewsId"].ToString());
strhtml = strhtml.Replace("$Time", DateTime.Now.ToString("yyyy/MM/dd"));
strhtml = strhtml.Replace("$Content", content[i]);
string strNumber = "";//數字分頁1，2，3……
for (int m = 1; m <= upbound; m++)
{
if (m == 1)//如果是第一頁就顯示成這個樣子：20070524.html而不是20070524_1.html
strNumber = strNumber + " [" + "<a href=../" + strDate + ".html" + ">" + m + "</a>" + "] ";
else
{
int n = m - 1;//第三頁的連接應該是20070524_2.html，以此類推
strNumber = strNumber + " [" + "<a href=../" + strDate + "_" + n + ".html" + ">" + m + "</a>" + "] ";
}
}
if (upbound == 0)//如果沒有分頁，就直接按日期時間保存
{
FilePath = "NewsFiles" + "//" + strDate + ".html";
strhtml = strhtml.Replace("$Pager", "");
}
else//否則按20070524.html、20070524_1.html 這種效果保存
{
if (i == 0)
FilePath = "NewsFiles//" + strDate + ".html";
else
FilePath = "NewsFiles//" + strDate + "_" + i + ".html";

strTable = strTable.Replace("$upUrl", "<a href=../" + strDate + "_" + p + ".html" + ">上一頁</a>");
}
if (upbound == 1)//如果只有一頁，則不顯示頁碼
//strNumber="";
strTable = strTable.Replace("$Number", "");
else
strTable = strTable.Replace("$Number", strNumber);//頁碼替換
/**/
////////////////////////
if (i == upbound - 1)//最後一頁不顯示下一頁

}
//創建文件信息對象
FileInfo finfo = new FileInfo(Server.MapPath(FilePath));
//以打開或者寫入的形式創建文件流
using (FileStream fs = finfo.OpenWrite())
{
//根據上面創建的文件流創建寫數據流
StreamWriter sw = new StreamWriter(fs, System.Text.Encoding.Default);
//把新的內容寫到創建的HTML頁面中
sw.WriteLine(strhtml.ToString());
sw.Flush();
sw.Close();
}
}
}
catch (Exception err)
{

Response.Write(err.ToString());
