调用公共类：
----------------------------------------------------------------------------
protected void Button2_Click(object sender, EventArgs e)
{
string NewsTitle = this.TextBox1.Text;
string NewsKindName = this.DropDownList1.SelectedItem.Text;
string NewsBody = this.WebEditor1.Text;
DateTime PubTime = DateTime.Now;
string UserName = Session["UserName"].ToString();
Response.Write(NewsKindName);
string[] strNewsHtml = new string[] { NewsTitle, NewsKindName, NewsBody, PubTime.ToString(), UserName };
string[] strOldHtml = new string[] { "@Title", "@NewsKInd", "@NewsBody", "@PubTime", "@UserName" };
string strFileName = DateTime.Now.ToString("ddhhmmss") + ".html";
string strFilePath = string.Format("NewsHtml/{0}", strFileName);
try
{
if (WriteFile.createHtml(strNewsHtml, strOldHtml, "mode.htm", strFilePath))
{
this.Label1.Text = "生成成功！";
}
else
{
this.Label1.Text = "生成失败！";
}

}
catch
{
this.Label1.Text = "生成失败！";
}
}

protected void Button3_Click(object sender, EventArgs e)
{
string[] strNewsHtml=new string[]{"鑫少爷到此一游！"};
string[] strStartHtml=new string[]{"<!-- start -->"};
string[] strEndHtml=new string[]{"<!--end-->"};
if (WriteFile.UpdateHtmlPage(strNewsHtml, strStartHtml, strEndHtml, "NewsHtml/02011139.html"))
{
this.Label1.Text="生成首页成功！";
}
else
{
this.Label1.Text="生成首页失败！";
}
}

新建文件夹NewsHtml,生成html文件放在里面
-----------------------------------------------------------

增加一个模板文件

<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<title>无标题页</title>
</head>
<body>
<table border="1" cellpadding="0" cellspacing="0" style="width: 522px; height: 338px">
<tr>
<td align="center" colspan="2">
@Title</td>
</tr>
<tr>
<td align="center" colspan="2">
发布人：@UserName     发布时间:@PubTime      新闻类别：@NewsKInd</td>
</tr>
<tr>
<td colspan="2">
@NewsBody</td></tr><tr>
<td style="WIDTH: 100px">
</td><td style="WIDTH: 100px" >
</td></tr></table></body></html>
