本文实例讲述了Asp.net(C#)读取数据库并生成JS文件制作首页图片切换效果的方法。,具体如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Text;
using System.IO;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
/// <summary>
/// 利用模板生成静态页面
/// </summary>
/// <param name="strTitle">标题</param>
/// <param name="strText">作者</param>
/// <param name="strContent">发布时间</param>
/// <param name="strAuthor">内容</param>
/// <returns>生成页面名称</returns>
public static string WriteFile(string strTitle, string strAuthor, string strDate, string strContent)
{
string path = HttpContext.Current.Server.MapPath("~/");
Encoding code = Encoding.GetEncoding("gb2312");
// 读取模板文件
string temp = HttpContext.Current.Server.MapPath("~/Template.html");
StreamReader sr = null;
StreamWriter sw = null;
string str = "";
try
{
sr = new StreamReader(temp, code);
str = sr.ReadToEnd(); // 读取文件
}
catch (Exception exp)
{
HttpContext.Current.Response.Write(exp.Message);
HttpContext.Current.Response.End();
sr.Close();
}
Random rd = new Random();
string strRd = rd.Next(0, 9999).ToString();
string htmlfilename = DateTime.Now.ToString("yyyyMMddHHmmss") + strRd + ".html";
DateTime dtNow = DateTime.Now;
// 替换内容
str = str.Replace("$biaoti", strTitle);
str = str.Replace("$author", strAuthor);
str = str.Replace("$datetime", strDate);
str = str.Replace("$content", strContent);
// 写文件
try
{
string pathUrl = path + dtNow.Year + "" + dtNow.Month + "" + dtNow.Day;
if (!Directory.Exists(pathUrl))
{
Directory.CreateDirectory(pathUrl);
}
sw = new StreamWriter(pathUrl + "" + htmlfilename, false, code);
sw.Write(str);
sw.Flush();
}
catch (Exception ex)
{
HttpContext.Current.Response.Write(ex.Message);
HttpContext.Current.Response.End();
}
finally
{
sw.Close();
}
return dtNow.Year.ToString() + "/" + dtNow.Month.ToString() + "/" + dtNow.Day.ToString() + "/" + htmlfilename;
}
protected void Button1_Click(object sender, EventArgs e)
{
WriteFile("title" , "ttttttt" , "2011-09-27", "测试 <br>");
}
}
Template.html
<table>
<tr>
<td align="center">$biaoti</td>
</tr>
<tr>
<td align="center">作者:$author 发布时间:$datetime</td>
</tr>
<tr>
<td>$content</td>
</tr>
</table>
思路:首先读取数据库中图片,链接,说明文字等数据,然后将读取到的数据写入首页图片切换效果的JS文件。
