方案1:
///
/// 传入URL返回网页的html代码
/// ///
URL
///
public static string getUrltoHtml(string Url)
{
errorMsg = "";
try
{
System.Net.WebRequest wReq = System.Net.WebRequest.Create(Url);
// Get the response instance.
System.Net.WebResponse wResp =wReq.GetResponse();
// Read an HTTP-specific property
//if (wResp.GetType() ==HttpWebResponse)
//{
//DateTime updated =((System.Net.HttpWebResponse)wResp).LastModified;
//}
// Get the response stream.
System.IO.Stream respStream = wResp.GetResponseStream();
// Dim reader As StreamReader = New StreamReader(respStream)
System.IO.StreamReader reader = new System.IO.StreamReader(respStream, System.Text.Encoding.GetEncoding("gb2312"));
return reader.ReadToEnd();
}
catch(System.Exception ex)
{
errorMsg = ex.Message ;
}
return "";
}
你可以用这个函数获取网页的客户端的html代码,然后保存到.html文件里就可以了。
方案2:
生成单个的静态页面不是难点,难的是各个静态页面间的关联和链接如何保持完整;特别是在页面频繁更新、修改、或删除的情况下;
像阿里巴巴的页面也全部是html的,估计用的是地址映射的功能关于地址映射可参考:http://www.easewe.com/Article/ShowArticle.aspx?article=131

ASP.Net生成静态HTML页
在Asp中实现的生成静态页用到的FileSystemObject对象!
在.Net中涉及此类操作的是System.IO
以下是程序代码 注:此代码非原创!参考别人代码
//生成HTML页
public static bool WriteFile(string strText,string strContent,string strAuthor)
{
string path = HttpContext.Current.Server.MapPath("/news/");
Encoding code = Encoding.GetEncoding("gb2312");
// 读取模板文件
string temp = HttpContext.Current.Server.MapPath("/news/text.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();
}
string htmlfilename=DateTime.Now.ToString("yyyyMMddHHmmss")+".html";
// 替换内容
// 这时,模板文件已经读入到名称为str的变量中了
str =str.Replace("ShowArticle",strText); //模板页中的ShowArticle
str = str.Replace("biaoti",strText);
str = str.Replace("content",strContent);
str = str.Replace("author",strAuthor);
// 写文件
try
{
sw = new StreamWriter(path + 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 true;
此函数放在Conn.CS基类中了在添加新闻的代码中引用 注:工程名为Hover
if(Hover.Conn.WriteFilethis.Title.Text.ToString),this.Content.Text.ToString),this.Author.Text.ToString)))
{
Response.Write("添加成功");
}
else
{
Response.Write("生成HTML出错!");
}
模板页Text.html代码
