在文章发布系统中采用服务器端生成静态页面的方法可以有效减轻服务器的负担,特别是对大流量网站非常有效。但是既然生成的是静态页面,生成时是什么样,显示就是什么样了,对于文章常见文章被阅读次数怎么显示呢?

例见:

以下是ShowArticle.aspx.cs中调用Hover.Conn的类的代码
---------------------start conn.cs----------------------------------
//并非全部conn.cs代码,只列出了ShowArticle.aspx调用到的代码

public static bool WriteCounter(string strText,string strContent,string strAuthor,string click, string filename)

         {

              Encoding code = Encoding.GetEncoding("gb2312");

              string path=HttpContext.Current.Server.MapPath("/news/"+filename);

              // 读取模板文件

              string temp = HttpContext.Current.Server.MapPath("/news/template/template.html");

              //string temp = HttpContext.Current.Server.MapPath("/news/"+filename);

       //这里有个疑问.我用string temp = HttpContext.Current.Server.MapPath("/news/"+filename);
              //这是选择模板时选择已生成的文件利用它做模板,这样的话下面的替换str变量我就只写
             //str = str.Replace("$ClickCounter$",click);这一句就够了,但选择已生成的文件做模板总报该进程无法访问文
  //件“D:\Hover\news\2004\04\21\20040421215951.html”,因为该文件正由另一进程使用。未将对象引用设置到对象的实例
//这难道是此方法读选模板后再写此文件,这样不可以再由另一进程使用吗。这里还是不清楚呀!

             
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 addtime=DateTime.Now.ToString();

              // 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("$ClickCounter$",click);

              str = str.Replace("$Title$",strText);

              str = str.Replace("$Content$",strContent);

              str = str.Replace("$Author$",strAuthor);

              str = str.Replace("$AddTime$",addtime);

             

              // 写文件

              try

              {

                   sw = new StreamWriter(path , false, code);

                   sw.Write(str);

                   sw.Flush();

              }

              catch(Exception ex)

              {

                   HttpContext.Current.Response.Write(ex.Message);

                   HttpContext.Current.Response.End();

              }

              finally

              {

                   sw.Close();

              }

              sw.Close();

              sr.Close();

              return true;      

         }

//验证输入id是否为非法参数

         public bool checkid(string str)

         {

 

              try

              {

                   int i=int.Parse(str); 

              }

              catch

              {

                   return false;

              }

              return true;

         }

终于自己解决了一个问题。记录一下。哪位兄弟有别的方法实现一起交流一下,再有
上面红色字的部分。哪位讲一下,我还是不很清楚呀!在HTML页面中实现点击数统计 For ASP.Net版! (费事版)
