asp.net 将数据静态化

 

protected void Page_Load(object sender, EventArgs e)
        {

　　　　　　LoadHtml();

　　　}

 

 

数据从何而来??

#region 内容的读取   解释:如果已经静态化过了,就从  生成的静态文件获取数据,如果是第一次,就从数据源获取文件, 然后将其,第一次静态化

        {
            string content = Tool.FileHelper.ReadFile(filePath); --注意,tool是我们自己定义的公共库,ReadFile只是读取文件的方法
            return content;
        }
