C# 之 HttpResponse 类

      Response 对象，派生自HttpResponse 类，该类封装来自 ASP.NET 操作的 HTTP 响应信息。存在于System.Web命名空间下。

      注：MIME(Multipurpose Internet Mail Extensions)多用途互联网邮件扩展类型就是设定某种扩展名的文件用一种应用程序来打开的方式类型，当该扩展名文件被访问的时候，浏览器会自动使用指定应用程序来打开。多用于指定一些客户端自定义的文件名，以及一些媒体文件打开方式。 

      （一）构造函数：public HttpResponse(TextWriter writer)
