在asp.net中测量internet速度

我正在开发一个网站，它需要根据互联网速度/带宽来改变内容

在带宽较低的地方，web应用程序应该只显示 纯文本，对于正常带宽，显示正常网站

几天来我一直在考虑这个问题，但我还没有找到一个合适的解决办法。 在asp.net中是否有一种检测带宽的简单方法

谢谢

请查看以下链接，希望您能从服务请求中了解有关带宽检查的想法

按照给定的代码检查您的internet连接速度 添加名称空间

Net系统

在测试按钮上写入代码单击事件

  Uri URL = new Uri("http://sixhoej.net/speedtest/1024kb.txt");

    WebClient wc = new WebClient();

    double starttime = Environment.TickCount;


    // download file from the specified URL, and save it to C:\speedtest.txt

    wc.DownloadFile(URL, @"C:\speedtest.txt");


    // get current tickcount

    double endtime = Environment.TickCount;


    // how many seconds did it take?

    // we are calculating this by subtracting starttime from endtime

    // and dividing by 1000 (since the tickcount is in miliseconds.. 1000 ms = 1 sec)

    double secs = Math.Floor(endtime - starttime) / 1000;


    // round the number of secs and remove the decimal point

    double secs2 = Math.Round(secs, 0);





    // calculate download rate in kb per sec.

    // this is done by dividing 1024 by the number of seconds it

    // took to download the file (1024 bytes = 1 kilobyte)

    double kbsec = Math.Round(1024 / secs);

    Label1.Text = "Download rate: " + kbsec + " kb/sec";

    try

    {

        // delete downloaded file

        System.IO.File.Delete(@"C:\speedtest.txt");

         Response.Write("Done.");

    }

    catch

    {

        Response.Write("Couldn't delete download file.");

         Response.Write("To delete the file yourself, go to your C-drive and look for the file 'speedtest.txt'.");            

    }
