asp.net - 在asp.net中测量互联网速度

Question

我正在开发一个需要根据互联网速度/带宽改变内容的网站。

在带宽较低的地方，Web 应用程序应该只显示纯文本，而对于正常带宽，则显示正常的网站。

几天以来我一直在考虑它，但我无法找到合适的解决方案。有没有一种简单的方法来检测 asp.net 中的带宽？

谢谢

Answer 1

按照给定的代码检查您的互联网连接速度添加命名空间

使用 System.Net；

在测试按钮单击事件上编写代码..

  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'.");            

    }
