How to Check Internet Connection Speed in ASP.NET

Here is code snippet that can be used to check the Internet connection speed in ASP.NET.

Here is the code snippet to check your internet connection speed (download speed).

 

Add namespace

 

using System.Net;

 

Write code in a Web application on a button click event handler. 

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'.");
}
