hello
you can try it
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");
Console.WriteLine("Done.");
}
catch
{
Console.WriteLine("Couldn't delete download file.");
Console.WriteLine("To delete the file yourself, go to your C-drive and look for the file 'speedtest.txt'.");
Console.ReadKey();
