Get Download and Upload Speeds C#

Question

Hi Everyone,

I'm looking for a class or a library or anything that will allow me to get the current download speed, I've tried a lot of code from the net including FreeMeter but can't get it to work.

Can some provide any sort of code just to give this simple functionality.

Thanks a lot

I'm guessing you want kb/sec. That is determined by taking kbreceived and dividing it by the current seconds minus the starting seconds. I'm not sure how to do the DateTime for this in C#, but in VC++ it would be like so:

COleDateTimeSpan dlElapsed = COleDateTime::GetCurrentTime()
                           - dlStart;
secs = dlElapsed.GetTotalSeconds();

You then divide:

double kbsec = kbreceived / secs;

To get kbreceived, you need to take the currentBytes read, add in bytes already read, then divide by 1024.

So,

   // chunk size 512.. could be higher up to you

   while (int bytesread = file->Read(charBuf, 512))
   {
        currentbytes = currentbytes + bytesread;
        // Set progress position by setting pos to currentbytes
   }



   int percent = currentbytes * 100 / x ( our file size integer
                               from above);
   int kbreceived = currentbytes / 1024;

Minus some implementation specific functions, the basic concept is the same regardless of language.
