Calculating Download Speed and Estimated Remaining Time in C#

Calculating Download Speed and Estimated Remaining Time in C#

To calculate the download speed and the estimated remaining time of the download, you can follow these steps:

  1. Save the start time: Save the time when the download starts. This can be achieved with DateTime startTime = DateTime.Now;.

  2. Save the current download position: During the download, save the current download position. You can do this by saving the number of bytes already downloaded.

  3. Calculate download speed: The download speed can be calculated by dividing the number of downloaded bytes by the elapsed time since the start of the download. This can be achieved with double speed = downloadedBytes / (DateTime.Now - startTime).TotalSeconds;.
