How to calculate file upload and download time using asp.net C#

Question

I have a scenario in which need to calculate the Server Time for uploading files as per the Connection speed.

Example:

Need to calculate time to upload files with Connection speed 256Kbps and more If connection breaks then checking the remaining time and restart the download or upload operation where it was break

Answer 1

256 Kbps = 32 kilobyte per second = 32768 bytes / s.

The size of your file is x bytes. So it takes (x / 32768) seconds.

If the connection is broken, you should query what was the last byte received by the receiver, put your filestream tot that position and continue.
