c# - How to display file upload progress in progressbar - Amazon S3 bucket -

i display file upload progress in progress bar on web page while uploading file amazon s3 …

on web page select file file input calls controller ajax post request .

in controller extract file posted request.

var hpf = request.files[1]; 

then call method uses amazons3client..

uploadvideomultipart(hpf.inputstream,filename) 

this above method completes upload s3 fine , during process repeatedly sends number bytes uploaded .

public static void uploadpartprogresseventcallback(object sender, streamtransferprogressargs e)         {// process event.              var progress = (string.format("{0}/{1}", e.transferredbytes, totalcontentlength));         } 

example:

transferredbytes totalbytes

8778 152652556

2562 152652556
