c# - How to upload a mp4 to a stream through a console application using http put requests in the cloud? -

i have cloud console application. 1 of options upload mp4 file users computer.

the file gets read filestream , sent data controller http put request.

the data controller receives said http request of streamed file, finds/creates blob store file, uploads blob using streamed file.

when open , write stream program throws exception:

code:

 //gets record user wishes add video  int recordnumber = 0;  console.writeline("please enter record wish change");  recordnumber = int.parse(console.readline());    response = await client.getasync("api/samples/" + recordnumber);  if (response.issuccessstatuscode)    {     //gets video wish upload     console.writeline("please enter  filename wish upload: ");     string filename = console.readline();      //the path name of videos     string videopath = "api/data/" + recordnumber;      try       {        //reads file stream , sends data controller        using (var stream = file.openread(filename))        {          console.writeline("case 6 made using satement " +                              filename);           // httpresponsemessage response = await           // client.postasjsonasync("api/samples", stream);          response = await client.putasync(videopath, new                      streamcontent(stream));          console.writeline("video has been writen stream" + stream +  ""                              + videopath);           response.ensuresuccessstatuscode();          console.writeline("made it!!!!");          }       }      catch (exception a) { console.writeline("failed write stream: " +                                                 a); }                          }     else { console.writeline("success code unsuceesful: " + response); }     break; 

i have unsured media type yet still getting exception.

client.defaultrequestheaders.accept.add        (new mediatypewithqualityheadervalue("application/json"));
