c# - how to implement stream readtimeout property -

-

i'm fixing bug : app hang in download process 5 minutes while losing network connection. need reduce hanging time 20 seconds.

log snippet:

severe  2016-01-27 , 11:03:14     在 httpsdownload.dodownloadbyhttps(filedownloadinfo fileinfo, downloadingdelegate downdelegate)     message: init method:get  info    2016-01-27 , 11:08:29     在 httpsdownload.writetofile(filedownloadinfo fileinfo, stream stream, downloadingdelegate downdelegate, boolean clear)     message: exception while reading response stream     exception:         message: time out         type: system.net.webexception            在 system.net.connectstream.read(byte[] buffer, int32 offset, int32 size)    在 httpsdownload.writetofile(filedownloadinfo fileinfo, stream stream, downloadingdelegate downdelegate, boolean clear)

code snippet:

private void dodownloadbyhttps(filedownloadinfo fileinfo, downloadingdelegate downdelegate)         {                 //code                 webresponse = (httpwebresponse)webrequest.getresponse();                 responsestream = webresponse.getresponsestream();                 writetofile(fileinfo, responsestream, downdelegate, bclear);         } private void writetofile(filedownloadinfo fileinfo, stream stream, downloadingdelegate downdelegate, bool clear)         {                 int count = stream.read(readbuffer, 0, blocksize);                 while (count > 0)                  {                     //code                     count = stream.read(readbuffer, 0, blocksize);                 }         }

i believe timeout occurs in stream.read according log. easiest way trick should stream.readtimeout = 20000, can't set readtimeout property. way can think of write class override readtimeout like:

public class mystream : stream { //code public override int readtimeout { get; set; } //code }

but it's not preferred. better way fix bug?

the timeout needs set in webrequest object, of type httpwebrequest.
