After searching and analyzing I have found that client was disconnected and still I am flushing the response which I am doing for creating PDF files from the stream.

To fix this kind of error we can use Response.IsClientConnected property to check whether client is connected or not and then we can flush and end response from client.

Here is the sample code to fix that problem.

 if (Response.IsClientConnected)
           {
               Response.Flush();
               Response.End();
           }

That’s it Hope this will help you..Stay tuned for more.. Till that Happy Programming!!

  1. Have to be honest, errors like this were the reason I switched from managing my own remote desktop connections to licensing remote connection software that does it for me. I stand by this decision.
