Context.Response.End() and Thread was being aborted

Question

I am trying to close the response using Context.Response.End but receive error "Thread was being aborted".

How do I correctly close the response without triggering an exception?

try {    Context.Response.Clear();    Context.Response.ContentType = "text/html";     //Context.Response.ContentType = "application/json";    JsonObjectCollection collection = new JsonObjectCollection();    collection.Add(new JsonNumericValue("resultcode", 1));    collection.Add(new JsonStringValue("sourceurl", exchangeData.cUrl));    collection.Add(new JsonStringValue("filename", fileName));    collection.Add(new JsonStringValue("filesize", fileSize));    collection.Add(new JsonStringValue("fileurl", Common.GetPDFURL + outputFileName));    JsonUtility.GenerateIndentedJsonText = true;    Context.Response.Write(collection);   try {      Context.Response.End();   } catch (ThreadAbortException exc) {      // This should be first catch block i.e. before generic Exception      // This Catch block is to absorb exception thrown by Response.End   } } catch (Exception err) {  } 

Solved by myself, the code should look like

try {   Context.Response.End(); } catch (ThreadAbortException err) {  } catch (Exception err) { } 

Answer 1

Is there a specific reason you aren't using context.ApplicationInstance.CompleteRequest() instead?

This method will short circuit the ASP.NET pipeline (except for the EndRequest event) without throwing the ThreadAbortException so you won't need the extra try/catch block, and you will also experience better performance.
