Question

Imagine I have some code to read from the start to end of a file like so:

while(sw.readline != null) {  } 

I want this to be fully asynchronous. When deriving from IHTTPAsyncHandler, where would this code go and where would would the code to get the content of each line go?

Answer 1

I recently added some asynchronous processes to my ASP.NET pages in order to allow some long-running processes to take place while the user waited for the results. I found the IHTTPAsyncHandler quite inadequate. All it does is allow you to spin off a new thread while the page begins processing. You still have to make your own thread and create a AsyncRequestResult.

Instead I ended up just using a normal thread in my codebehind instead, much more succinct:

using System; using System.Web; using System.Threading;  namespace Temp {     public partial class thread : System.Web.UI.Page {         protected void Page_Load(object sender, EventArgs e) {             Thread thread = new Thread(new ThreadStart(myAsyncProcess));             thread.Start();         }          private void myAsyncProcess() {             // Long running process         }     } }
