Question

I have a web service that receives requests from users and returns some json. I need to save the json string in the database so for the moment, the write query occurs before the response is sent back.

Is there a way to send the response first and then do the write query, after the response left the web service?

Thanks.

You can do schedule a query work like

ThreadPool.QueueUserWorkItem(state => 
      this.AsynchronousExecuteReference());

 // and run
 static void AsynchronousExecuteReference()
 {
    // run here your sql update
 }

One other example using Thread inside an class and you can pass parameters to it.

public class RunThreadProcess
{
    // Some parametres
    public int cProductID;

    // my thread
    private Thread t = null;

    // start it
    public Thread Start()
    {
        t = new Thread(new ThreadStart(this.work));
        t.IsBackground = true;
        t.SetApartmentState(ApartmentState.MTA);
        t.Start();

        return t;
    }

    // actually work
    private void work()
    {
        // do thread work
        all parametres are available here
    }
}

And here is how I run it

  var OneAction = new RunThreadProcess();
    OneAction.cProductID = 100;
    OneAction.Start();

Do not worry about memory, CG knows that this process is used until the thread ends, so I have check it and CG not delete it and wait the thread to ends.
