Using parameters in BackgroundWorker handlers
You can assign the value of e.Result in worker1_DoWork
static void worker1_DoWork(object sender, DoWorkEventArgs e){ //Do the work //... e.Result = new MyParams();}Then you can get it in the worker1_RunWorkerCompleted in e.Result.
If you need to pass additional result value and you don't want to put MyParams object in the worker1_DoWork: e.Result - then you can create a small class ResultHolder with MyParams and MyResult as properties and use that class to pass the result in worker1_DoWork
