C# async/await Progress event on Task<> object

Question

I\'m completely new to C# 5\'s new async/await keywords and I\'m interested in the best way to implement a progress event.

Now I\'d prefer

Answer 1

When using a Task.Run lambda I have used an Invoke Action inside of this to update a ProgressBar control. This may not be the best way but it worked in a pinch without having to restructure anything.

   Invoke(new Action(() =>

               {
                   LogProgress();
               }));

Which takes it to...

        private void LogProgress()
        {       
          progressBar1.Value = Convert.ToInt32((100 * (1.0 * LinesRead / TotalLinesToRead)));
        }
