Question

In my application, I used to create along string of async operations, which passed in functions like this:

public void LotsOfAsync()
{
    DoAsync1( ()=> { DoAsync2( ()=> { doAsync3( ()=> { finalAction();}) } ) } );
}

However, now I have moved many of those async operations into separate classes and objects but I want the same results. Mainly I have moved those async operations into classes which become part of a collection.

I’d like my new code to look like this:

public void lotsOfAsync()
{
    DoAsync1();
    for each ( MyClass in Async1List)
     { 
          MyClass.DoAsyn2(); 
      }
    if (allAsyncOperationsAreComplete)
    {
        FinalAction();
    }
}

What things do I need to do, to get this to work? Thanks.

Using the Answer below about Tasks, something still seems to be lacking. The program never continues even after throwing everything into a BackgroundWorker.

Answer 1

You can use Task<T> (using the Task Parallel Library for Silverlight) – something like this maybe:

List<Task> tasks = new List<Task>();

Task.Factory.StartNew(() => DoAsync1()).ContinueWith(_ =>
{
    foreach (MyClass myClass in Async1List)
    {
        tasks.Add(Task.Factory.StartNew(() => myClass.DoSomething()));
    }
    Task.WaitAll(tasks.ToArray());
    FinalAction();
});
