Fastest way to run two tasks asynchronously and wait until they end

Question

Okay I need to change this..

void foo()
{
    DoSomething(1, 0);
    DoSomething(2, 3);
}

to something like this...

void foo()
{
    //this functions is sync.. I need to run them async somehow
    new Thread(DoSomething(1, 0));
    new Thread(DoSomething(2, 3));

    //Now I need to wait until both async functions will end
    WaitUntilBothFunctionsWillEnd();
}

Is there a way to do this in Silverlight?

Answer 1

void foo()
{
    var thread1 = new Thread(() => DoSomething(1, 0));
    var thread2 = new Thread(() => DoSomething(2, 3));

    thread1.Start();
    thread2.Start();

    thread1.Join();
    thread2.Join();
}

The method Thread.Join() will block execution until the thread terminates, so joining both threads will ensure that foo() will return only after both threads have terminated.

Answer 2

Task task1 = Task.Factory.StartNew( () => {DoSomething(1,0);});
Task task2 = Task.Factory.StartNew( () => {DoSomething(2,3);});
Task.WaitAll(task1,task2);

You'll need to add the Microsoft Async package (and it's dependents) to your silverlight project.
