Delayed function calls

Question

Is there a nice simple method of delaying a function call whilst letting the thread continue executing?

e.g.

public void foo()
{
    // Do stuff!

It's indeed a very bad design, let alone singleton by itself is bad design.

However, if you really do need to delay execution, here's what you may do:

BackgroundWorker barInvoker = new BackgroundWorker();
barInvoker.DoWork += delegate
    {
        Thread.Sleep(TimeSpan.FromSeconds(1));
        bar();
    };
barInvoker.RunWorkerAsync();

This will, however, invoke bar() on a separate thread. If you need to call bar() in the original thread you might need to move bar() invocation to RunWorkerCompleted handler or do a bit of hacking with SynchronizationContext.
