How to check the Control.InvokeRequired Property ?

[yuessir]

My project has some snippet like:

if (InvokeRequired)
            {
                BeginInvoke(action);//action is Action type
            }
            else
            {
//Invoke
                action();
            }

I wanna refactor to following:

if (InvokeRequired)
            {
              InvokeAsync<Foo>();//action is Action type
            }
            else
            {
//Invoke
               Invoke<Foo>();
            }

How can I get the bool value,InvokeRequired?
