MethodInvoker vs Action for Control.BeginInvoke

Question

Which is more correct and why?

Control.BeginInvoke(new Action(DoSomething), null);

private void DoSomething()
{
    MessageBox.Show(\"What a great post\");
         


        

Answer 1

Also per MSDN:

MethodInvoker provides a simple delegate that is used to invoke a method with a void parameter list. This delegate can be used when making calls to a control's Invoke method, or when you need a simple delegate but do not want to define one yourself.

an Action on the other hand can take up to 4 parameters.

But I don't think there is any difference between MethodInvoker and Action as they both simply encapsulate a delegate that doesn't take a paremter and returns void

If you look at their definitions you'll simply see this.

public delegate void MethodInvoker();
public delegate void Action();

btw you could also write your second line as.

Control.BeginInvoke(new MethodInvoker(DoSomething), null);
