Already defined delegate

Question

I heard once that .net introduced an already defined delegate with no parameter that we could use instead of creating one.

I'm having a hard time finding it and for what version of .net. (if it really exists)

Thanks!

Answer 1

Yes, it's called System.Action. If you are not using .NET Framework 3.5 (where Action was introduced), you can perhaps instead use System.Windows.Forms.MethodInvoker which has the same signature.
