Can I ignore delegate parameters with lambda synta

Question

I am curious why C# allows me to ignore delegate parameters in some cases but not others.

For instance this is permitted:

Action<int> action = delegate { Console.WriteLine("delegate"); };

but this is not:

Action<int> action = () => Console.WriteLine("lambda");

Is there a way to initialize a delegate and ignore the parameters using a lambda? I know that I can add a single parameter to the lambda and fix the previous line but this is more of an academic question pertaining to the compiler and why or how this works.

Answer 1

I'd say it's to have a forced use of the parameters of the lambda expression.

Take your first example, how would you interact with the passed in value, there's no local representation of it.
