C# Adding and Removing Anonymous Event Handler

suppose I have an Action delegate declared this way:

public event Action<MenuTraverser.Actions> menuAction;

I am associating a method to it this way:

menuInputController.menuAction += (MenuTraverser.Actions action) => this.traverser.OnMenuAction(action);

Now, all works fine, but in certain situation I need to remove the delegated method and I don’t know how.
I tried this way but doesn’t work:

menuInputController.menuAction -= (MenuTraverser.Actions action) => this.traverser.OnMenuAction(action);

How can I do such a thing? I need that my method OnMenuAction will be no longer called.

Since your signature seems to match (assuming that you have a void return type), you shouldn’t need to add an anonymous function but you can use the method group directly:

menuInputController.menuAction += this.traverser.OnMenuAction;

And in this case unsubscribing should work as well:

menuInputController.menuAction -= this.traverser.OnMenuAction;
