I have a class that is listening to a lot of action’s, and then when these are invoked do a similar thing but to different objects depending on which action was invoked. My thoughts are:
If I have
System.Action<SomeType> SomeAction;
void SomeMethod(SomeType type);
I can do
SomeAction += SomeMethod;
My question is then, if I have another class say
void SomeOtherMethod(SomeType type, SomePredefinedType)
Is there a way to do something like
SomePredefinedType SomeValue;
SomeAction += SomeMethod(SomeValue);
that is, to Subscribe a method with two arguments to a action with one argument by predefining the exces argument?
>Solution :
You can’t do it with a method group conversion like this, but you can easily do it with a lambda expression:
SomePredefinedType extraArgument = ...;
SomeAction += value => SomeOtherMethod(value, extraArgument);
