Passing array to method used on array member in c#

Question

i was wandering if there is a way to pass an array to a function that is used on its members( kind of like how you pass the "this" parameter to object).

instead of this:

void public foo(A[] arr){}
void main(){
arr[i].foo(arr);
}

this:

void public foo(A[] arr){}
void main(){
arr[i].foo();
}

edit: arr is array of A, foo belongs to A sorry for bad explanation first question.

• Johnathan Barclay: You could create an extension method.
• mjwills: If you go down the extension method route, I suspect you will want arr.foo() not arr[i].foo().
• Blindleistung: Sounds like you want to just do a foreach over the array and call foo on each item? foreach(A a in arr)foo(a); Or am I misunderstanding the question?
• Avishka Dambawinna: You mean like this, void public foo(data_type var) { .... } void main() { foo(arr[i]) }
• Noam Cohen: @JohnathanBarclay an extension method wont do because i want it to run on the objects inside the array and not the array itself

Answer 1

So... if I understand correctly. You want to call an item in the array, with a reference to the array.

But you don't want to pass that reference to the array?

I can only think of a working solution where you make a new class that encapsulates the array[] and create an add method, that upon adding handles the reference binding. (so passing a ref of itself to the added object). So that the items in the array hold a reference to the array.

or maybe you can do some nifty stuff using indexers:

Hope this helps!
