[C#] "Linking" 2(or more) objects to each other

[Gismo359]

So, I started learning C# recently and needed a way to "link" 2 objects together so if I am given 1 of them, I can get its corresponding one.
For example, if I have a Button in a TabPage, and I am given one of them I can get the other.
The first thing that came to mind was putting them in an arrays with the same index, but I want to know if there is a better way of doing this.

Thanks in advance

Keep a reference to the other in each one.

Could you please elaborate? I am kinda of a noob

EDIT: NVM, I figured it out.

I am assuming your button exists in the tab page, so the tab page can access the button.
When you create the button, pass it the tab page as a reference, and save it in the button, so you can get back to the tab page from it.

For 1:1 relationships a simple reference to its partner is sufficient.
For 1:N relationships you need an array, vector or list of references. Hashtables with named elements also work (how interpreters work) however since it resolves the location at runtime it is considerably slower than a direct address. Linked lists are fine for iteration but a vector is recommended if you want specific elements at known positions.
For sharing a pool of objects among each other it is inefficient to keep a list privately to each one. Instead use a container object (some implementations of lists are these) which you reference from each object. This means you have a N:1 relationship with the list object.

Or, you can just create a container class, and pass it's instance to it's children through their setter.

class ContainerClass
{
    private MyType1 object1;
    public MyType1 Object1
   {
        get{return object1;}
        set
        {
            object1 = value;
            object1.Parent = this;
        }
   }
   ...
}
