Objects owner (C#)

I've got two classes, one of which is a member of the other.

Code:

public class MyClass
{
    // Fields, Constructors, Methods, etc...
}

public class OwnerClass
{
    // Fields, Constructors, Methods, etc...
    public MyClass MemberClass; 
}

The MyClass object (that is MemberClass in the OwnerClass object) needs to get some data from the specific OwnerClass object that owns it. Is it possible to simply have a pointer to the owner, and is it safe to do so? If not (to either question), what is the best way to be able to access owner data?

This is one way, at least:

C# Code:

Original - C# Code
public class MyClass { // Fields, Constructors, Methods, etc... private object _Owner; public MyClass(object Owner) { this._Owner = Owner; } } public class OwnerClass { // Fields, Constructors, Methods, etc... public MyClass MemberClass; public OwnerClass() { this.MemberClass = new MemberClass(this); } }

public class MyClass
{
    // Fields, Constructors, Methods, etc...
    private object _Owner;
 
    public MyClass(object Owner)
    {
        this._Owner = Owner;
    }
}
 
public class OwnerClass
{
    // Fields, Constructors, Methods, etc...
    public MyClass MemberClass;
 
    public OwnerClass()
    {
        this.MemberClass = new MemberClass(this);
    }
}

I am not sure if there are better ways.

I had been under the mistaken impression that declaring an object in a class in such a way made a separate copy of that object. After a little more research it's clear that an object that I make in this way is really only a reference to the object that it's set to. In other words, if I change the original OwnerClass object independently of the MyClass object, it's automatically reflected in the MyClass object because it's only a reference. This makes things a whole lot easier than I thought they would be.

If I'm wrong about that please let me know. I'll take a lack of response as acknowledgment that my understanding is correct.

Or maybe someone could be too lazy or busy to reply back.

A class is a reference type, so you would only pass a reference to it; not make a copy of it.
Anyone, please correct me if I am wrong.
