c# object oriented programming foundamentals

Question

I'm new of the Object Oriented Programming methods:

I have a class MyClass1 as follow:

public class MyClass1
{
    public int id { get; set; }
    public string name { get; set; }
}

There is also a class MyClass2 defined as:

public class Myclass2
{
    public int id { get; set; }
    public string name { get; set; }

    public Myclass2(MyClass1 m) { }

}

MyClass2 exists only if exists MyClass1, because in MyClass2 I need some properties of the MyClass1.

The best for me will be some like this:

MyClass1.MyClass2 = new MyClass2();

Ofcourse the constructor of MyClass2 should take MyClass1.

What is the best method to achieve this using C# Object Oriented Programming ?

I think this wants the homework tag, and some clarification, before we see a flood of upvotes. — Tetsujin no Oni

based on your example its best to delete MyClass2, it adds nothing. How would MyClass2 be different? — Jodrell

Inheritance:

public class Myclass2 : Myclass1
{
    public Myclass2() { }
}

You may also want to look at Nested types

public class Myclass2
{
    public class Myclass1
    { 
        Myclass1(){}
    }
}

It looks like MyClass2 should inherit from MyClass1, but you've not really explained what you are trying to accomplish well enough to be sure that's what you want.

agreed: inner class might be a better option for OP depending on usage
