How to get the class instance which creat another.

[Steven.Xu]

How to get the class instance which creat another. For example:

public class A
{
private B bb;
public void CreatMethod()
{
bb = new B();
}
}

My question is how can I get the instance of class A through bb.
Thanks!

One way is for A to pass a reference to itself to B's constructor:

public class A
{
private B bb;
public void CreatMethod()
{
bb = new B(this);
}
}
public class B
{
public A _parent;

public void B( A parent )
{
_parent = parent;
}
}

Thank you William for your help. But as I know that's not a good way. I hear
from my friend that .Net has some method for get the create instance through
the object which created by it. Who know that method. Please give a
notification. Thanks!
