Difference between Clone and Copy method

class A {
   internal A A; // non-private fields is the bad coding style, but this is just for example
   internal Name;
} //A

A a = new A();
A b = a; // a and b reference the same object:
// if you change a.Name, b.Name will change

b = a.MemberwiseClone();
// not a and b are distinctly different objects
// they can have different names:
a.Name = "This is a";
b.Name = "This is b"; // different, you can check it up after this statement.

// Now, how about a.A?
// After cloning, it still references the same object, because A is a reference type:
A a = new A();
a.A = new A();
a.A.Name = "inner";

b = a.MemberwiseClone();
b.A.Name = "another inner";
// it will change a.A.Name! Why?
// because we cloned a, but not a.A
