Convert.ChangeType() 是否只是返回对传递值的不同类型的引用？

Question

The Microsoft docs say that Convert.ChangeType returns

An object whose type is conversionType and whose value is equivalent to value.

I'm not sure what that means. Here's my scenario.

ParentType parent = new ChildType();

Type type = parent.GetType();

parent.SomeMemberProperty = 1;

dynamic child = Convert.ChangeType(parent, type);

child.SomeMemberProperty = 2;

What then is the result of parent.SomeMemberProperty ?

EDIT: Please ignore the simplicity/stupidity of the above scenario. It's just meant to demonstrate the confusion I have and I'd never actually write that code.

Answer 1

Convert.ChangeType() does not copy the parent. It merely provides a differently typed reference to it, so any mutations to child will affect the parent object as well.
