But we can consume the member by creating the object

If you make the class constructor Private you can achieve the same.It won't allow an object to be created of Parent class.

Ex:
class Parent
{
private Parent()
{ }
}
class Child:Parent
{

}
Error:
'ConsoleApplication4.Parent.Parent()' is inaccessible due to its protection level
