Have an egg pain,

 public class Parent 
{
Public Parent () 
{
The Init (); 
} 

Protected virtual void Init () 
{
} 
} 

Child: public class Parent 
{
Private int someproperty=1; 
Public Child (int I) : the base () 
{
Enclosing someproperty=I; 
} 

Protected override void Init () 
{
//this time I will always be the initial value 1 
If (I==0) 
Dosomething 
} 
}

The Child (int I) - & gt; The base () - & gt; The init () - & gt; Enclosing someproperty=I;
