Protected string name = "John L. Malgraine ";
 
Public virtual void GetInfo ()
{
Console. WriteLine ("Name: {0}", name );
Console. WriteLine ("SSN: {0}", ssn );
}
}
Class Employee: Person
{
Public string id = "ABC567EFG ";
Public override void GetInfo ()
{
// Calling the base class GetInfo method:
Base. GetInfo ();
Console. WriteLine ("Employee ID: {0}", id );
}
}
 
Class TestClass
{
Static void Main ()
{
Employee E = new Employee ();
E. GetInfo ();
}
}
/*
