Is there a way to get effect1 with the method in effect2?

I want to be able to invoke the child most method with out testing for

any ideas?

Hi Your_Persona,

You need to change virtual to override. Replace your classes with the
following.

class grandParent
{
public virtual string daddy()
{
return " daddy's name is Adam";
}
}
class parent : grandParent
{
public override string daddy()
{
string ret = " daddy's name is Bill";
return ret + " who's " + base.daddy();
}
}
class child1 : parent
{
public override string daddy()
{
string ret = " daddy's name is Charlie";
return ret + " who's " + base.daddy();
}
}
class child2 : parent
{
public override string daddy()
{
string ret = " daddy's name is Chingy";
return ret + " who's " + base.daddy();
}
}
class child3 : parent
{
public override string daddy()
{
string ret = " daddy's name is Champy";
return ret + " who's " + base.daddy();
}
}

Cheers,
Chester
