How to do it...

This recipe requires a lot of attention due to the number of files that we will need to handle. Overall, we will create a parent class DecisionTreeNode, from which we will derive the other ones. Finally, we will learn how to implement a couple of standard decision nodes:

1. First, create the DecisionTreeNode parent class, as shown in the following code:

{ 
    public virtual DecisionTreeNode MakeDecision()
