m Replaced AddOneToThree with AddOneToTwo. The former doesn't exist in ExampleTwo. |
||
Line 230:
public static class ExampleThree
{
public static int Evaluate() => ExampleTwo<IPrintExp>.
public static string Print() => ExampleTwo<IPrintExp>.
}
</syntaxhighlight>Notice that in ''ExampleThree.Print()'' we are printing an expression that was already compiled in ''ExampleTwo'', we did not need to modify any existing code. Notice also that this is still strongly typed, we do not need reflection or casting. If we would replace the ''PrintFactory()'' with the ''ExpFactory()'' in the ''ExampleThree.Print()'' we would get a compilation error since the ''.Print()'' method does not exist in that context.
