Factory Pattern

[Jimbo]

Is this bad code? (C#)

I was under the impression that this is like a simple factory pattern, but
I now have my doubts (please ignore the lack of vallidation etc...)

void main ()
{
string s = "";
ProductFamily pf = new ProductFamily();
s = someUserInputString();
pf.getProductType(s);
pf.doSomePolyMorphicStuff();
}

public class ProductFamily
{
public ProductFamily()
{
}

public ProductFamily getProductType(string _prod_line_id)
{
ProductFamily productFamily;
return ProductFactory.getProductFamily(_prod_line_id);
}
}

public class ProductFactory
{
public ProductFactory()
{
}

public static ProductFamily getProductFamily(string productLine)
{

switch(productLine)
{
// end caps -- all the same
case "Insulating End Caps":
case "Conductive End Caps":
EndCap ec = new EndCap(productLine);
return ec;

// breakouts -- all more or less the same dimensions wise
case "3 Way Conductive Breakout":
case "2 Way Low Voltage Breakout":
BreakOut boot = new BreakOut(productLine);
return boot;

// all tubes, they are basically the same dimensions
case "Clear Insulating Tube":
Tube tube = new Tube(productLine);
return tube;

// boots -- inline and right angle are different
case "Inline Boots":
InlineBoot inBoots = new InlineBoot(productLine);
return inBoots;
}
}
}

How would I implement this with the factory or would that not be the
correct pattern to use?

Factory is the correct pattern to use here. The following article
might
help:
