==Factory Method Patterns==

<source lang="csharp">using System;
using System.Collections;
public abstract class Section
{
public abstract void SomeSection();
}
public class TitleSection: Section
{

public override void SomeSection()
{
Console.WriteLine("title.");
}

public TitleSection(){;}

}
public class HeaderSection: Section
{
public override void SomeSection()
{
Console.WriteLine("header.");
}
public HeaderSection(){;}
}
public class FooterSection: Section
{
public override void SomeSection()
{
Console.WriteLine("footer.");
}
public FooterSection(){;}
}
public class MenuSection: Section
{
public override void SomeSection()
{
Console.WriteLine("menu.");
}

public MenuSection(){;}
}
public class CatalogPage: Page
{
public override void AddSection(){
this.pageCompositor.Clear();
this.pageCompositor.Add(new TitleSection());
this.pageCompositor.Add(new FooterSection());
}
public override void DisplayPage(){
Console.WriteLine("Catalog page contains:");
foreach(Section c in this.pageCompositor)
c.SomeSection();
}
public CatalogPage()
{
this.AddSection();
}
}
public class ManualPage: Page
{
public override void AddSection()
{
this.pageCompositor.Clear();
this.pageCompositor.Add(new MenuSection());
this.pageCompositor.Add(new FooterSection());
this.pageCompositor.Add(new HeaderSection());
}
public override void DisplayPage()
{
Console.WriteLine("Manual page contains:");
foreach(Section c in this.pageCompositor)
c.SomeSection();
Console.WriteLine();
}
public ManualPage(){;}
}
public abstract class Page
{
protected ArrayList pageCompositor = new ArrayList();
public abstract void AddSection();
public abstract void DisplayPage();
}
class Client
{
static void Main(string[] args)
{
Page p = new CatalogPage();
p.AddSection();
p.DisplayPage();

p = new ManualPage();
p.AddSection();
p.DisplayPage();

}
}</source>

==Use a static class factory==

<source lang="csharp">using System;

class MyClass {
int a, b;

// Create a class factory for MyClass.
static public MyClass factory(int i, int j) {
MyClass t = new MyClass();

t.a = i;
t.b = j;

return t; // return an object
}

public void show() {
Console.WriteLine("a and b: " + a + " " + b);
}
}

class MainClass {
public static void Main() {
int i, j;

// generate objects using the factory
for(i=0, j=10; i < 10; i++, j--) {
MyClass ob = MyClass.factory(i, j); // get an object
ob.show();
}

Console.WriteLine();
}
}</source>
<pre class=codeResult>a and b: 0 10
a and b: 1 9
a and b: 2 8
a and b: 3 7
a and b: 4 6
a and b: 5 5
a and b: 6 4
a and b: 7 3
a and b: 8 2
a and b: 9 1</pre>
