.NET 4.0 Generics Beginner's Guide

A special Tuple<> pattern

Since Tuple is a new inclusion in the .NET 4.0 Framework and can prove to be handy in a lot of situations, I thought it would be a great place to showcase an unusual use of this beautiful data representation technique.

Let's say we have situations involving four integers. This is generally represented using nested if-else blocks, as shown in the following code. However, we can use a Tuple to refactor this code, as we shall see in a while:

1. Create a console app and add these four variables:

   static  int x = 11;
   static  int y = 9;
   static  int z = 20;
   static  int w = 30;

2. Now, add these nested if-else blocks in the Main() method:

   if (x > 9) { if (y > x) { if (z > y) { if (w > 10) { Console.WriteLine(" y > x and z > y and w > 10 "); ...
