[c#] variables, ifs, simple math and drawing objects

[Hyperz]

Don't confuse using with includes. Using in C# is nothing but a shortcut and has no impact on performance.

Example:

System.Console.WriteLine("You know...");
System.Console.WriteLine("Writing system all the time gets anoying real quick.");
System.Console.WriteLine("That's why 'using' is the best thing since sliced bread!"); 

Why should we write the System namespace all the time to access the Console class? We don't. So we add:

using System; 

So we can just:

Console.WriteLine("You know...");
Console.WriteLine("Writing system all the time gets anoying real quick.");
Console.WriteLine("That's why 'using' is the best thing since sliced bread!"); 

We can also create an alias:

using System;
using c = System.Console; 

To do:

c.WriteLine("You know...");
c.WriteLine("Writing system all the time gets anoying real quick.");
c.WriteLine("That's why 'using' is the best thing since sliced bread!"); 

The closest you'll get to include()/require() in a language like C# is adding references to other assemblies in Visual Studio (well you can load them at runtime or even compile and run source code at runtime but that's on a whole other level, lol).
