Regions C# with Example



Regions C# with Example

A region is a collapsible block of code, that can help with the readability and organisation of your code. 
NOTE: StyleCop's rule SA1124 DoNotUseRegions discourages use of regions. They are usually a sign of badly 
organized code, as C# includes partial classes and other features which make regions obsolete. 
You can use regions in the following way: 
class Program 
 

{ 
#region Application entry point 
static void Main(string[] args) 
{ 
PrintHelloWorld(); 
System.Console.ReadLine(); 
} 
#endregion 
#region My method 
private static void PrintHelloWorld() 
{ 
System.Console.WriteLine("Hello, World!"); 
} 
#endregion 
} 
When the above code is view in an IDE, you will be able to collapse and expand the code using the + and - symbols.
