C# 7.0 Feature : Local Functions

With the release of C# 7.0, Microsoft adds a new feature called 'Local Functions' as enhancement of C-Sharp language, which allow you to local methods to be create and called within a method. 

A local function is available to the method it is defined inside only. 

See the below example:

I am creating add and subtract method inside main method and also calling in main method.

static void Main(string[] args) 

{    

  int Add(int a, int b) 

  {

    return a + b; 

  } 

  int Subtract(int a, intb)

  {

      return a - b;

  }

 

  Console.WriteLine(Add(3,4)); 

  Console.WriteLine(Subtract(10,3))

  Console.ReadKey(); 

}
