Refactor request: Convert comment to region, or vise versa

Before refactor, select the following lines:
````C#
// randomize input
var a = Console.ReadKey();
x = a.KeyCode.ToNumber(randomSeed);
````
The Refactor changes the first line of the comment to Region text, and surround the selected code with a `#Region`.

````C#
#region randomize input
var a = Console.ReadKey();
x = a.KeyCode.ToNumber(randomSeed);
#endregion
````

A vise versa refactor change the above lines back to the original one.
