What is the use of #region and #endregion in C#?

Question

Give me an example of what can be achieved if I use a region block, and what is the use behind the wording after the region declaration?

#region MyClass definition
//Some code
#endregion

Answer 1

There is no (technical) reason to use #region.

The only thing it does is provide an easy way to collapse code.

As an example, for a relatively bulky class; I tend to separate some things in different regions:

• Constructors and properties
• Private or protected methods
• Public methods.

That's just one example. You can separate code however you want, it has no effect on how the application works.
