The #region and #endregion directives define a region that will be expanded or collapsed when using outlining in the Visual Studio IDE.

The general form is shown here:

#region region-name 
 // code sequence
#endregion

using System;

class MainClass
{
  [STAThread]
  static void Main(string[] args)
  {
      #region Stuff 
          
    
      #endregion

  }

}
