In C #, # The role of Region

The # region and # endregion commands are used to mark a piece of code as a block with a given name, so that the code can be better laid out on the screen. For example:

    /// <Summary>
   /// Parses one line in a gedcom file.
   /// </Summary>
   Class gedcomline
   {
       # Region Fields

       // Parts of the gedcom line.
       Private int level;
       Private string tag;
       Private string data;

       // Expression pattern used to parse the gedcom line.
       Private readonly RegEx regsplit = new RegEx (
           @"(? <Level> \ D +) \ s + (? <Tag> [\ s] +) (\ s + (? <DATA>. + ))? ");

       // Expression pattern used to clean up the gedcom line.
       // Only allow viewable characters.
       Private readonly RegEx regclean = new RegEx (@ "[^ \ x20-\ x7e]");

       // Expression pattern used to clean up the gedcom tag.
       // Tag can contain alphanumeric characters, _,., or -.
       Private readonly RegEx regtag = new RegEx (@ "[^ \ W.-]");

       # Endregion

       # Region Properties

       /// <Summary>
       /// Level of the tag.
       /// </Summary>
       Public int level
       {
           Get {return this. level ;}
           Set {This. Level = value ;}
       }

       /// <Summary>
       /// Line tag.
       /// </Summary>
       Public String tag
       {
           Get {return this. Tag ;}
           Set {This. Tag = value ;}
       }

       /// <Summary>
       /// Data of the tag.
       /// </Summary>
       Public String data
       {
           Get {return this. Data ;}
           Set {This. Data = value ;}
       }

       # Endregion

       .

       .

       .

    }

In the vs editing view, you can zoom in:

    /// <Summary>
   /// Parses one line in a gedcom file.
   /// </Summary>
   Class gedcomline
   {

        Fields

       Properties

       .

       .

       .

   }
