Enumaration revisited

Enum's can be used more efficiently and economically to describe constant values.
I tend to forget this syntax so here it is:


Example from Chess class. Elegantly describing chess piece using Flags in enum.
  [Flags]
        public enum PieceE : byte {
            /// <summary>No piece</summary>
            None      = 0,
            /// <summary>Pawn</summary>
            Pawn      = 1,
            /// <summary>Knight</summary>
            Knight    = 2,
            /// <summary>Bishop</summary>
            Bishop    = 3,
            /// <summary>Rook</summary>
            Rook      = 4,
            /// <summary>Queen</summary>
            Queen     = 5,
            /// <summary>King</summary>
            King      = 6,
            /// <summary>Mask to find the piece</summary>
            PieceMask = 7,
            /// <summary>Piece is black</summary>
            Black     = 8,
            /// <summary>White piece</summary>
            White     = 0,
        }

Explicit setting of type and value for Enum


    public enum MoveTypeE : byte {
            /// <summary>Normal move</summary>
            Normal                  = 0,
            /// <summary>Pawn which is promoted to a queen</summary>
            PawnPromotionToQueen    = 1,
            /// <summary>Castling</summary>
            Castle                  = 2,
            /// <summary>Prise en passant</summary>
            EnPassant               = 3,
            /// <summary>Pawn which is promoted to a rook</summary>
            PawnPromotionToRook     = 4,
            /// <summary>Pawn which is promoted to a bishop</summary>
            PawnPromotionToBishop   = 5,
            /// <summary>Pawn which is promoted to a knight</summary>
            PawnPromotionToKnight   = 6,
            /// <summary>Pawn which is promoted to a pawn</summary>
            PawnPromotionToPawn     = 7,
            /// <summary>Piece type mask</summary>
            MoveTypeMask            = 15,
            /// <summary>The move eat a piece</summary>
            PieceEaten              = 16,
            /// <summary>Move coming from book opening</summary>
            MoveFromBook            = 32
        }
