An enumeration is a set of named constants whose values are generally related. In Excel VBA, an enumeration statement (Enum) is made in the Declarations section of a standard or public class module. In C#, an enumeration is defined directly within a namespace. By default, the first enumerator is assigned the value of 0 and the value of each successive enumerator is increased by 1.
Excel VBA
Tip: IF the enum description, contains blanks or special characters, then surround the enum name with brackets ([ ]).
Public Enum OfficeProduct
Access2007Only = 1
[MSAccess95-2003]
Excel2007Only
[MSExcel95-2003]
[XML]
End Enum
C#
public enum OfficeProduct {
Access2007Only=1,
MSAccess95_2003=2,
Excel2007Only=3,
MSExcel95_2003=4,
XML=5};
