Shared naming conventions allow teams to collaborate efficiently. This rule checks that all enum names match a provided regular expression.
The default configuration is the one recommended by Microsoft:
- Pascal casing, starting with an upper case character, e.g. BackColor
- Short abbreviations of 2 letters can be capitalized, e.g. GetID
- Longer abbreviations need to be lower case, e.g. GetHtml
- If the enum is marked as [Flags] then its name should be plural (e.g. MyOptions), otherwise, names should be singular (e.g. MyOption)
Noncompliant code example
With the default regular expression for non-flags enums: ^([A-Z]{1,3}[a-z0-9]+)*([A-Z]{2})?$
Public Enum foo ' Noncompliant
FooValue = 0
End Enum
With the default regular expression for flags enums: ^([A-Z]{1,3}[a-z0-9]+)*([A-Z]{2})?s$
<Flags()>
Public Enum Option ' Noncompliant
None = 0,
Option1 = 1,
Option2 = 2
End Enum
Compliant solution
Public Enum Foo
FooValue = 0
End Enum
<Flags()>
Public Enum Options
None = 0,
Option1 = 1,
Option2 = 2
End Enum
