CA1712: Do not prefix enum values with type name

CA1712: Do not prefix enum values with type name








Breaking Change


An enumeration contains a member whose name starts with the type name of the enumeration.

Names of enumeration members are not prefixed with the type name because type information is expected to be provided by development tools.

Naming conventions provide a common look for libraries that target the common language runtime. This reduces the time that is required for to learn a new software library, and increases customer confidence that the library was developed by someone who has expertise in developing managed code.

To fix a violation of this rule, remove the type name prefix from the enumeration member.

Do not suppress a warning from this rule.

The following example shows an incorrectly named enumeration followed by the corrected version.

using System;

namespace NamingLibrary
   public enum DigitalImageMode
      DigitalImageModeBitmap = 0,
      DigitalImageModeGrayscale = 1,
      DigitalImageModeIndexed = 2,
      DigitalImageModeRGB = 3

   public enum DigitalImageMode2
      Bitmap = 0,
      Grayscale = 1,
      Indexed = 2,
      RGB = 3
